Okay,
So I had a PNY class 10 for less than a year in my evo 4g, worked flawlessly. Bought a Sprint Siii, formatted my PNY and used it fine for a few months then all of a sudden one day my phone said I had a blank or unsupported SD card and that I had to format it. 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
Update*
So I wanted another SD card my phone space is full. I bought an Amazon basics class 4 8GB 1 week later its fried. Thanks Samdung. I'm probably not using you again.
in relation to this matter over my findings of this mysterious sd card problem.
"I to have been able to replicate the problem" So in order to find a solution to a problem sometimes you have to be able to replicate it to see how it can be fixed so here is my thoughts and please excuse me if someone has already duplicated this..
On this forum phandroid I had come across a app that is called SGS3EasyUMS
"which means Samsung Galaxy S3 Easy UnMountStorage from MTP then it turns your device into a MASS STORAGE DEVICE GaLS3 L710 and then my computer would only recognise my phone as a cd drive and would tell me I had to format my drive in order to use that part of my device. ???? strange
as for I was able to access it all the time before this took place.
it would show it as internal memory sd and ext memory as sd card when my phone was in MTP mode = allows transferring of files as media Im guessing the name MTP is for MEDIA TRANSFER PROTOCOL? which my computer has the drivers for.
and when I choose to switch from MTP to PTP which is Im guessing is PICTURE TRANSFER PROTOCOL?
it then loads another set of drivers for it so I can transfer just pictures or other media that don't support MTP.
Well when I chose this program to recognise my phone as MASS STORAGE DEVICE my computer is then supposed to load the correct drivers to it so it can be recognised appropriately. For the simple reason's MASS STORAGE DEVICE can be a cd-rom, hard drive, Large SD Known as "Secure Digital"
To rap all of this up
I can just simply say this I bet if you was to take an old android phone from like gingerbread or ice cream sandwich being factory installed and or Rooted or rommed to the max. and install your sd "Secure Digital" card in it and plug it into the computer through a usb data cable that is able to not just charge the phone but also for file transferring just like the one that comes with your
Samsung Galaxy S3 L710
it will properly start working no questions asked I bet you
because with those phones they supported the technology MASS STORAGE DEVICE MODE.
I know this will really help everyone big time.. so NO sgs3 does not kill cards its the drivers you install and the configuration over the computer and device your connecting to it..
"I may be wrong about this as for if this was the case I'am sure through booting the device it would remount the internal storage"
Another thought for the rooted users in here have you at anytime unmounted your sd through CWM OR any other recover modes like it.
might be a place to check as for if you have umounted your internal sd storage you may have caused this problem. No biggy as for we all make mistakes and some point of time..
Now if im wrong then someone please correct me as for I would only want to help. as for I'am seeing that this is a wopping issue here!
Please people if any of this has helped you resolve your issues.
Could you hit the thanks button as for this helps me help others in your same situation.. thank you for helping me help others
