So as I've read, usbStorage isn't really a folder. The weird thing is, I copied some files to the usbStorage folder 'successfully' at work. Well, it didn't give me any errors while copying the files anyway.
Before copying I checked if I had enough storage space because I had to copy a couple hundred MB's worth of wav files. When I got home there was nothing there which, as I know now, was to be expected.
The problem is I DID lose the storage space... How am I ever getting that free space back!? Can't very well delete non-existent files.. Confused :S
Some extra info: Running WanamLite 10, custom rom, rooted ICS.
Thanks for reading,
Rajiv
What are you expecting to happen? The usbStorage folder is for USB OTG (i.e. something plugged into the micro USB port, like a memory stick or hard drive), nothing else.
Uhm, yeah. I've read that.. After encountering this problem, obviously.
So what was I expecting? Regular folder behavior of course..
What I would have expected to happen, knowing what I do now, is an error message along the lines of not being able to write to that particular folder.
Neither happened though and now I'm missing a couple hundred MB of storage space... Any ideas on that?
Not having had this problem before, I would copy all folders on to a PC, format the SD card then copy the folders back in.
Might want to copy the folders over one by one.
Edit: have you checked to see how large you 'lost.dir' folder is? Long pressing on any folder then selecting details will show you the size of that folder.
I regularly delete the entire folder. I deleted it for a friend last week. His was 2.4gb worth.

After upgrading to ICS, some of my apps stopped to work. At first I tought the problem is with how ICS handles external_sd folder on internal memory. Than I noticed that I cant copy anything from my PC to Phone via cable. Strange thing is that I can copy via kiss air. So, I am in doubt where could be the problem:
1) ICS ?
2) Cable ?
3) Phone memory ?
4) Phone usb jack ?
Since I don't have second cable with me, I ll have to investigate after few days, but would like to hear your opinions. I just tried - copying from phone to pc via cable works fine. Last evening I updated Kies on last version. Also, I formated usb of the phone - no change - still can't copy anything on the phone.
***
Update - now it seems that I can't copy anything on usbStorage folder only !!!

Thanks in advance.

do a factory reset and install phone drivers fresh ...
So, situation is like this:
even on the phone, I cant copy anything in folder usbstorage. So, it looks like internal usb is damaged ? Also, what is strange, I CAN copy a lot of data on the phone, but note in folder USBSTORAGE or, for example external_sd (i don't have real sd card), which is probably internally made in usbstorage folder ?!? But I can copy more than one gig of data from pc to phone, and when I go to settings of the phone, I see that amount of free usb memory is decreasing, and internal phone memory is same.
very strange.
Looking for your answers.
Zile
Stop copying things to the usbStorage folder. It is only for USB OTG.
As said above try reading the basics first from the stickies .

My Igo stopped working. All the data was stored in external_sd. Now, when i try to reinstall, simple it doesnt wotk again. So thats the main reason i wanted to access these folders. On Gb everything worked fine. Now on Ics - not.

I've highlighted another problem for you.
Just to clear some things: I didn't have real sd cart. I suppose that becasue of missing sd card, some of the software i use on GB was making folder external_sd somewhere on internal memory of my SGSII - probably software is design to work that way. Folder external_sd could be seen using es file explorer, but not with default file manager. Also, on GB, I was able to copy files on folder usbstorage. On ICS - not any more. I admit i am not expert for android, but i aks: why on GB it was OK to copy files in this folder, now it isn't any more with ICS ? It makes me think that something is wrong with my phone. Or with ICS ? If this folder was provided to be just for "USB OTG" (whatever it means) - why I was alloud (as common user) to copy files in it while using GB ? I don't want to be software geek, I want to use my phone in the consistent way. Imagine that you have a PC, and on winxp you can copy files in folder MyDocuments, and for example on Windows7 you cant any more becasue iyt is now only for "DOC OTG". And, just to inform you - problem solved. I had to make folder on root of internal memory. After that software recognized it a put everythig in it.
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).
HI
I took the 32gb memory card out of my old HTC Desire HD and put it into my new S3.
Very strange because although the directory structure appears, the file explorer reports that every directory is empty - which they aren't.
The storage statistics correctly tells me that the memory card is almost full - so why won't it read the files?
I think that's the same thing as what happened to me today. No idea why it happened, but the SD contents showed up correctly after rebooting my phone.
Thanks.
Comforting to know that it isn't only me. However I rebooted the phone but no change.
Sounds like a formatting problem. You might have to copy the data off to a computer using a card reader or the old phone then reformat the card using the gs3 before putting your data back on the card.

Yes, I think that must be the explanation. What a nuisance.
I'll try it and report back. Ta
Well it is very wierd.
I formatted the sdcard both on the PC and also in the phone.
Despite this, the file explorer still reports the file structure - which now no longer exists.
I've rebooted the phone. Makes no difference.
Phantom file structure reported on the phones file explorer - even though the available storage size is correct in the storage stats.
Does the computer also report the phantom file system?
This seems really strange indeed.
Have you tried writing new files to the card on the gs3 then see if they show up in the computer?
Sent from my LG-P920 using xda premium
No. The computer shows correctly.
But now - even more wierd, I downloaded a lot of files to the phone's internal memory.
Although the SDcard is empty, the phone's file explorere now shows the SDcard as containing the files.
My head is spinning.
I wonder if this is at all related to my issue (http://forum.xda-developers.com/showthread.php?t=1698672). I also experienced a phantom file structure, but it only affected a few hundred picture and music files (out of several thousand).
Thanks for this suggestion.
I don't think that the issue is the same. It was never formated exFAT and also there is no trace of the files at all.
When the car is inserted back into the HTC there is no problem. When it is in the PC - no problem.
I have now tried with another card - 16gb. Same thing.
These are good quality cards which have been used for more than a year on other phones.
I'm starting from scratch today. I'm going to reformat the 16gb using a full format - FAT32 and see what happens.
It shouldn't neeed to be this hard
Just to reiterate:-
The really puzzling things are:-
The phone's faliure to see the files - but it sees the directory structure.
The phone sees a "virtual/phantom" directory structure after an in-phone formatting
The phone sees files on the card if they have been copied there from the internal memory.
have you tried another card with the same capacity? what about reformatting the card from the phone after backing up the contents?

Yup - done all of that. No difference
what ROM are you using? are you using a custom ROM?
No. Brand new received yesterday t-mobile s3
Is it possible that the internal memory and the sdcard are being spanned in some way so that to the file explorer they all appear as one?
In fact even my Profimail email application reports that the directories and files are on the sdcard when in fact they are now on the internal memory and the sdcard is newly formatted and empty
Are you sure that you try to access your sdcard via /mnt/extSdCard/ ?
Samsung points the folder /sdcard/ to the internal memory and not to your sd card, so please make sure this isn't the problem.

Ah - that sounds like a likely possibility.
Where can I find out more about this pelase.
Is there a way that I can point it at the physical card.
I really just want my phone to work in a way that I am used to and not in some wierd Samsung-controlled way
Yes, I can confirm that is what is happening.
It is really very ambiguous. ESfile explorer reports the directory structure on the external card but doesn't report the files. This is definitley a glitch which needs to be sorted out.
It also means that if you use windows file explorer to upload data directly on to the external card, it doesn't seem to be accessible to the phone.
Surely this can't be right
My S2 has just got a really big problem for 2 days. I can access the internal storage (which is 11Gb) and see or copy all the files to my laptop's HDD. But the problem is that I can't edit any of those files (by using apps in the phone).
When I tried to delete some files, it told me those files is deleted but they're still there, unchanged. When I tried to create a new folder, it said "Creation Failed". The same things just happened on every file manager apps I've ever used. :crying:
Moreover, I can't access gallery now, it said "Not enough space. Delete unnecessary items..." although I have 6 free Gb in my internal storage.
I'm pretty frustrated now. Any ideas would be highly appreciated
There is really no helps
Rooted?
Rom?
Maybe install/flash again
Hi guys, a colleague at work asked me to move photographs of her late father from phone memory to SD so she can take them to get printed. So I plugged the phone in via USB, cut the images (which I now regret not just copying) and pasted them in the DCIM folder on the SD card. Seemed to do the job. No errors or anything.
10 minutes later she returns, and tell me they have vanished. I just thought they wouldnt be showing in Gallery for some reason but when I plugged the phone in via USB the folder was completely empty. I am baffled and obviously feel awful about losing the photos.
I've tried an app called Rescan SD but to no avail. Anyone have any ideas on how I could get these back or why they disappeared in the first place?
Thanks
As to why they disappeared, that's anyone's guess. Try Recuva (Google it), might get them back (tell her to back stuff up in future if it's important as well).
Edit - Re: why they disappeared, seems after you cut them something caused the contents of the clipboard to be deleted outright. Normally in Windoze if you abort a cut/copy>paste, whatever it is you were trying to move stays put in its original location/is untouched. Obviously that didn't happen in this instance. Whether that was an outright Windoze barf or whether there was a transient issue with connectivity between the phone & PC that caused it to barf badly enough to 'lose the files in transit' perhaps, is open to conjecture.
Was it seen in the gallery before it vanished?
Its a file transfer issue.If you are connected with mtp mode,always copy the files to destination instead of cut feature.And if you copy a file from source-close the source- and then paste it in destination,the copy won't be successful.Source window has to be opened while the paste function is pressed.You can,however,cancel the window while its progressing.
If the files were seen in the SD card and then it vanished ,it might indicate that the card is faulty.Try any file recovery software ,the process time to recover files depends on your system config.
All the best.
