I bought a 32 gb micro sd off ebay! I've heard of some people getting bad cards off there. The one I've got is a Sandisk 32 gb class 4.
I've been able to do these things:
-It reads 30.9 gb available space after formatting it.
-Format it from the phone.
-Move my apps to it and they function fine.
- record video and take pictures and view from the phone.
Now when it comes to putting MP4 movies on it, I've been able to get 3 to work. Any others I put on it it either won't read them or the video doesn't play right. I have a class 2 16 gb sandisk that has no problems at all.
My questions are these. How do I know if I got a fake one, is there a way to test it? Are there any ideas on a way to fix this?
I'm running a 32gb class 4 card in my phone with no problems.
Are you saying that the <i>same files</i> work on the 16gb card, but not the 32gb card? I'm having a hard time with that idea; the card doesn't care what the file is; its only job is to store the bits.
It is possible that you're hitting a bad spot on the chip, and that the larger video files happen to be the ones hitting the bad spot, but I've never actually heard of an SD card that "sort of" works; every one I've ever had has either worked or not worked.
If you're having trouble with video files in general, the problem is more likely the encoding of the video files. If you're trying to view downloaded movies, you could be hitting unsupported resolutions, bit rates, or encoding schemes. There also seems to be a wide variation in h.264 encoders, so some will work great and others will fail miserably.
One thing you could do is find an encoder that works for you, then run any movies you acquire through that encoder to ensure that you have a uniform resolution, bit rate, and h.264 encoding setting.

Hey Tom thanks for helping OP out. Regarding the 32gb card, how much did you pay for it? I was looking in amazon and they are 45 dollars. Did you find a better deal?

30.9 gb sounds right. The rest of the card is dedicated to storing a map of where the files are stored.
If you think the video files are corrupted, try playing them on your computer from the card.....they should work. In that case you just have a funky file that isn't working in your phone.
Moboplayer is my favorite media player, if it needs any extra codecs to work, it'll let you know. Just make sure to change the video decoding to "software" after that, I believe.

What are you guys using to get all of the files transferred from an old card to the new card, I have formatted it on the phone, on the computer, tried copying from the computer to the card using a USB adapter, tried copying over the same way but in 3 separate batches, The phone is seeing the card and 26G free, but none of my programs are showing up. I am now trying this, formatted the card in the phone, and copying through the phone.

I just used a card reader and copied the files onto the computer then from my computer to the new card. Also i think it was a bogus card. The guy offered a full refund but now that he got it back, I havent heard from him. I filed a buyer protection claim. I read a n article in ebay forums about bogus 32 gb cards being sold. They're only 2 or 4 gig cards made to look like 32's. Anyone else heard of this?

my htc hd7 driving me crazy and i tried many roms but still the same problem after 5 or 7 days of flashing the new rom my phone suddenly do a hard reset i lost many pictures and many other because of this can any one help me plz
Sounds very much like a hardware bug. I'd get the phone replaced under warranty if I were you.
Are you flashing stock ROMs or custom ones? The custom ones may be less stable than the stock, but you shouldn't be having the problem you describe anyhow. Does anybody else have access to the phone? It's entirely possible for kids to accidentlaly hard-reset the phone; it takes a little effort but less than you might think.
i flash custom roms and no one touch the except me and my phone warranty expired
It's entirely possible that the custom ROMs are buggy, and even slightly possible that they damaged the phone somehow (not likely, but possible). Have you tried flashing a stock ROM and seeing if the problem continues? Be aware that it will overwrite HSPL if you do so, but it's easier to re-unlock the bootloader than handle constant hard resets.
If that doesn't fix the problem, you're probably SOL. I've not heard of anybody else experiencing what you describe unless it was a hardware problem. I guess you could try opening up the phone (it's tricky but totally possible, especially if you don't mind voiding your already-expired warranty) and re-seating the internal microSD card.
i opened the phone and re-seated the sd card now i must wait 5 days
if it reset again i will try to flash it with the stock rom
I hope that helps! Sorry I can't offer more advice (except to search for anybody else who has had this problem). My HD7 has stayed perfectly stable without a single unexpected hard-reset, so I can't help you from experience.
Have you changed the stock sd card to a higher capacity/different sd card at some point?
This could be the cause, if the card is not 100% compatible/fast enough etc. After 5-7 days of use the memory card could reach a point where it has certaint level of data and the problems start.
EDIT: Asking because you so nonchalantly told you opened the phone and re-seated the sd card, kind of gave me the impression you did it before?

hhh yes i did it before to change the sd card from 16gb to 8gb class 2
i noticed that if i put the phone in my pocket it became too warm from the down back side maybe this is the cause of the problem
and it get very hot if i put it in charge too
The class 2 card is too slow, stock is class 4. Putting too slow card in the phone can cause all sorts of problems.
I changed on my HTC 7 Pro from SanDisk 8gb class 4 card to SanDisk16 class 2. After 4 days or so it started to cause resets and after little more time programs wouldnt run anymore etc.
Now I ordered a Samsung 32gb class 10 that people all seem to have good results. It was 32eur delivered. The phone is wayyyyyyyyyyyyyy faster and no more problems at all. I installed it a week ago.
What I read its not only the class either, some cards seem to have compatibility issues also. This Samsung card seems to be working for everyone, but there are more choises.
The "class" rating on SD cards is a rough measure of their sequential read and write speeds. This is important for things like cameras, which need to rapidly write a lot of data in a smooth sequence. The phone needs a certain amount of this, but not much - Class 4 cards are about as slow as you can buy today, and will do just fine. What the phone does need is extremely fast random access. Many SD cards, especially "high-speed" ones, actually perform relatively poorly in this regard. It's generally not tested for, either, so even within the same brand of card individual chips may vary.
Im sure whats above is correct, I dont know much about the tech side of this.
However Im pretty sure the OP's problems are due to the sd change.
The thing for me and what Ive read for others too, is that the problems do not start right after change of the card, everything looks normal for a while.
yes every looked normal in the first week but before this class 2 8gb sandisk card i tried a normal card calss 4 16gb and it didn't work

I don't suppose you have a link for this Samsung card do you ? I'm a bit wary of buying SD cards due to all the problems with compatibility and fakes.

Well I know about the fake cards, specially on eBay. I bought from eBay , German seller, member since 99 and sells a lot of memory.
The seller seems to have raised the price for the card little since I purchased, I paid 27,90+shipping. (he had +10 sold at that point, now 40)
Here is the link for that :http://www.ebay.de/itm/180835219519.
EDIT: The price seems to be at the right ballpark for this card. I saw similar price (discounted) for the same card on some store link posted here at XDA. It was some of the topics regarding memory upgrade on WP7 device (most likely at HD7 or HTC 7 Pro section).

Im using Ansar's lates rom btw. When I started to have problems with the old card I didnt flash a new rom, just changed the card and did a hard reset... Tomorrow I think it will be 2 weeks with this new card, no weird behaviour at all.
i changed my memory to sandisk 16 gb calss 4 and now my phone reset and restart many times a day omg i can't find the samsung calss 10 in my town and i can't buy from ebay
There are other cards that work too. You can find more info about cards here: http://forum.xda-developers.com/showthread.php?t=883582

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...)

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.

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

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?

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.

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.

I think This may have hit the nail on the head. I have had a couple cheap discount cards die but they really died. Cant even read in the PC and one even got really hot when plugged in. Got a good branded card from amazon and havent had a problem since.

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.
