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.

When I play video stored on my internal storage, it is smooth. I can watch a 90 minute movie video without noticing any glitch at all.
When I play video stored on my external storage, there are glitches. One glitch every 1-2 minutes. These are not big glitches, just a brief deviation that gets your attention. If I listen, I think it is skipping a fraction of a second of the audio. (It may be skipping a fraction or second of the video display also, but my eye doesn't detect it). It's not a huge deal: ...... but just something that I notice and it's a minor irritation.
Since it occurs only on external sd, not internal storage, I assume it is the speed of the sd card. I have a 16GB Sandisk SD card. If I remember right, it's "Class 6"
I don't hear any glitches when listening to MP3's off of external sd, works just fine with no glitch ever.
SUMMARY: no problems on internal sd, no problems on mp3's. The only problems are videos on external sd.
It seems to me that the external sd can't quite keep up with the high transfer rate required for video playback.
Has anyone else seen this?
Any observation about which SD cards do this and which don't?
By the way I'm running rooted 2.3.6 from qkster's package, with Zen's Infusion A kernel. Holo launcher.
I haven't tried boosting to 1600Mhz. I'll try that and report the results later.

I just tried it - no difference. Glitches still occurred with cpu max frequency set to 1600.
You should try to format your external card and then try again.
Also, it could be your external card is to slow on reading
Should not be that slow if it is class 6 though...
Maybe try other card on your infuse with same video file.

Thanks. I have also noted the SD card media scanner runs to scan my external sd card more frequently... almost every time the phone comes out of sleep. I think this symptom coincides with me adding more files to my external SD.
I will try reformatting now as you recommended.
Question: is it better to reformat sd card in the phone or on the pc?
(if on the phone, there is no question of file system... I'll let the phone pick the format. If on pc, I'm not sure what format to pick... I'm using Entropy's kernel with voodoo lagfix enabled... does that mean external cannot be formatted to FAT32? )
The bigger problem is the constant scanning every time I turn the screen on. It was a nuisance, and I think it was draining my battery.
It gave the error message "sd card unexpectedly removed".
There are threads on this for some other Samsung devices.

There was a suggestion Sandisk cards in Samsung devices tend to have the problem.
I transferred my files to my pc, formatted sd in the phone, no problem until I transferred files back... then problem started recurring.
I reformatted in the PC to Fat32. Put files back on. Seems to be much better. But very close monitoring using SD Card Monitor program....

... shows it is still have problems. I'm going to break down and buy another sd card. Perhaps another brand.

Your SD card has problem for sure.
It shouldn't scan that often and it shouldn't say it is unexpectedly removed.
Seems either phone's card reader or the card is very unstable. That is why you are having problems in video files.
If the SD card benchmark program shows that tour SD card is performing bad, I beehive you got fake Sandisk SD card or really low class SD card.
From this point, I believe getting new SD card is the best solution here.
PS. You should put the SD card on PC then run benchmark on PC to see how it performs on PC. If it performs too much faster on PC, then the problem might be your phone's card reader.

Symptom went away with new sd
Before replacing the sd card, I had 100+ sd card events recorded by theSD Card Monitor program in a 24 hours period.
After replacing the sd card, I have 0 events recorded by the SD Card Monitor program in a 24-hour period.
The new SD is a Lexar 32GB Class 10 for $45 at Target. (preformatted as FAT32)
It was cheaper than the $70 32GB SanDisk they're selling at Best Buy.
I'm tempted to say the problem is solved.
On the other hand, one thing I noticed on the old SD was that the old sd symptoms got worse with time... I don't think they were there when the card was new. So I'm not sure if I've really solved the problem or just reset the clock waiting for the new SD to act up under whatever influences degraded the old one. Time will tell. For the time being, life is good. That scanning upon coming out of sleep was a real PITA.. slowed down the phone just when you picked it up to use it... actually dropped two phone calls recieved while phone was sleeping.. I presume because the phone wasn't able to handle scanning and answering at the same time.
Perhaps it was a fake SanDisk. Where'd you buy it from? Lots of fakes on eBay.
I bought the SanDisk (that had the problems) at Best Buy.
I was going to post this in response to a couple of people in the development sections but my post count is too low so I'll post it here instead.
The SD slot in this phone seems to have an issue with corrupting SD cards, I've had to format both my old and new SD card multiple times with this phone as it becomes unusable every few days. I'm not versed enough in hardware to know if this is a bad connection between the SD slot and the "motherboard" of the phone. I've seen a number of people have their SD cards go bad with this phone and I assume that means we had a manufacturing issue. It would be really cool if a hardware hacker experiencing this issue could take a look inside and confirm whether or not the hardware is connected correctly.
Well, perhaps there's a high number of bad readers....
I've had the same card in my Q since the day I got it (mid-September), no issues.
Mine wouldn't read the day I swapped up from My Epic 4g Touch to This phone, So I popped in an sd reader backed up my data then let the Moto format it, no issues sence
Curious to know what class of card you guys are running. I've been running a Patriot class 10 but my previous was a class 4 without branding that came with my old Transform.
I'm really hoping that I just had my old SD card die at a bad time and that my newer SD card was just sent bad. Today I couldn't get the card to read from the SD slot in my computer, and it would not be cool if my phone caused it to become that way.

Class 10 Maxell
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2074251
No issues here. I tossed the crappy class 2/4 that shipped with my Epic long ago.
Well I found an extra class 4, 2 GB SD card lying around the house when I was cleaning today. It may be that the local shipment of phones was bad, so if this SD card goes on me then I'll try exchanging the phone in another town just to be safe.
Just out of curiosity does anyone know whether Sprint orders enough phones for replacements with their original shipments? I'm not from a very large town so I'd imagine they would keep replacing with phones from the same batch.
I've got a Samsung 32GB class 10 mSD.
Nearly everytime I reboot my Photon Q it says "SD Card is damaged".
Go into settings, Mount SD Card once or twice and it works.
I've read, that other Android Devices have also problems with that size of SD Cards. (Google)
I had also problem in recovery restoring a backup, the restore process didn't went correctly
(said that everything was fine), had to use my 2GB mSD, which worked nicely and the backup also.
So I think it's an android/kernel issue than a hardware issue.
I have noticed that I get the corrupt sdcard error everytime I try to use the "mass storage" or "media device" setting with Windows.
I use Ubuntu 99% of the time and leave it connected in "camera" mode, have never had that pop up like that...
I usually just use ADB to copy everything anyway so I do not miss the "mass storage" mode at all.
Just had a 16gb class 10 microcenter branded card go belly up on me. Phone just all of a sudden said it was removed and now nothing seems to recognize the thing. The mount option is completely greyed out, and does the same on my note 10.1 if i pop it in there.
When your cards have gone did they completely disappear and refuse to read?

I wonder if it's the c10 cards...
You guys really shouldn't be using high class cards in a phone - there's really no benefit, as phones use SD card's very differently from camcorders or cameras...
On my ooooold phone, anything above Class6 was bad juju. I have always had class4 or lower cards, no fried cards (yet... lol)
kinda what I am feeling too. Not sure what class card I have but it was just a cheap 32gb from wallmart... Only had that error pop up once with this one though, and that was after trying to use usb storage.

Class 10 shouldn't make a difference to a device. The class/speed only comes in to play when transferring data from/to a computer, which will be faster on Class 10 vs Class 4 or 6.

As best as I can tell, thats a negative. Ive been running with a 32GB class 10 since around when the phone was released, and Ive had no issues. Quite surprising on its own, seeing as I abuse the poor thing. True that class 10 arnt useful for the phone specifically, but some shops only carry class 10 cards.
@hfase
I dont seem to have any issues with mass storage, with ~1GB written a day. Im quite curious as to why some people have this issue.

Maybe it's all down to the quality of the actual card itself?
Perhaps the cheaper no-name / off-name brands have a much higher failure rate....?
I'm not really sure, short of actual hardware issues on the device.
AW: Your SD card likely isn't the problem
Well here is my experience:
I am using a new san disk 32GB class10 micro sdcard. It was never format ed/ used before. The q itself formated the disk.
I have had no problems until using the twisted asanti prebuild
Version. Since then I only got problems with the qu saying the sdcard would be corrupt, after reboot. ( I expected some additional wired things, like the currents widget, which I deleted before reboot reappeared). So I would suggest it is an error in un mounting the sdcard before shutdown, which causes this failure.
Since I usually do not reboot the phone expect for flashing new roms, I had no trouble since then.
Hope this might help to further circle the problem, and maybe find a solution for this.

Since CM10 I haven't noticed any SD-Card issues, but I have the feeling, that there are some issues, which aren't detected.
In the last few days my CM10 was acting weird.
1. The gallery (together with the camera app, 2in1 app) disappeared in the App Drawer (was still in /system/app) and didn't appear again after overwriting gallery2.apk again.
2. The Google Weather App had a graphical issue, so I was sure, that there was a flash issue by restoring ASA14 and flashing CM10 (from SD-Card!).
I solved this issue in copying the nandroid backup and CM10 to the phone and flash it from there.
I have tested my SD-Card in my external cardreader, it had no issues in doing so.
My guess is, that the SD-Card needs more power than the Photon Q can give and is losing some read/write commands.

I've used better Samsung and Sandisk cards and have had this issue. It just randomly wipes all my data and creates the LOST.DIR with it all in there, but file names are all renamed and would takes years to sort through and try to figure out what is what. All my photos, music, etc.. were basically gone then. It didn't matter that the card was a name-brand or not. I've had the issue with several cards.
I constantly have this problem as well, and I've found that mounting the SD card with a reader or in another phone in a Linux environment fixes it for the most part. I think files still get lost, but you get most of what you had back.
I got a 32GB UHS1 card last week and it hasn't had a problem.
My SD card gets corrupted every time I reboot my phone. I'm using a 32GB Sandisk Ultra formatted as FAT32. The phone has CleanROM 5.6 installed (I've wiped, redownloaded, and reinstalled the ROM a couple of times).
Any ideas or experience?
Probably going bad. Mine did similar things when it was going bad. I formatted and did every trick I could find online many times to see if I could get it to work, nothing worked.
I ended up getting it replaced by SanDisk. Pretty easy to work with and I got it back within 7 business days.
I keep all my roms and zips on my internal and do not flash anything on my sd card.

Does the card work anywhere else? I had a Sandisk Ultra UHS-1 Class 10 go bad in mine as well. Some of the research I did I found out it was a common inssue with those kinds of cards, especially if they were exFat because of the way Samsung uses their own proprietary exFat system.
I've done a large write+verify using it in an SD card slot on a laptop and it worked fine. The card is only about a week old, and it's done this since the beginning. I don't expect Sandisk would replace it since it works fine in Windows but not my phone.
They should replace it. Mine was mounting and unmounting over and over again. They didn't have any problem replacing it. No reason not to call. The only downside is a no or if they say yes, you will be without the card for about 7 days.

If it's only been 7 days, take it back to the store or order a new one and then send this one back. That being said... I've had 3 32GB sandisks go bad in my phone, to the point of even being corrupt in Windows. I'm using a 64GB now, and knock on wood, it's been working fine for about 2 months so far... There have been a few threads about cards going bad in these S3's. Dunno if it's just coincidence or what.
I bought it from Amazon and have done a lot of returns there lately, so I contacted Sandisk. They agreed right away to replace it, so I'll do that.
Thanks for the suggestions.
Did you buy it online? If so it might be fake. Read more by googling fake micro sd. Apparently they make a 1gb memory card look like 32. It will just overwrite itself making data corrupt
Had the same issue with the same card. For me it was a hardware issue. When the card is inserted it clicks and comes back out a little. On my phone it came out a little too much and was losing connection with the card over and over and telling me the card was corrupted. All I did was push the card back in until there was resistance from the locking mechanism. Haven't had an issue since.
Now I say it's a phone hardware issue but really it could be that the card is too short or the cut outs where the locking mechanism holds on to are too low.

I got it direct from Amazon, and it held and verified 30 GB of data with no problem. It's definitely real.
