for the 2nd time I can not open the files inside the card. They are not even shown in the screen. But they are there as when I go to memory, 1 GB is used.
same problem, haven't been able to figure it out. I'm defecting to a blackberry, this is too much of a hassle

Which cards are you using ? Brand, size, format etc
Having asked that, I'm on Sandisk 16Gb SDHC for about 4 weeks now, having evolved from the Sandisk 8Gb variety.
Up till today, I would have sworn by Sandisk - no hassles at all for over two years.
Then today the 16Gb card corrupted. To be fair, there were warning signs for a few days previous (programs not loading correctly, the device hesitating on save, and so on), but I didn't diagnose a corrupting card as the issue as I've had no problems with them for so long.
Recovered now, re-formatted the offending card (FAT32).
My view at this stage is that it was caused by a program Card Studio. This seemed a brilliant diagnostic at the time, as it announced it found rogue clusters on scan and repaired the card. Small footrpint, quite fast scanning.
But soon after replacing the card with a new, unused one, Card Studio announced in fractured English that the 2 FAT copies on the new card didn't match. So I re-scanned with Pocket Mechanic as a check before letting Card Studio "repair" it.
Repeated scans with PM found no problems and the card is working perfectly.
I suppose one may draw certain preliminary conclusions here.
It's a sandisk 4gb sdhc
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?

Just curious, as I am about to be on my 3rd card. First two cards, transfered for a short period of time, then froze, then reformatted, same thing. Next time reformatting froze, and both cards showed unsupported file structure.
Used:
Dban
sdformatter
diskpart
gparted
linux fedora built in formatter
os x disk utility
fdisk
and everytime the card fails to format. I did call sandisk who told me their class 10 64gb microsd cards have had a really high fail rate...
I was on the phone with them asking why I should keep the card...lol
i am not angry, just really curious if I am the only one. Would be my Irish luck!

I've had my SanDisk 64 Gb card and GSIII for a whopping 8 days.
No problems yet, I filled up 50 gigs on the card and no errors of freeze ups (I haven't transferred anything into the card since the day I got it)
I'll let you know if it kicks out on me.

mine was immediate. First card I got 12 of 24gb transfered crashed, second card was 6gb of 24 before it crashed.
they are overnighting me a 3rd card, so i prolly will get it thursday, and will try again...
I purchased the 64Gb Class 6 over a month ago and have had no problems. I was bummed I did not go with the class 10, now hearing the high failure rate on the class 10 makes me glad I got the class 6.
Thats wierd, mine has worked flawless so far. Keeping my fingers crossed lol.

I didn't think there was even a class 6 for sandisk's 64gb SDXC? One doesn't exist on their website anyways. I had even bought one off bestbuy advertised as the class 6 version, but when it showed up it was the class 10(possibly UHC too, threw the package out so I'm not 100% sure on that part)

My mistake, you are right. I actually meant between the two versions of the 64GB, the cheaper (non-UHS?) one.
I had a Class 10 64GB Sandisk card fail on me but it was plugged in to the computer via USB at the time so I don't blame it on the Galaxy S3. They sent me a Class 6 card in return. When pressed on it they said they have been having problems with the Class 10 cards and their technicians are looking in to it. After dealing with Sandisk customer service for a week, they finally agreed to send me a Class 10 card after I send back the Class 6 one.
So that means I'll be without an external sdcard for another 3 weeks! Total time I have been dealing with this issue is 4 weeks so far.
The Galaxy S III format function will only format for extfat32 which is Microsoft proprietary and not fully understood by Samsung or others. Its a known issue now that it causes corruption and missing files on the Galaxy S III. ROMs will also not support the formatting, you need to format Fat32 using a tool. I'm not sure if it could lead to permanent damage though as described in OP.

there are plenty of people using the card in exfat, as many have stated they stuck the card right in the SIII and off they went.
also, plugging the card right into my computer, and never into my phone, led to the same issue.
also mentioned, calling sandisk, they said their is a high failure rate on the class 10 cards. Those of you with cards still working, I hope my new card coming in tomorrow, works the same way.

If you do still want to get your old one working (if you still have it), I guess you can try this utility. It worked for me when I messed up some of my old cards pretty badly. Perhaps it is worth a shot?

have that listed in my OP, didn't work on either card. If I ran it on the card normally, would tell me the card was write protected. If I ran it on the card after using gparted to delete the main partition it would get about 40% through formatting and then fail saying the card stopped reading.
Sandisk cards really are junk & it's not just the 64 gig class 10.
I have used their cards for years as there is not a lot of other options at times, but I had three of their 32 gig cards go bad on me.
I now have three 64 gig class 10's but I back them up religiously to my PC. I don't use FAT32 as I store blue-ray rips to my card that are over 4 gigs & FAT32 won't allow that.
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.

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.

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?

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 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.
