    At least they made an effort, but they shouldn't suggest you to use your insurance for what is obviously a warranty issue.

    Same problem here (sd card unexpectedly removed) on Note II since few hours ago, without even using phone at the time. My card is 32GB SanDisk... The card still works, but gives me problems each time phone would go to "sleep". And every now and then it says its unreadable, so I have to remount it.

    I think there might also be problem in Sandisk, since 99% of failed cards are sandisk made 32GB+.

    I'll use warranty if it fails, but will also buy 32GB Samsung card, as I havent read one single problem regarding Samsung cards with Note II/SIII. It says somewhere that u should use Samsung microsd, so while I wont claim Samsung did something on purpose, but there is certainly a pattern. Maybe there is some minor difference in voltage or who knows...

    Edited to add this:
    I am now reformatting it to exFat, as by default it was in Fat32, but I doubt that will solve the problem. There goes 30EUR...

    I am now using my 8gb Samsung card that came with my old continuum. Battery monitor widget is writing its history files to it, so I can see how it performs.

    Are there apps that can monitor the health of an SD card?

    Tomorrow or Fridayi am going to visit the Verizon store and also see if Costco can pull up the receipt for purchasing the SD card and get that replaced.

    count me in my sd card which is 3 years old failed last night I got the card unexpectedly removed error I don't know whether the card just went bad or whether this has something to do with the phone. the good news is I don't really need the card because I don't download much music or take photos so maybe I'll just leave it, however I would like to know if the phone did something to the card

    After reading around, this seems to be very common problem, so i think every SIII and NOTE II will eventually kill sd card. Weird is the fact that most cards are Sandisk 32GB+; mine is 1.5 months old and worked perfect untill few hours ago. Even more interesting is the fact that i havent seen one Samung sdcard complaint. Maybe that's just a coincidence as most normal cards sold are probably by sandisk.

    Anyway i did full format, so it will be done soon and I will report if the problem reoccurs. Any other ideas I could try with sdcard to make it work?

    My card was a Samsung, see my post above.

    Someone on XDA thinks it's heat-related, the card is too close to the processor.

    My 32GB Sandisk Micro SDHC failed me too, today. I was using the camera when randomly, the photos that I save to my MicroSD disappeared out of my gallery. Which lead me to discover my SD card was 'unmounted' so I thought it was a rare glitch and immediately removed and reinserted the SD card. Now it won't even recognize that it's inserted. I see the option to mount the SD card but it is greyed out, but recently it displayed a blank sd card error. I have gotten this before with my 16gb micro sd card which I replaced with this 32gb only to get the same error in the end. Something has gotta be wrong with these phones, I've used that 16gb with my Droid X for 2 years without any problems and that's the same card that originally comes with that phone.

    My card was a Samsung card. 16 gb from my former phone (Samsung fascinate). The card isn't fried, but I kept getting the error that it needed to be formatted, or that it had been unmounted (when it hadn't been). On more than three occasions, every file on the card was wiped clean. Since the most recent incident, I've kept the card out of the phone. I'm using Dropbox, and I'm paranoid to even try putting the card (or any card) into the phone.

    And no, the card was not handled a lot either. I removed it once from my original phone (to put into the new phone), and three times from the GS3.

    I've been thinking the same thing. It's right next to the battery which gets very warm as well.

    I'm hoping that I can get a new receipt and do a warranty claim with SanDisk and perhaps get some answers from them about a possible cause. Has anyone sent their card in for a warranty claim?

    This phone doesn't seem to get that hot to me. My old phone would get very hot, not warm, but HOT! It had pretty much the same location for the SD card slot, and it didn't cause any problem. I haven't put my card in this phone after reading all these posts. I think I'm going to put one of the cheap 2gb cards I have laying around in here and see what happens before I put my good card in. I really don't think the heat is the problem.

    My 32gb scandisk SD had the same problems, after using it a while it can't be read. Not to mention it is my 3rd copy. My 1st copy was bought from a local store which don't allow return/exchange (Warranty is valid but a lot of process in between), so i thought that i might get a bad/fake copy. So im force to buy another copy (scandik 32gb) at a big chain store retailer as it looks legit. After a while my 2nd copy get the same problem it cant be read or stated as blank SD card. Finally i bought my 3rd copy in Singapore airport in one of my trip, this time also scandisk 32gb but the android version. It works great for around 3 months until it died out yesterday!!! It is very frustrating!!

    So guys if there is any solution pls post it T.T

    Thanks

    Point taken, but it was the Samsung rep who told him to have his phone repaired or replaced. He shouldn't have to pay an insurance deductible for something out of his control while the phone is still under warranty.

    I guess if the card is completely dead, then there is no fixing it, since U can't even format it or anything. I did full format (not quick) to exFat yesterday (it was in fat32 originally), which took 1h+ to complete, but haven't had problems since. There is definitely something fishy going on. Yesterday it would complain every few mins about sd card being unexpectedly removed or cannot read on its own (typical symptoms of failing sd card), but now after formatting it works perfectly.

    Well, since somebody also had problems with samsung card, I cannot even blame sandisk anymore. I daily access my memory card, but still - it shouldnt go bad in 6 weeks. I still have few 2gb cards several years old, one of which even survived swimming in Adriatic sea. Either this new cards quality control is crap compared to old ones, and/or Note II/SIII are killing sd cards over time, the length of which is pure gamble.

    So, to all the people that never had problems, that's great for U, but that might and probably will change. :)

    offtopic: Yesterday i was sure i need new sd card, so i found SDHC Samsung 32GB C10 (MB-SSBGA/EU) for 20eur in local store, which i think is a bargain for eu. Any thoughts on it? I have no intention on waiting for warranty claim if sandisk fails completely.

    I guess I'm going to have to just follow this thread, because I don't know what to do anymore. I want to get a new sd card, but I am lost on which one to pick now, because if it is just going to fail on me like my last 2 cards then whats the point. I already lost important photos that I needed for my photography class's exam and now I can't even access anything on my SD card, because it keeps saying SD card removed.

    I managed to get a picture of the error that I keep getting

    Well my hot battery theory doesn't really hold up, because it rarely goes above 105 farenheit, even today while using google maps and making voice calls with power actually dropping while on the charger

    Had the same problem. Did full format to exfat, and so far no problems for 2 days. I don't get it how that could actually fix sd card hw problem if there was any, but for now everything works perfectly. Try formatting (not quick, as that didn't solve my problem) to exfat or fat32. 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...

    Just got a new S3 and ordered the Samsung 32GB card off Amazon. To rule out that it came defective, at least, I'm going to run a health test program (H2test2 1.4) as soon as I get it.

    it won't let me post links as a new user, but here's the urls without the link:

    I have had not one problem with my 16GB SD card in the S3. Sounds like its your phone

    To be honest, I think the lower the capacity of the SD card the less likely it is to be corrupted. Most of the problems are with 64GB cards and to a lesser extent, 32GB cards. I've had three 64GB Sandisk cards corrupt in two S3 devices.

    Oh, okay. Your phone has had no issues. So it isn't a problem for you. "Sounds like its your phone", is an excellent point to contribute to the thread. I wish more people would. And no one should bother reading the thread before commenting either.

    This is a good point! The "read/write" function in the S3 may have difficulties writing the larger blocks. That could be why not as many users as you would think are having these problems. Just a thought.

    Thanks for the info. It sounds very reasonable. I see many people theorizing that the problem is fairly limited to 32 and 64 gb SanDisk. The primary reason behind that is most likely those are the most common sizes people are using.

    As an aside, I am not sure of forum rules here, but it is generally frowned upon to link to other forums. Since the post was your own you could simply cut and paste it.
