Default 2 phones, different carriers....

Hello all i just registered this forum because I had the sd card unmouting on my s3 yesterday.
I want to add that my wifes s3 also had the same problem about a month or two ago.
First I want to apologize because my post will be long.
Anyway my wife and I each bought the s3 on black friday week 2012 and I bought two 32gb sandisk ultra from amazon right on black friday. She has verizon and I have T-mobile.
She experienced the issue first. I removed the micro sd and tried to insert it in the micro sd reader and my pc would not see it at all. It appeared dead. Well I was persistent and finally i decided to get my old blackberry bold. Inserted the micro sd and it recognized it with all the files in it. After the BB recognized it, then my pc card reader was able to read it. So i backed up the stuff (mainly pictures, since we have our phones to save pics and vids on the external sd), I reformatted the card (fat32, as it was before) and put the pics back. She hasn't had issues since. I tought maybe it was an app causing the issue, but yesterday out of the blue, my phone said that the sd unexpectedly unmounted. Now my mistake with mine was to remove it and reinsert it back on the s3. Big mistake because what happened was that all my pictures got dumped in the lost.dir folder. Then i tried to insert it in my BB Bold and it wanted to format it but couldn't, it would give me a fatal error. Then i insert it in my pc card reader and it could only see 30.6MB out of the 32GB. So my pc would say if i wanted to format my card to 30.6MB. After i would press ok, it would say the card was locked and could not format. I then used a different micro sd reader, one that is basically just usb to microsd. And magically it was reading it. The only problem is that all my pics and vids got dumped in the lost.dir folder. So since yesterday I have been using a recovery tool to recover my pics and vids. It has been about 10 hours so far and it says another 4 hours to go.
My sggestion if it happens is, remove it from the s3, try to find a device that can read it, like a BB phone or a simple usb to microsd reader. Don't give up, especially if you have important stuff.
In the meantime, whether it's the phone, or the card, or a jellybean issue, maybe we ought to just come up with best ways to back up all the stuff whether via a software or via cloud (which i don't prefer). Just the simplest, yet most efficient way of backing up all the suff.
I for now will simply connect the phone to the pc once a week and copy all the new pics to my pc.

I am usually just a reader of forums but felt i should comment after reading other peoples experiences. My 3 month old S3 kept giving me the message 'preparing SD card' when it had not been removed, not being particularly tech savy myself my husband started to investigate. He found all the data from the card was missing, and neither his S3, my old HTC or our Samsung tablet even recognise that the SD card has been inserted . The card is a samsung 4GB card which has never given me any problems before now, and has only been handled to be moved from one phone to another, once. In desperation to retrieve the photos of my children that were on the card (which yes, I know I should have backed up more often, and it is to my loss that I didn't) I have looked a quite a few forums discussing this issue. There was one other like mine, where the card error seemed to co-incide with a rapid loss of battery life? I don't know what this means but thought I should mention it. If anyone has any advice about how i might be able to get any device to even recognise the SD card has been inserted that would be fantastic? I am pretty much resigned to the fact I have lost everything and the SD card is likely dead.

I've had the same issue. I am on my second SD card. The first one was a SanDisk 8G that my PC and wife's phone will no longer recognize either. Now, I have a Lexar 16G card in. It did the "unexpectedly removed" deal on Saturday. I did a format with the PC and seems to be working for now.
Every phone out there has it's issues. Guess this one just needs to be backed-up more often than most.

Are the cards that are experiencing issues Class 10? I've read numerous stories where Class 10 cards can have some corruption issues?

Thumbs up

This is interesting because I was searching for an SD Card speed topic as I was curious to know whether the Ultra High Speed SD card that I bought was worth the money or whether I wouldnt get any higher speeds than Class 10.



Now that I've stumbled on this topic it will make me want to test it each week to determine whether any corruption has occurred or loss of speed or data. I've only had it since April the 4th so far and nothing wrong has happened but I will report back here if I do find something I dont like regarding the SD card.

I tested the speed with the program Android Tuner and I'm happy with the results. The first picture is the Android internal SD card speed with associated cache sizes and the 2nd picture is the Ultra High Speed external SD card with associated cache sizes.





If anyone knows of any SD card speed topics it would be good for me to have the link, as the forum search feature doesn't let you include the letters "SD" together because it says they're too commonly mentioned.

Okay, guys.. after some testing with the Kingston Class 10 64GB card that I bought a week ago, I am starting to suspect that it is due to the class of the card. It is causing issues in my Samsung Galaxy Victory similar to what users here are experiencing with their S3

When I first received the card, I put it into my phone and it recognized it immediately and I transferred my data to the card from the old one. My computer confirmed that the card was in exFat format. A day later when I was taking pictures I get a notification that says "sd card damaged". I removed and reinserted and it was fine again. I then recorded a video and halfway through the same notification popped up again.

I then removed the card and formatted the entire 64GB to FAT32 format thinking the phone just didn't know how to utilize exFat system efficiently. I got better results and did not get the damaged card notification when taking pictures and videos taken did not trigger the notification but they recorded "glitchy" .. I downloaded "SD Card Tester" from market and ran it using a 450MB test read/write file. The speeds on write started off at 6MB/s and as it approached the 12MB/s range it stopped and began stuttering it's way to the end of the test write (note that on my class 4 32gb card this ran multiple times without a hitch). So it seemed that when writing to the card achieved the higher speeds it began having problems writing. This happened every time I ran the test and a few times it didn't finish writing to the card at all and the application notified me that the card was damaged (although it wasn't, it just couldn't function well at the high speed). Although, while doing the read test the app was able to read from the sd card at amazing speeds and it did perfect every single time.

My 32gb class 4 card performed the read and write test perfectly every single time but it never exceeded 9MB/s. So I am highly interested in running this same test with a lower class 64gb card to see if it is in fact the high write speeds causing issues. After reading around, I see it is not recommended to use class 10 cards in phones as they are more suitable for digital cameras and camcorders etc..

Any thoughts on this guys?

for those whose cards failed, did you format your card to exFAT or FAT32?

First two SD cards that failed were class 10. But then, I replaced them with other lower-speed cards -- and they both worked fine -- until last week, when one of them failed.

Since most of the cards folks buy are likely class 10, that could also be why most of the failures are with class 10 cards. But the one that failed most recently was class 4.

64GB?
If so, exFAT or FAT32?

Formatting to FAT32 sovled my issues. No SD card errors since I did this in late January.

Do you see any glitches when performing a 300MB read/write test with the SD Card Tester App? Just curious

Of course I lost all my pictures and such. I tried all the programs to recover, tried adapters on the computer, I followed all the suggestions. Then gave up and tried to format it, that didn't even work, seeing that I could not format it... Hey I just thought according to all the smart people (sarcasm) online it must be dead, even though I never had an SD card die on me in any of my other 50 devices that used various SD cards.

So I just felt horrible for buying a budget SD card PNY, I didn't think was that bad, but now knew it was trash since it just died on me less than a year, and back when the EVO was out class 10 16 gig was expensive that was almost 4 years ago.

This time I thought I was not going to skimp on the card, I went straight for SanDisk Ultra 32 GB MicroSDHC Class 10 UHS-1 from Amazon even made sure according to those wonderful lemmings online on posts about this, it was an official SanDisk SD card that I had to cut open.

So Got my new card everything was peachy keen for about a month, and please get the wonderful irony in this, last Friday I bought my mom an Siii from Sprint because they were having a sale for them for $50. I thought to myself I had to upgrade her crappy SD card and I ordered her the same card...It comes I install it in her new Siii and less than an hour later the SD card in my phone says either SD card removed. Insert a new one. or SD card is blank or has unsupported files. So it appears my Siii struck again... I immediately took the SD card out of my mom's phone and told her its better to use the internal storage. Of course all my pictures and things are gone. Over 400 pictures! back up back up you say... okay I have after my last lesson most of them are on my dropbox but still not all of them. YET THIS SHOULD NOT HAPPEN TWICE IN A ROW. I refuse to just believe that "SD cards just die" I call BS maybe once in a while but not like this.

I think there is a problem with this phone and Samsung will never admit it since they sold over 30 million phones and are the envy of Apple, but I was hoping that someone on here could prove it, figure out how to fix the SD cards to recover the information or prevent this, and or take some kind of poll to see how common this is with the Siii I have a feeling this is a known issue to someone/I will not be buying another sd card to use with a phone again. This experience is abhorrent.


I've found this youtube video youtube.com/watch?v=1fjNkQkQZ2U
WOW!! i had the same thing happen to me! I got a 32GB sd card patriot card class 10 for my htc evo 4g a few years ago. never had a problem. then about a month ago with my Samsung galaxy S III I restarted my phone normally and when it came too it had messed with the sd card and was unread able and i lost everything i had on the card. i looked in to this matter a small bit and found out that Samsung phones do this time to time.

You can probably get your data off fine (I did) and use the card again, but I would not trust it.

I bought a Lexmark 16GB sd card and for about two weeks, no problems. A bunch of photos and videos was saved on the card.

Then, all of a sudden, "SD card unexpectedly removed" message came and went a few times, for a couple days. The card was still being recognized intermittently.

Then, the card became invisible to the phone. No messages, as if it was not there. No reaction from the phone to being removed and inserted, as if the card was bad.

I put the card in a computer SD card reader, and it was recognized and accessed with no problems. Thankfully, all my files were still there. I immediately copied the files to the computer. The card was scanned and no problems found of any sort. I believe Lexmark is off the hook there.

I reformatted the card in the SD card reader, using FAT32 option and Windows 8 Storage function under Computer Management. I then inserted the card back in the phone, and it recognized the card with no problems.

I will continue using the card in the phone, but, I am not going to trust it. I was lucky to get my files, but from my research, some are not so lucky. Best save your files off the card frequently.

I will post again if the problem reappears, or I get more info. On a side note, I am coming from HTC Inspire, and, with few exceptions, I liked that phone and the interface much better. The only things about S3 that I like are the screen size and the easily removable battery. In everything else, HTC was way better, IMHO. Plus, HTC Sense blows the default Galaxy software away. I had to switch providers so there was no choice but to switch phones as well. Damn the US cellphone business model
Unfortunately, problems, and worse, continue. The card worked fine for a few days. Then, again, "SD Card Unexpectedly removed".. but that was not the worst, yet. I let it the S3 cook it another day, just to see what would happen. Now, it says "SD card is damaged" and offers me to format it. No thanks, Samsung! I took the card out again and put it in the same computer reader as before. The card is reported as corrupt. I have not yet run any recovery software on it to see if the data is salvageable.

VERDICT: Samsung Galaxy S3 slowly corrupts SD cards of various brands, capacities, and classes, by slowly COOKING them over time. Not sure what it does to it, and if it is a hardware or software issue, but something needs to be done about it.

FAT32 did not solve my problem. Same card as yours. It's probably worth trying if somebody wants to, but it's not a guaranteed fix.

Default Same issue SIII OS 4.1.1 few days after update

Messaged me for mandatory firmware update, before I drive to a WiFi, I rebooted, and had SD card corrupt message.

My phone is 11 days old, my 32 Gb Pny Class 10 card is 5 days old.

Card was fried.

Put card in card reader on PC. Could not open usb drive, and a right click on the drive to see if I could format locked up My Computer in XP.

Tried again several times, same. Gave up.

Never seen anything like it. Will buy a 16 Gb card (I have a high level phone so I can be limited to a crappy 16 card and will be lucky if it does not get fried.

Firmware update could not be done, USCELLULAR says a WiFi firmware update after the OS update commonly says "Network Failure or Cannot connect to Server" .... I should seek out a corporate store that can apply the firmware update by PC usb connection.

I think I will reset the phone and not update anything for a year.

We have had three Electrify phones for a year with 32 Gb cards, and never a problem.

Maybe in Asia they buy the 32 Gb internal memory phones, and forget about the external cards.

Pretty bad Samsung. If anyone has ever heard an official explanation from Samsung, it would be nice to hear.....

Guess they prefer to spend their time on the next phone coming out.

I kept on having problems with my San Disk ultra 36 gb card that it kept on showing unmounted, corrupted etc. But then I went into setting- developer options - and checked "protect sd card". I'm not exactly sure what that does but all I know is that for a week my sd card is behaving. I'm not getting any stupid error messages. So it's worth a try!

Hmm interesting. That setting is supposed to require apps to request permission before accessing sd card.

Default SanDisk

The Sandisk 32gb and 64 gb class 4 speed have known issues with Galaxy s3 and are even draining the batteries and slowing the phone down. Call Sandisk for a replacement or just throw the sandisk out. I bought a Samsung SD and the phone works great now.

Well i had both. Class 4 and class 10 32gb, for me it seems that class 10 Kingston works for almost 6 months now without a glitch... It's N2, but had same symptoms. And on a class 4 sandisk I also saw just a fraction of actual size. Couldn't bring it back with any of two readers, nor Nokias...

Hi guys,

Using S3 9305 4G, I have read the entire thread and my feel is more towards S3 not stable to handle SD cards.

I am using Kingston 16GB Class 10 and 8 GB class 4.
They are working, BUT when I transfer files like videos avi. etc..... the movies are only half transfered. some remain in the card and refuse to transfer. I had to "try" copying from card to phone and to phone to pc. Sometimes that works often it doesn't.

I am kind of disappointed being the SD slot was one reason why I purchase an Android and not an iphone. Saying that, I have not seen any major issues coming from the S2.

I have corrupted files on my S3 at times and is a clear indication that this device cannot be trusted in storing any important files at all.

Yes, I agree to some extend Sandisk and some SD cards is probably crap and might be part culprit, but I think the phone has some part of it as well.

None of my data stored last over a few months. I can copy serveral video files to my phone and play them but I have issues copying them out from the card. The card seems to only have difficulties on this device.

Somebody posted the same suggestion a while ago. I tried it. Did not help me (SanDisk Ultra 64 GB card).

He ended up issuing an RMA anyway. Right before we ended the chat I did suggest "I wonder if I can be sure I'm getting a replacement manufactured after things were fixed." Then he said something like "We are working with Samsung on the issue. You won't have any issues with a replacement card." I'm not sure if he looked up the info with others or if he was just saying that to appease me. But anyway, I have an RMA.

I WAS surprised that they game me a prepaid shipping label to return my current card.

I'll post an update when I get the replacement (probably about 2 weeks) and have used it a bit to see if I still have issues or not.

Well, it's been a month since my post quoted above after davoid pointed out that apparently SanDisk has admitted to a manufacturing defect that can affect Galaxy S3 phones.

Took about 1.5 weeks to get the replacement. Ran great for about 2 weeks, and then just last week the issue returned with the new card. My main question is, how can I be sure that the replacement card I got was manufactured after they fixed the defect. The tech that I got the RMA from originally tried to assure me it would be okay, but obviously not. Or the issue is larger than their manufacturing defect. I can't be sure which.

Now I'm trying to track down another microSD card to try in my S3 for a while to see if it has issues, so if it doesn't I can try to convince SanDisk to replace mine again. (When I got the RMA the first time they asked if I had tried a different card, and I told them I don't have another card to try and I'm not going to go buy another one just to try it. He told me they'd replace it that first time, but if I had trouble again they would require me to try another card.)

Of course I lost all my pictures and such. I tried all the programs to recover, tried adapters on the computer, I followed all the suggestions. Then gave up and tried to format it, that didn't even work, seeing that I could not format it... Hey I just thought according to all the smart people (sarcasm) online it must be dead, even though I never had an SD card die on me in any of my other 50 devices that used various SD cards.

So I just felt horrible for buying a budget SD card PNY, I didn't think was that bad, but now knew it was trash since it just died on me less than a year, and back when the EVO was out class 10 16 gig was expensive that was almost 4 years ago.

This time I thought I was not going to skimp on the card, I went straight for SanDisk Ultra 32 GB MicroSDHC Class 10 UHS-1 from Amazon even made sure according to those wonderful lemmings online on posts about this, it was an official SanDisk SD card that I had to cut open.

So Got my new card everything was peachy keen for about a month, and please get the wonderful irony in this, last Friday I bought my mom an Siii from Sprint because they were having a sale for them for $50. I thought to myself I had to upgrade her crappy SD card and I ordered her the same card...It comes I install it in her new Siii and less than an hour later the SD card in my phone says either SD card removed. Insert a new one. or SD card is blank or has unsupported files. So it appears my Siii struck again... I immediately took the SD card out of my mom's phone and told her its better to use the internal storage. Of course all my pictures and things are gone. Over 400 pictures! back up back up you say... okay I have after my last lesson most of them are on my dropbox but still not all of them. YET THIS SHOULD NOT HAPPEN TWICE IN A ROW. I refuse to just believe that "SD cards just die" I call BS maybe once in a while but not like this.

I think there is a problem with this phone and Samsung will never admit it since they sold over 30 million phones and are the envy of Apple, but I was hoping that someone on here could prove it, figure out how to fix the SD cards to recover the information or prevent this, and or take some kind of poll to see how common this is with the Siii I have a feeling this is a known issue to someone/I will not be buying another sd card to use with a phone again. This experience is abhorrent.


I've found this youtube video youtube.com/watch?v=1fjNkQkQZ2U
In my case, the SD card, inserted into an adapter and plugged into the USB port, killed the USB port. After taking out the adapter, the port does not recognize any other devices, such as a mouse or a flash drive. The USB, however, continues to work for the SD card...
This has happed to me before. It ended up deactivating all USB ports of my Sony Vaio laptop - so I had to send it back to the manufacturer.
Has anybody had that problem, too?

You can probably get your data off fine (I did) and use the card again, but I would not trust it.

I bought a Lexmark 16GB sd card and for about two weeks, no problems. A bunch of photos and videos was saved on the card.

Then, all of a sudden, "SD card unexpectedly removed" message came and went a few times, for a couple days. The card was still being recognized intermittently.

Then, the card became invisible to the phone. No messages, as if it was not there. No reaction from the phone to being removed and inserted, as if the card was bad.

I put the card in a computer SD card reader, and it was recognized and accessed with no problems. Thankfully, all my files were still there. I immediately copied the files to the computer. The card was scanned and no problems found of any sort. I believe Lexmark is off the hook there.

I reformatted the card in the SD card reader, using FAT32 option and Windows 8 Storage function under Computer Management. I then inserted the card back in the phone, and it recognized the card with no problems.

I will continue using the card in the phone, but, I am not going to trust it. I was lucky to get my files, but from my research, some are not so lucky. Best save your files off the card frequently.

I will post again if the problem reappears, or I get more info. On a side note, I am coming from HTC Inspire, and, with few exceptions, I liked that phone and the interface much better. The only things about S3 that I like are the screen size and the easily removable battery. In everything else, HTC was way better, IMHO. Plus, HTC Sense blows the default Galaxy software away. I had to switch providers so there was no choice but to switch phones as well. Damn the US cellphone business model
Unfortunately, problems, and worse, continue. The card worked fine for a few days. Then, again, "SD Card Unexpectedly removed".. but that was not the worst, yet. I let it the S3 cook it another day, just to see what would happen. Now, it says "SD card is damaged" and offers me to format it. No thanks, Samsung! I took the card out again and put it in the same computer reader as before. The card is reported as corrupt. I have not yet run any recovery software on it to see if the data is salvageable.

VERDICT: Samsung Galaxy S3 slowly corrupts SD cards of various brands, capacities, and classes, by slowly COOKING them over time. Not sure what it does to it, and if it is a hardware or software issue, but something needs to be done about it.
Update 3:
Got around to playing with the cooked Lexmark SD card. In Windows, the card is seen but cannot be accessed. Disk scan cannot be run with error "Windows Can't access the disk" or something like that.
I scanned the card with Testdisk from GSsecurity (CGSecurity - Testdisk and Photorec are superb, nothing else like it, helped me many times when everything else, including Norton and other paid apps, etc, failed)
and it located the partition on the card, so it appears that card, as of yet, not entirely cooked. I was able to recover the partition using Testdisk but it still was not accessible in Windows 8.

I then applied Testdisk's File System Utilities, and it successfully found the files in the DCIM directory on the card, and copied them to another disk. It appears all files, nearly 100, have been recovered. This is encouraging since it appears the hardware of the SD card is not cooked. S3 just corrupts the data. PERHAPS it COULD be fixed with some firmware / software update on the Galaxy.

Windows Storage showed the partition as RAW. Interesting. At this point, there was probably a way to get the partition to function again, but I took a shortcut and just basically erased the partition, since I already got the files off.

Back into Samsung Galaxy Oven it goes. Card recognized, and Galaxy offered to f it all over again. No, not what you are thinking, although it is open to interpretation. It offered to f for format it, and I let it The card again appears fully functional. If it gets cooked again, and I doubt not it will be, I'll update.

I have a lowly, slow SD card, so having the latest and the greatest is not the issue.. this should not happen on a flagship phone anyways. One of the main reasons I got the Galaxy was because of the SD card capability. SD cards have been around for a looooong time, this is not new technology. There is no excuse, Samsung! Fix it.

I bought my wife an S3 last October. Recently noticed the battery life down to about 6-10 hours even with just on standby and no usage. Replaced with new double size battery but still had same problem.

Then I noticed the S3 was not seeing the 32gig Adata micro SD card.

I removed the card and tried it in my PC but it was dead. However the battery consumption returned to normal straight away. To my mind this is a straightforward hardware fault with the phone and not the SD card.

I heard about the general S3 problems through the memory supplier who agreed to replace the SD card under warranty this time but won't do it again for same device. Fair enough.

I had enough so I contacted Samsung and gave them a piece of my mind for the peace of my mind They said the fix is in place and will be released "soon". I told them soon is not soon enough, and if it isn't soon, I am going back to HTC and never coming to Samsung again. How they handle S3 problems will tell me everything I need to know about them, and if I would ever consider getting S4.

It's nice to know that they have something in the works and that I'm not just losing my mind. When my S3 ate a 1GB card from my old dumb-phone, I wasn't too bothered. Tiny card, never really used it, no great loss and I figured it had nothing to do with the S3. Now it's having all sorts of issues with the 32GB card. beginning to think I should take the SD card out and keep it out till they actually come up with this long awaited fix. Such a shame since I absolutely love my Galaxy S3. Wife's I-Phone 4S has given here WAY more grief than my phone has up to this point. Quite the unpleasant kick in the butt kind of issue. After going 9 months without any problems the S3 starts doing this crap.

When they have an official fix for this, please post it ASAP! I'd like to get a round to using the SD card I paid for.

Has anyone tested if having the camera storage settings set to memory card makes it more likely for the card to die? I've had a 64gb sandisk since february and the first thing i did was change the camera storage to memory card. But immediately i noticed the camera app crashing and slowing down so i changed it back to phone and now manually move the files to the card. Not sure if this was due to the card or just a bug with the camera but generally both the gallery and camera apps dont seem to handle memory cards very well. I wonder if this could be the reason for all the sd cards getting fried.

No issues with my Samsung 8GB Ultra High Speed SD Card the which is currently being used in the Samsung Galaxy S3. I switched on the camera pictures and videos to external SD option approximately 2 weeks ago

I have had my replacement 32GB class 4 SD card for just over a month now and it seems to be working fine so far. Then my original card lasted just over 4 months before it went squirrely...

Default Samsung says to format to FAT or FAT 32

The samsung manual for the S3 says to format the SD card to FAT or FAT32 only.

If your sd card dies completely, you won't be able to access it in any way, so it will be too late. I did the format only few hours after problems started so I haven't lost any data and was able to get sd card recognized on computer...

I've had my 64gb samsung card that I formatted to exFAT for 5 months now.

FYI, when I formatted it to exFAT on my computer and put it in my phone it didn't recognize the card. It recognized it after I formatted it again in my previous phone.

I have recently ran into this issue with 2 32GB cards and neither of them were SanDisk cards. After quite a bit of research, this issue seems to be less of the card manufacturers fault. My fiance and I both have S3's (sprint variant) and about a month ago her S3 killed her 32GB gskill card. Last night, my S3 killed my 32GB gskill card. Infuriated, I hit up Samsung's support...this proved to be rather useless. After reading threads after threads of people with this issue and trying multiple things myself (different phones i.e. blackberry, htc, other samsungs...the built in card reader on my laptop...etc) none of them worked.

Until....

Using an old alienware (aurora m9700 if it matters, but i doubt it) that was on windows xp (this i believe is key as to why this has worked for me..long live xp) heres what i did

1) tried the built in sd reader and an sd adapter...no luck

2) used an external reader inserting the micro sd into the micro sdcard slot (no adapter)...also no luck

3) used the same external reader, put the micro sd card into an sd adapter inserted that into the external sdcard reader and then plugged that into usb...like magic! back in business, i am currently running a backup of the sdcard.

I am unaware if this will carry over to anyone elses problems...but this card was dead to the world and was unreadable. I am also unsure if this will allow me to continue to use the 32gb in anything...at this moment I'm more concerned about backing up the data it contains.

Hopefully this can help some of you having this problem. Losing all that data really sucks!

-devx

p.s. I guess this is my first post here...I tend to lurk here a lot, but am much more active on xda, great community here btw as I've been frequenting this site for the past 2 years or so...oh btw

Hi nice to meet you all


UPDATE

Finished the backup of my sd card and am now attempting to backup my fiance's (hers died a month ago) The card did not want to read initially...in fact i started changing the sd card adapter i was using and cycling through the stack that I have and jackpot! Just got hers to read using the same method! I think the solution is to use a pc on windows xp, an external card reader ( i used a targus ) and then just keep playing with it. Try different sd adapters, try different usb ports...but if anything....be vigilant! Don't give up...or you know...give up...go calm down..then try again.

FINAL UPDATE

I was able to create a backup of both sd cards. I then reformatted...but to no avail, they seem to remain dead to other devices. I guess I'm just happy I was able to save the data from the cards. I may look into running some sd utilities to see if I can bring them back, but I'm not going to hold my breath

Hi devastatorx and welcome to the forum!

Great to hear you and your gf didn't lose your data!

Did you try reformatting in the card reader with XP? and if so, what file system did you attempt? FAT32? exFAT?

As it seems your cards aren't totally dead, maybe you should try to find a Nokia phone running symbian 9 (I think, off the top of my head) and try formatting in that phone. Apparently this has been known to bring back dead cards, and as you managed to retrieve your data, you might stand a good chance of success.

I was not able to get any of my data from my dead card, but I never tried using XP. It has since been replaced by SanDisk so no other attempts are possible. Fortunately nothing important was lost that wasn't backed up, but I would have liked to get it back.

Attempted to format as fat32, but will try again some time today with the SD Formatter utility. Even if I do get it to recognize, I'm not sure I would trust it enough to actually use it.

As for the Nokia, I think I might have an easier time getting a new Sd than tracking down a friend with one of these. Not very common around here (Indiana, USA)

Thanks for the tips

Think I solved my particular issue and if your galaxy s3 can't read your sd card but other devices can, this MAY help you. Initial question, how many of you having these problems use roms? Recently loaded wicked v10 onto my phone, initially on stock kernel. Decided I didn't like the red theme and reinstalled in, this time in AROMA installer, I chose the deviant kernel, all of a sudden, the sd card will not mount. I also have a samsung galaxy tab plus and suddenly it too was unable to read the sd card (sand 64 gb ultra class 10) However, my OG asus transformer and my pc could read the card no problemo. Formatted the card on the pc but the s3 still couldn;t read. At one point received blank sd card do you want to format? I said yes and after the s3 still could not pick up the card. Repeated format on the pc then I inserted into tab plus, formatted the card again on the tab plus, which was then able to read it. I inserted the card into the s3 and it's reading the card again. I think it's a samsung issue, not a sandisk issue. I don't even actually know what the issue is, but formatting the sd card on another samsung device and then inserting into the s3 may help some of you.

Samsung Galaxy Note II; Stock ROM; Not Rooted; Kingston 64 GB Class 10. OTG cable. MHL cable.
Worked fine for about six weeks...
Over the course of the last two weeks however...started noticing that after deleting photos the date order of the photos was starting to go glitchie (out of sequence). Then certain videos started pixelating and phone started throwing the dreaded "cannot play video" error with both camera created videos and downloaded movies. Would need to reboot phone at this point. Sometimes, while trying to play a video the phone would just hard reboot. As of yesterday the card is totally corrupt. Luckily, I put most of the good stuff onto Dropbox before the card totally when down the drain.
Put in a 16GB card from my old phone. No problems (so far).
My gut is telling me it's the phone, possibly with certain cards, affecting power users more than casual users (who seldom use the phone to it's full potential). Perhaps it's a timing issue writing or reading. A power management issue? Android as an OS is still rapidly evolving and the hardware manufacturers are cranking out the product as fast as they can -- perhaps we're just seeing the "bleeding edge" of this new technology.
~m
Update: I tried using my PC to recover data from this card using ZAR software. The first run reported bad sector, bad sector...bad sector to the Nth. Seemed hopeless. But once and a while the MBR would suddenly show up (for two days windows just offered to format this card because it read it as "unformatted". Then, I took the card in and out of my SD card reader a couple of times, and took removed and replaced it from the SD to SD Micro card shell, on the last attempt BANG! All files showed up! CTRL + A, CTRL + C them all to my RAID array. I had missed a few files and there were some non critical ones which it was nice to have back. The card appears to be fine
THE VERDICT: Dirty contacts caused what looked like a card failure. When I think about it the SD card isn't soldered and the phone is often carried close to or on the body, humidity could be oxidizing the metal. Might make sense to spray them with contact cleaner once and a while or buy a card with gold contacts.

It's been around a month and a half since I first purchased this SD card and an update on the data integrity and any speed loss so far is nonexistent. It has been a great performer.

I also wanted to test the zooming functionality on some 70 Megapixel and below pictures as somebody did have an issue with their pictures not zooming at one point, but like many problems, many are one offs which the huge majority just don't encounter at all.

Steps used to Fix the SD card:
1. S3 set Developer options (ON)
2. Set Protect SD card (checked)
3. Remove battery
4. Install 32g card
5. Install battery
6. Turn on S3

Download SanDisk Android app. - external 32g shows up - YES!!
Scandisk app https://play.google.com/store/apps/details?id=com.sandisk.mz
This was suggested by someone a while back in this thread. It might be worth a try, but it did not work for me, so it's not a guaranteed fix.

I just sent my second 32g lexar sd card back for another. First card lasted a couple months, contacted lexar sent it back to them put new card in formatted it this one lasted for 2 weeks. Contacted samsung they say they do not have any known issues concerning the s3 killing cards and so on. Also quizzed lexar and they have not had this problem till now told them to check the internet.
Anyhow someone needs to take the blame. My wife has the S3 also but she has a 2g samsung sd card that came in her admire she has had it in her phone since we bought the phones. And until my third new card comes I am using my old 2g sd card from my admire works fine. So if this one does not hold up will have to ask for a refund. And try the samsng sd card think they have the 32g for 49 bucks

Worked fine for about six weeks...
Over the course of the last two weeks however...started noticing that after deleting photos the date order of the photos was starting to go glitchie (out of sequence). Then certain videos started pixelating and phone started throwing the dreaded "cannot play video" error with both camera created videos and downloaded movies. Would need to reboot phone at this point. Sometimes, while trying to play a video the phone would just hard reboot. As of yesterday the card is totally corrupt. Luckily, I put most of the good stuff onto Dropbox before the card totally when down the drain.
Put in a 16GB card from my old phone. No problems (so far).
My gut is telling me it's the phone, possibly with certain cards, affecting power users more than casual users (who seldom use the phone to it's full potential). Perhaps it's a timing issue writing or reading. A power management issue? Android as an OS is still rapidly evolving and the hardware manufacturers are cranking out the product as fast as they can -- perhaps we're just seeing the "bleeding edge" of this new technology.

Update: I tried using my PC to recover data from this card using ZAR software. The first run reported bad sector, bad sector...bad sector to the Nth. Seemed hopeless. But once and a while the MBR would suddenly show up (for two days windows just offered to format this card because it read it as "unformatted". Then, I took the card in and out of my SD card reader a couple of times, and took removed and replaced it from the SD to SD Micro card shell, on the last attempt BANG! All files showed up! CTRL + A, CTRL + C them all to my RAID array. I had missed a few files and there were some non critical ones which it was nice to have back. The card appears to be fine
THE VERDICT: Dirty contacts caused what looked like a card failure. When I think about it the SD card isn't soldered and the phone is often carried close to or on the body, humidity could be oxidizing the metal. Might make sense to spray them with contact cleaner once and a while or buy a card with gold contacts.
Weird. I was just about to recommend Kingston c10 as it solved the issue for me. It's working on my Note 2 fine for almost 6 months now without so much as a glitch.

Before I had 32gb class4 Sandisk and after about 1.5 months it failed completely... Nothing could bring it back.

I am going to blame sdcard manufacturer and their QC. Even if one is made by Kingston and other by Sandisk, they might have actually been made by same manufacturer that had a bad quarter or something. Anyway Kingston 32gb class 10 works for me.

I have been using SanDisk Sd cards for very long and I have no problem with it other than the slow transferring rate at times. Usually, I buy a new sd card because I want a faster and an up to date card.

Hey there... found this thread while trying to figure out why my Galaxy SIII is telling me the SD card is blank or has unsupported...".

Just thought I'd add a data point...

My SIII is 8 months old with a Kingston Class 4 MicroSD card, which now is not readable by the phone or PC. I tried Image Rescue 4 to no avail.

I haven't tried the repair sequence mentioned earlier, but I will and report the results....

This just happened to me recently with a Polaroid 32 GB HC. Been working fine for almost a year until I power my phone off for a movie and powered it back on a couple hours later.

Now, I may be wrong.
Now that Google is planing to release a Samsung Galaxy S4 with Stock Nexus Android experience, I doubt it.
