Forum was getting a little bogged down with a few issues so I thought I would start a problem specific thread. I have transferred files (music and movies) to my 16gb micro SD. All the music is there, but every mp4 and avi file is gone. The only solution I can think of is to insert the card when I need it and removing when done. I love this tablet and the vegan beta 4 rocks. Much thanks to the hard work. I was curious if anyone has a solution to the sd card issue? It seems like it was happening on multiple roms.
Seems videos are lost during SD card scanning. What worked for me was create a ". nomedia" file in the root directory of sdcard2. Haven't lost any since.
Will try that. Thanks.

I tried creating the .nomedia file and it seems to have done the trick. My video files are not disappearing anymore. Thanks!

Question to Viewsonic:
Is this by design or is it just another problem?
I've got the same problem on my Htc Flyer.
How have I to create this file ?
has to be the name just like "aa.nomedia" ? Did I understand well ?

No, it's actually a file named ".nomedia" nothing else. You can use notepad++ on your PC to create it, or a file explorer on the device. You don't need any text in the file at all, just a blank file called .nomedia
Most instructions state to put it on the root of the SD card, but I took it an extra step and put it in every directory including the root...just to be safe, ya know
I'm using a GS3 w/ a Sandisk 64GB microSDXC card formatted as exFAT. I'm hoping someone here with knowledge of exFAT can help me troubleshoot an issue I've seen. This is probably going to end up fairly detailed, so bear with me.
I recently copied ~40GB of data to my new 64GB card in Windows using the card reader in my laptop. It appeared to go off without a hitch. Today, however, I noticed an issue with my music files (mostly .mp3 and .wma). I had transferred a new song to the card and it seemed to go through. However, on the device, the file didn't appear. So I did it again, transferred the file, and it seemed to go through. It didn't tell me there was a duplicate file on the device either, so I played it on the card through Windows to test it. No issues. Unplug my device and the file disappeared again.
So I go into ES File Explorer (and later I used the My Files application that Samsung loads, with the same results) and go into my music folder to see what's going on. It appeared that at some point, the file name got corrupted and concatenated with part of another file name; instead of being "artist - song.wma", it was "artist - song.wmas Track).wma". So I think that the OS doesn't like the .wma in there, and try to rename it to what it should've been. The system says that that the file system already exists. I tried to delete the file, and it won't let me. The file explorer is also reporting that the file is 0kb in size. At this point, I open up a terminal emulator and try to delete the offending file through the command line, but I cannot delete/rename the here either, despite being listed (I'm told the file does not exist). Finally, I plugged in back into my Windows box but the bad files will not even show. The file on my computer is good and plays fine.
So I scratched my head for a little while. Then tonight at the gym I wasn't able to find the song I wanted. Sure enough, it was tied to this issue. I went back into the file explorer and found ~50 files (of ~4200) that had corrupted file extensions. These differed from the original in that only the file extension had been altered (ie .mp3p3 or .wmaa). However, I am unable to delete/rename any of the files. Also worth nothing is that some of these files had sizes. It's possible that other files exist like the original where the file extension is valid, but the original file extension is within the file name.
I have not confirmed this yet, but it is also possible that the issue is not limited to music files. I was looking through my pictures the other day and noticed that some images weren't loading; I deleted these files at the time and didn't think anything of it because a few weeks back my epic 4g corrupted my microSD and I had used some file carving tools to recover some images (obviously, not a perfect fix).
So the problem is beyond my expertise at this point. I'm not sure how to handle these damaged file remnants. I'd like to get rid of them because they prevent the existence of the good file in that particular folder in addition to taking up space. As a short-term solution I re-copied the files I wanted to a temporary folder on the card and they are working without issue.
Right now I'm leaning towards wiping the card, reformatting it, and transferring again. However, before I do that, does anyone have any ideas? Is there any chance this could be an issue with the card itself? Or a GS3 issue? The files on the computer are still good and the problem seems to manifest itself regardless of the method used to transfer to the card as the original files were transferred using an SD adapter and card reader, and the file that triggered this issue was transferred using the usb cable.
I appreciate any insight or opinions.
Tim
it's caused by long/speciafic filename of the file.
just put the sdcard into your cardreader and then connect to your pc, delete/rename the file which caused the issue.
The files don't appear for me to be able to delete them. The file explorers won't allow me to delete them. A terminal lists the file but tells me it doesn't exist when I try to delete it.
UPDATE: I formatted my memory card using the device itself and transferred the files again. This did not resolve the issue. Interestingly, the SAME files that were corrupted last time were corrupted this time. I can still transfer the same files from my computer to a separate folder and they work. The file remnants cannot be deleted or altered. What could be causing this issue?
Is this a genuine card? I once bought a 16 GB memory card that was actually just 2 GB but reported the full 16 GB to Windows. I found out I had been scammed when I started getting errors similar to yours when I copied more than 2 GB of data.

I'll give it a shot when I have more time, but I'm leaning towards a software issue. It's either an issue with the file system itself, or with the SGS3 software. The same files are corrupted in the same way each time (in the same folder). However, in the new folder where I moved the copies of the problem files, there were also some corruption, but different from the original folder. Moved new copies to a third folder, some files were good, a few more remained corrupted. By the time I moved copies into a fourth folder, there were no more issues. The problem is now I probably have an extra 500MB+ worth of garbage that I can't do anything with. The search for the underlying issue continues...

try formatting in the device, then transfer over one of the files and see if it has a problem....I would guess the file name of the problem file is too long. if the file transfers and is still a problem try renaming it to like test.mp3 and see if it transfers ok.

I thought exFat had really large limits on filenames? That, along with the greater than 2gb file limit removal, are some of the pluses of this over regular Fat. I could be way outta line here, but that's what I remember about it. ExFat should rock! FWIW, I've had a Kingston hyperX flash drive formatted with ExFat and have never had a filename issue copying 10's of thousands of .mp3's, .jpg's, etc...
The files in question don't have particularly long names though. I'm guessing that there's a small handful of files elsewhere on the folder with a name that's causing the file system to freak out. I'm curious if tag info or metadata could cause an issue as well. This last time I transferred via sub directly to the device instead of taking the card out and using a card reader. My next move might be to transfer via the reader and see if there are any issues BEFORE putting the card in the device; it might still be a sgs3 issue...
Not sure if you have tried this yet but since it seems to be repeatable by way of the same files, have you tried copying the offending files to internal storage to see if the same problem occurs?
This would definitely rule out the MicroSD card and lend itself towards being a software issue.
SOLUTION: Format the microSDXC card as FAT32. All my files transfer, show up, and work just fine. Either the exFAT file system is broken, or (more likely) Samsung broke the exFAT support somehow. I might experiment with exFAT on an 32GB card to see if I can find the root of the issue, but for now I've lost my patience.

My Sandisk MicroSDXC 64GB card should be arriving today. I was hoping to use exFAT so will try it out tonight and report back. I have lots of HD TV shows to transfer so it will be full straight away.
Hi there
I also got the SanDisk 64GB SDXC card in my SGS3 and it is formatted as exFat. I think this exFat does not run correctly on the Galaxy.
I also encountered some corrupt file names on the SDcard and even some of my music folders do not show up as folders but as an unknown file that cannot be accessed.
Furthermore I copied some .flac files to my phone. The files work without a problem when being put on the internal storage. As soon as I put them on the SDCard the stock-music player does not recognize the .flac format anymore and thus the music cannot be played.
I guess I will re-format the SDcard to FAT and hope that Samsung (or maybe even a DEV) will come up with a solution to this problem. Another positiv aspect of having the card formatted as FAT is that I probably can apply some custom kernels and they will mount my FAT-64GB card (currently the custom kernels cannot mount or detect exFat formatted drives).
Hope this info helps a bit.
Working perfectly for a couple of week now in my S3, formatted exFAT.
I tried my Sandisk 64GB exFAT card last night and all seems to be working perfectly, I have filled it and can see all the files on the S3. Very happy with it.
Not Stable exFAT
Looks like exFAT is not yet fully finished in SGS3, thats why Samsung didn't include information about exFAT on their manual / user info.
When i use exFAT format, the problem is almost non existent in few file, but when i filled the SD card with many data and lot of small files (ex. HD Game data), the card says corrupted in my SGS3.
Screenshot is in here : LINK
The problem is only exist when the sdcard is start to filled with many files.
But when i filled it with few file but large size (ex. 4 files of *.mkv, that totals to 42GB), the card runs fine.
So the problem is only exist if the sdcard is filled with many data.
Please all of you try this, if my problem can be repeated in every SGS3, then it is definetely bug from the exFAT support on SGS3.
*also has tried it with siyahkernel that listed have exFAT support, but the problem is still the same in that kernel, maybe the support/patch/mod of exFAT that gokhanmoral use is the same that come with our stock SGS3.
Mine if near full, lots of app and game installs and small files and no problems here.

hmm.. maybe its different firmware that causes it ?, mine on XXALE8-DXLE8
My SDcard is filled with Tintin HD game data, and that makes my exFAT SD card to show corrupted on SGS3, but normal on everything else (computer, laptop).
I have my ATT version SGS3 loaded with a 64GB microSD card and used iSyncr to transfer my entire library of about 13,000 songs from iTunes to the card (about 55 GB) on an Win 7 PC, including playlists.
Problem - When I call up a music player, it seems that about 200 songs are missing. If I look in file manager on the phone itself, I can see a bunch of files with zero size and a 1969 last modified date. I assumed they just got corrupted in the transfer. But when I plug my phone into my PC as a media device and look at Windows Explorer, I can only see the just some of the first artists folders (the ones that start with A and B) and none of the rest of them, even though the rest ARE visable on the phone though file manager and the music player. To further confuse the issue, when I take out my microSD card and plug it directly into the comoputer WITHOUT my phone, I see everything, AND the same files that have zero size in the file manager on the phone are perfectly fine on the card!
I'm sure this is just some issue with the "Mediastore" corruption (.e. ICS references all "real" media files by creating a shortcut entry in it's "mediastore" and that's what it exposes to the PC and players), but when I try to clear our all the data in the mediastore (Settings->Application Manager->All->Media Storage->Clear Data) and then reboot the phone and wait an hour+ for the media store to rebuild, it did NOT solve any of the issues described.
I can reformat the card and try to start again, but I was wondering if anyone else has any ideas at all what might be going on here?
Any help would be GREATLY appreciated!!
Does anyone have any thoughts on why this might be?
If your 64GB sd card was formatted in your phone or has the out of box format which is exFat, that's your problem. Many users are finding corrupt files because of this. Format your card to Fat32 and you'll be fine.

Having similar problem with MediaMonkey and Windows Media player..
Will try FAT32 tonight.

However, data on the actual card is NOT corrupted if I read it directly in a microSD card reader. It only appears corrupted once I put it in the phone and look at it though the PC. I think it's because the Mediastore that ICS is creating is faulty, but I can't seem to clear the faulty media references.
So I don't think is a format thing. Anything else?
Still could be a exFat thing if the phone is being read through MTP.
This is a snip of what I posted in the other thread, but basically format your card to FAT32 and you can easily eliminate that problem.
Did some researching as to why Team Epic won't support exFAT. Found this page talking about how many OS's support only FAT32. Here's a link to that page: http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm There is a Windows GUI to format it to FAT32 for drives larger than 32GB: http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm

No it's not a card format thing definately.
I did the following:
1) I formatting the card to FAT32 which wiped out all the data.
2) I refreshed the mediastore on the phone, and put the card back in and re-refreshed the mediastore
3) With the mediastore showing NO media on the sd card, I reloaded all 13,000+ songs from scratch using iScyncr
4) I looked at the SD card's content with the phone still plugged into my PC without Windows Explorer and everything was there and NOT corrupted at all.
5) I unplugged my phone, rebooted it and gave mediastore about an hour to refresh itself
6) I looked at the contents on my phone using a file manager on my phone and the SAME EXACT 200 or so files were corrupted and would not play. All had a 1969 file date and showed zero size,with strange double extensions like .mp4aS.mp4aa and similar
7) I plugged back in my phone to the PC and both Kies and Windows explorer could now only see the about 10% of the content cut off alphabetically (a's and most B statting artists)
8) I took the sd card OUT of the phone and plugged it into my PC directly using a card reader. Now I could see EVERYTHING and none of the files that were listed on my phone as corrupted were actually corrupted on the card, and the file extentions were all the normal .mp4 and would play correctly
9) I put the card back in my phone and tried various music players and all could see the same number of songs which EXCLUDED the 200 corrupted songs.
10)I tried copying one of the songs directly to the card from my PC and then transferring that copied song into the correct artist folder on the phone and THEN I could see the song in the phone's file manager.
So man - I'm now TOTALLY confused!! Any ideas from anyone?
EDIT: Seems like FAT32 might be working for me.. still testing.

Doubt it. Check your NUMBER of songs between source PC and your phone after the transfer.
I think the problem is with the mediastore on the S3, or maybe the syncronizer (iSyncr in my case). I'm gonna try to sync with Tunesync instead and see what happens. I still suspect it's the mediastore corrupting some of it's media referencing when things are copied, because the actal files themselves when referenced outside the phone are NOT corrupted, just the mediastore reference to them, which is the only thing the phone let's you view (in ICS at least).
The only way to find the number of files on the phone is by looking at the directory on windows. But the number of file match
5332 files
Hey everyone,
Ever since I upgraded my phone to ICS, the memory card is not writeable and I cannot delete any files. For example, if I try uploading an album, it will show up under my player, but a few moments later it will give me an error saying that files are not found. I try deleting an mp3 track through my player or My Files and it acts like it's been deleted, but will show up again some time after.
I figured it was an incompatibility issue with the ICS OS, so I tried formatting the card through the phone and that didn't work. I tried formatting it via My Computer and even used a program called HDD Low Level Format Tool, but to no avail.
The drive is recognized by my phone and my PC and plays the music and video files on it without a problem, so I don't think it's corrupt, but it's basically useless if I can't add or remove files. I tried chatting with Samsung Support, but the guy was as useless as tits on a nun.
Any ideas?
Can you put another sd card in your phone and test it? I've had 5 out of 10 sd cards die.
Nah, I'm afraid not.
