Just thought I should let you all know about my recent experience with this microSD card.
The Part number is SDSDQY-016G-A11 or SDSDQY-016G-A11A
I bought one from my local Best Buy after finding the item was marked down from $49.99 to $17.99. At first, my initial thought was "Done!" I took it home, opened the package and began transferring everything from my 8gb card to this new 16gb class 10 card.
Now, here is where the problem starts. I do not know if I did not take the necessary prerequisites for this particular card, but, after about an hour of just basic copying of data to the new card, I was struck with a CRC error and the card forced ejected itself from the USB host. I removed the card and put it back in to see what happened and found a corrupted directory from the last thing the card was copying. I couldn't access it or delete it. I couldn't copy anything into the card either. I tried formatting, to which it would complete the operation with a "This card could not be formatted." message at the end. I tried downloading different partitioning software to delete the partition, format the unallocated space and create a new partition to which I was "then" greeted with a variety of "This card is locked/Failed Operation/Space cannot be formatted/Partition could not be created." I gave up. I went back to Best Buy and exchanged the card for a new one. I thought "F*** me right? I got lucky with a bad card."
Nope.
Same thing with the new card, except it happened within 5 minutes of copying anything onto the card. This time around, I decided that I am not going through all of that again and returned the card.
Again, I do not know if I took all the necessary prerequisites before handling the card, but, to my knowledge I do not think there could be anything.
Instead, I jumped over to Hhgregg and found a different model SanDisk 16gb microSD card. I was able to copying over everything over to that card the first time and without a problem.
Also, in case it's asked, the phone did pick up the card initially before anything was copied. After the problem's arose, the phone refused to mount the card at all.
So, if anyone was considering picking up this card, its up to you what you want to do. Just Beware.
I found that the SanDisk USB device/ other SanDisk Adapters was causing errors in the 15 or so misc cards I put through it. Were you using it? or was it in your phone?
I went with the 64GB SDXC and no issues since.
At first I used the supplied adapter which is when the first card gave out. The second card I used a different adapter. A USB based one and it still gave out but much faster. Initially I tried with the card in the phone, but it kept force ejecting itself from the USB host as soon as I started. I thought it was the cable at fault.

I have the same problem i purchased 16gb ultra yesterday and today i m unable to format this card in NTFS system it formatted succesfully in fat32 bt the speed i get white transferring any file is jus 3.5-4 mbps olease help any solution for that??
I have a 7 months old SanDisk ultra 32gb and it's still very good. I have better speeds when copy inside the recovery than inside the rom.
Did you report it to Best Buy?
My shiny new Galaxy S III has now destroyed two 32gig micro SD cards on me. About two weeks after I installed the first card, my phone started giving messages about the SD card being improperly removed, then it would immediately try to re-mount it, then would say it was removed again, then finally started just repeating the "unable to mount SD card" error until I physically removed the card. I argued with best buy to give me another one, and now today (about two weeks after installing the new one), the same thing happened. I put the card into a USB reader to try it on my computer, and now even my PC does not recognize the card.
Has this happened to anyone else? What can I do to fix this?! I pre-ordered the phone from verizon, so I'm now well out of warranty replacement time.

I have a 32gb MicroSD card and haven't had a problem. I do wish I could use it more as internal memory rather than hardly usable external storage...but that's a different issue.
Sorry I couldn't help, but just wanted to say that Galaxy S III does support that much external storage. Maybe a hardware issue? Try troubleshooting it with another MicroSD card.

Gotta be the cards you're getting I would think. I had a 16gb card that came with my Droid x almost 3 years ago in it for almost 2 months before the card finally crashed.(I'd abused that card tho, carried it in my jeans pocket, left it sitting on my table etc) Then I put my 64gb in it. It's been a little over two weeks now and no probs with it. I've written too it and erased and so on so I've actually used it. It's almost full now actually lol.
I have that same 16 GB from the droid x. Do I still need to format it if I flash a ROM? And how do I check what format its in

My 32gb card was doing that on stock until I finally installed a custom rom. No problem since.
Synergized GS3
SD card gs3 issue
I also had trouble with my external 16gb card after flashing 2 ROMs (synergy & beans v9). I was not even able to get a computer to recognize the sd card after the flashing.
I thought it had to do with using a stock, then rooted stock, then custom kernel. i thought the combination and repeated TBU access over a 4 day period just trashed it. maybe there is more to the story?
1) What is your ROM flashing history (what roms, how long were each installed)?
2) Which rom did you notice the problem on?
3) Were the original and replacement cards the same make/model?
4) What format were the cards in (FAT32, exFAT, or other)?
5) are/have you overclocked your cpu?

Thanks for the responses guys. I'm still fully stock, I haven't done anything to the phone (yet). I don't know what the format was, I just put them straight into my phone and let it do whatever it wanted to do. The original and replacement are the same make and model, from the same store. So before i panicked too much, I was considering buying a new/different card from amazon and seeing if it does the same thing still.
Just didn't know if anyone else was experiencing this, or had any thoughts on why that would randomly happen on a completely stock phone?

That sounds like your best bet. There are plenty of crappy cards out there. My ADATA 8GB class 10 has been great so far. I have noticed that the GS3 gets really hot right near the cards (micro sd and sim). Can't be great for the cards long term.
I've had my VZW GS3 since 7/5 and have been fine with my card. I've seen plenty of people who've had trouble with FAT32 vs exFAT, but none who have lost their card.
I have seen a ROM break cards before (an early AOSP gingerbread build for the Fascinate claimed one of mine), so I've actually been looking. This is the first thread I've seen.

I've also noticed it gets really hot toward the bottom of the phone. Now that I think of it, both times I noticed the SD card issue right after taking the phone out of my pocket. Maybe it's just getting too hot? I wonder if my case is also holding in a lot of the heat and making it worse? I wish there was a way I could test things without breaking an SD card every time!
My GS3 fried a new 32gb card that I put in it after about 3 weeks. Randomly got an "unreadable SD card error", can't correlate with any specific activity. I reformatted the SD card & it works again in the phone. I was rooted, running stock at the time. Maybe it's the heat, but I don't recall it being hot at the time (I also don't recall it not being hot...)
Try sandisk.I was having problems with lesser brand

I have been using the 32 GB San Disk brand card that came with my thunderbolt and it's been working great.
I really don't know what could cause that to happen to a card and I haven't noticed any other reports of it happening with this phone.
If it comes down to it VZW SHOULD give you a replacement because it could be something to do with the card slot in the phone. I would try talking to them if you can't get it worked out.
So going on the theory that maybe it's just getting too hot, I just ordered a 16gig sandisk ultra micro SD card. It claims to be "temperature proof", whatever that means. Hopefully that clears things up, otherwise I'll have to deal with Verizon, and I'll be super mad if they give me a refurbished phone when this issue actually started two weeks after I got the phone.
If I don't post back here then you can assume all has gone well!
16gb card from droid x
same as others, used the same 16gb card from my droid x, transferred to the bionic when it was released, and now have been using it in the GIII since release. no issues.
I don't believe the phones are getting too hot to do the damage. The hottest temp my battery has gotten had been 106 and they say that heat damage isn't even a concern until around 140 or so. I would think the cards could take the same if not more than the batteries.
I had a similar problem, my sd card wasn't destroyed, but it would randomly become unmounted. It started happening after I hooked my phone up to my corporate email and it forced me to encrypt my device. After I removed the corporate account it stopped happening. This was all on stock TouchWiz from the factory.

I have had my 64gb SD card for a month and so far nothing went wrong. did you buy your SD cards from a reputable source? I have always used sandisk SD cards try buying one from Sandisk or even Samsung. if you bought your card from ebay make sure the card works, I have heard that some times people sell damaged cards for very cheap. But other than that good luck.
16 GB class 10 sandisk 30 mb/s version died on me with this phone after 2 weeks, stock ROM, formatted with phone. It was brand new.
The error I had was it became read only. And no it was not fixable, I tried everything. Low level format, checking permissions, different OS's, putting it in SD adapter and messing with lock switch on there.
I read class 10s are more prone to die quicker and aren't necessarily better, but just different from a lower class. Ie a lower class will last longer because it read and writes differently and doesn't skip certain safeties like a class 10 does.
Running a class 4 16gb sandisk now and it is annoyingly slow.

im on my second s3 (first one screen shattered) which ive had for about 3 months now and since new i got a 32gb scandisk 10 sd card, everything was working fine till about a week agao then i started getting "sd card unexpectly unmounted" i would remove the card, reinstall, then would get the message " preparing sd card " then phone would show card but either say "blank card or unsupported files" then sometimes the phone wouldnt read that there was a card installed. i tried pressing mount sd card and nothing would happen.
now the strange thing i have a galaxy tab2 and the 32gb works great in that, so i tried formatting card with tab2, reinstalled iinto s3 and same problem. now i did take the 2gb card i had in my s3 and it works fine,the phone is rooted and have always ran Cleanrom or Wicked sensations roms. i did a loy of searchs but havent had much help on finding an answer.
somebody please help.
Bill
anyone?
I had the same problem, come to find out, it was a cheaply made sd card. Think I paid 10-15 bucks at most for a 32gb class 8 card. I bought a scandisc card and have been fine since.
And just for info.... I read online that others were having this same issue and that it was the card not seating in the slot very well. If you took your phone back to the store they would exchange it. I took it in, got a new phone, and the same thing happened (unrooted, rooted, romed, it didn't matter) Got a new card and it was fixed.

Have you tried connecting it to your computer via sd adapter to see if files are there. If you cant read any files it may be a bad card but you can always format it while connected to the computer and see if that helps. If computer reads your files i would suggest you move files to computer, format, then try it on your phone and if it still doesnt work than maybe its the problem suggested above my post with it not seating correctly. Good luck
this is my second last port of call i have a galaxy s2 i9100 running jelly bean 4.1.2...i have a kingston 16gig class 10 micro sd card for the phone now its been working just fine for the last couple of months until a few days ago, i went to get something out of the card and noticed it somehow unmounted it self, it gave no options to re mount if i pressed format it did nothing at this point i was getting worried i have so many pictures and videos saved on this card of family functions, so i took it out put into the pc and the pc wont recognise it if i go to device manager its very slow to refresh but when it does it still doesnt find the card at this point i have no way of getting into the card at all what i wanted to know is
1. is it possible that if the card reader in the phone is faulty could it damage the card to point where it cant be recognised at all in windows?
and
2. does anyone know how i can possibly get into this card to retrieve this info?
ps. at the moment im running a 2 gig backup card to see if its the reader in the phone but so far so good any help would be appreciated
My sd card wouldnt work after less than 1 year of use. Unfortunately, only a few files were saved because it lagged and neither the computer or my smarthpone would read it.
However, formating it solved the problem.
Some personal experience.
Ironically, I also own a Kingston. Now I just use it for music storage.
My phone is just over 1 year old now and I've never had any issues before. A few days ago I would get the message that the SD card was removed unexpectedly when it wasn't, and then it would work for a few hours and repeat. Now, I cannot get either of my 2 micro sd cards to be recognized by my phone. Both these sd cards are able to be read by my pc so I am confident they aren't corrupted or have an issue. Is this most likely an issue with the SD card reader in my phone or somehow the sd cards have been corrupted?

I have the same issue since last month. Tried to flash back to the stock 4.4.2 Rom (From Lollipop) and now the SD cards cannot be even recognized by the phone. My PC can read/write to the SD cards without any issues. It seems it is a common problem for LG G3 phone. Mine is D855 version though.
I just had that problem as well and it ended up with the SIM not being detected as well. Had to get a replacement. I assumed that the SD card/ SIM tray combo was a removeable component - it's not, it's soldered to the phone so I couldn't replace it. (D850) Now, I'm worried that this replacement is going to suffer the same fate... Hopefully later, rather than sooner.

Here is my update:
Sent in my phone to LG to be repaired and after receiving it back I had the same issue. LG claims they replaced the sim/micro sd reader. Then I thought it must be the software, so I downgraded to the stock software from the factory (4.4.1 I believe) and I had the same issue. Annoyed, I told LG they did not fix the issue and sent it to them again with the hope they would replace it but unfortunately I received it back and they claim all they did was update the software (4.1.1 -> 5.0.1) and obviously this did not fix the issue. At this point I simply just don't use a micro sd card anymore because of this annoying issue. Still searching for a solution..
Exactly my problem. So annoying!!! I've got my sim/sd tray replaced and the problem occured for the 2nd time after 2 weeks.
