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

A weird issue manifested on my phone today ... the phone started, upon boot up, to spontaneously reboot. It would boot up within 30s, at which point I unlock it an pulldown the notifications screen (to see what was going on).
I saw several instances of "media scanner running" occurring - over the course of various trials I would see the following messages alternate on the top status bar.
Media scanner running... (system storage)
Media scanner running... (SD card)
Media scanner running.... (USB storage)
Media scanning completed​
...while below in the notification areas I'd see the "Media scanning", "Media scanning...USB storage" etc messages periodically appear.
The phone would first lockup, then reboot perhaps 3 out of every 4 startups. Several of those times the last message I saw prior to the lockup was Media scanner running.... (USB storage).
I pulled out the 32FB Sandisk SD card, then tried booting the phone several times, and this time no issue - booted up fine, no lockups nor auto-reboots. Note though that I've had the SD card installed for over a week, and the problem only cropped up today.
There were two SD card-related changes I'd made last night: 1) used ES File Explorer to cut/paste ~400MB of video from the onboard camera storage to the SD card and 2) copied 1.75GB of MP3 files to the SD card.
The MP3s I had copied to /media/music (direct from laptop to SD, using a microSD-to-USB adapter), while the videos (MP4s, created by GS2 camera app) were moved by ES File Explorer to /DCIM/Camera.
So at the moment my phone is working fine (4 clean boots), though sans SD card - any ideas why "media scanner" may be choking upon scanning the SD card? Should I move the SD content to a different directory, or just kill media scanner?
I've seen issues like that but usually with no name low quality SD cards, with them either bad or modified to register as larger.
I'd backup what you have on the card and format it using the phone. If it's still giving you issues try it on a computer and download a program to check the memory sectors to make sure there are no read write errors.
A good free one is ariolic diskscanner. Can't remember if it can scan SD cards though, though I'd be a little surprised if it couldn't.
You don't want to disable media scanner, not even sure if that's possible. Many things require it to be working.

thanks for the tip - I mounted the SD on my PC and backed everything up, then tried deleting the ~2GB Media directory ... no dice, still locked/booted on the first boot up. Going to next clear the other large diretory (DCIM) and see what happends, and then finally reformat the card entirely. Will report back...
so i wiped and formatted the card in the phone ... rebooted several times with the newly empty card, and so far the lock/boot issue hasn't recurred.
Copying all files save the media stuff onto the card, will repeat the test; and then finally will put the media back and see how things go; will report back.
Good deal. Hope that's the last time it gives you trouble.

This is so weird. I've had this problem as of yesterday.
I'm having the exact same issue... but with a Galaxy S 4G.
I tried re-flashing my phone but I realized it was the SD card causing the problem because the internal phone storage scans just fine.
I've tried 2 different SD cards (one Samsung, one Kingston) - backed up my files on my Mac and tried formatting both cards, putting the files back on the SD cards and booted the phone.
Same problem was happening.
The phone boots up fine without the SD card but I am at loss what to do considering most of the apps I use need the SD card to run.
Try formatting them using the phone.
Could be a corrupted file on your SD card. If after the format the phone works fine, put the files back on one at a time and see if that's what's messing it up.
Try also changing the format type. Seems androids like fat32 a little better.

so far so good ... went a day w/o any spontaneous reboots, thought I do want to do a few more startup trials, but fwiw, formatting the SD card (in the phone) seems to have done the trick.
I do realize now that when I first inserted the card in the phone, I just started using it, I didn't bother formatting it - doh!

I have this same issue -- when my MiscroSD card is in, and it goes to media scan, the phone just keeps resetting... SO annoying
question: how do I format the external SD ?

Same problem on Samsung Galaxy Ace
I'm experiencing the exactly same problem on my rooted Samsung Galaxy Ace (Gingerbread 2.3.6).
Reboots with SD card mounted and working fine with SD card unmounted.
I'm using Link2SD with a 2nd ext2 partition, and when SD card is unmounted, all Linked apps work perfectly fine.
I've tried removing and re-inserting SD card and also recreating mount scripts to no use.
What might be the possible causes of this problem???:crying:
Please help :fingers-crossed:
Hello,
I bought my Galaxy S II a few days ago. One of the first things I did was rooting it. Then I proceeded to install some apps, and getting my music on the phone. I downloaded Winamp Pro, since I use Winamp on my computer. So I copied my music folder to an external SD card (I have 6,1 GB of music, and I don't want it on the internal memory). The folder structure is a Music folder with bands, and inside the folder I have another folder called Soundtrack, for, well, my soundtracks.
So I putted the folder on the SD (since Winamp wasn't syncing with my device), and it worked great. Then I installed some more apps, and for an unknown reason, my SD became corrupted, so I formated it, and put the musics on it again. But since them the music aren't being recognized. After the format, Winamp found the device, and I used it to transfer the musics. But halfway trough I realized that he as putting the artists and albums in different folders, so I stopped it, and deleted the folders. I put the musics manually, but every time I opened Winamp, or the stock music player, It was only seeing the musics that were on the folders before I deleted them, and also it was showing a Samsung album and a (I think it's was this name) sound album. I them installed CF-Root kernel trough Mobile ODIN, and flashed MIUI through CWM. The MIUI player was having the same problems.
Now, I searched a lot, here and on Google, but nothing worked. I tried:
Putting the musics on the internal Music folder
Searching for a .nomedia folder
Searching by folder (The musics are there, but when I select any of them they don't play)
Filter by Folder on MIUI player (There's no folders to thick, it just shows a pop-up asking to select folders, and an Ok and Cancel button)
Rescan, trough a Media Scanning App
Selecting another folder on MIUI player (Can't do that either. The first time I opened the folder view, there was a list of musics, but it disappeared after a second.)
Changing the folder name
Clearing the data and cache for both apps (Winamp and MIUI)
And I restarted the phone after every single procedure
I think I didn't forget anything.
But anyway, that's it. I have music in both folder (internal and external SD) now, and none of the Players are recognizing the music.
So what I have to do?
Thanks,
Hexagono.
Try with a single file first make sure it is a MP3 that actually plays .
Put it on the phone via cut and paste to internal sd card ..
Open My Files app navigate to that MP3 and open it ..
Check MIU actually has a working music player .
That fails i would wipe phone and flash stock firmware .

Ok.
I put a single music on the root of the internal Music folder.
Winamp, not recognized it. But it played the song when I chose it by Folder. (And didn1t display the album art (which happens every time I chose something by folder))
MIUI Player, didn't recognize it, an it didn't display on the folders view (Which, correct me if I'm wrong, doesn't have an option to browse trough the folders.)
MIUI File Explorer crashes on opening.
So, flashing stock? Or I can re-flash MIUI?

This REALLY sounds like you either have a .nomedia file floating around, or need to format your internal memory (aka USB Storage), as it may have corrupt memory sectors. I'd copy everything from internal memory (/sdcard), format your USB storage, copy it back. If it's still doing this, scour your files for a .nomedia file more carefully.

I search for .nomedia, and found some, but that didn't solved the problem.
So I copied everything and formates. This time I decided to try something else, and I putted the musics on /external_sd, which worked.
So that kinda solves my problem. The only thing is that I want the music on my SD, not on the internal (I putted two songs. One in external_sd and another on the I: drive (Which is my SD drive). Only the one on external_sd showed up).
But thanks anyway. At least I'm able to listen to music now.

Seems you're confused.
/sdcard/external_sd is the sd card you plug in.
/sdcard is the phone's "internal" memory. It is what is left of the included 16gb of the phone memory after System memory, App space, and the OS.

But the files I put on /external_sd doesn't show up at the I: drive.
And also, I take my words back. With one song it recognized. but with the whole library not.
EDIT: More test, more strange.
So I've putted 3 songs. One I put in I:/Music and one I put in H:/external_sd/Music, and one on both.
The song I've putted on both get recognized, it plays, and show the album art. The one in external_sd, virtually exact like the one I but in both (the only notable difference is that the bit rate of this one is 3 less than to one on both) is recognized, but it don't play (MIUI says that the file type is not supported, and the file type is the same as the one i put in both) and doesn't show the album art. The one I've putted only on I:/Music, does not show up.
EDIT 2: This is creepy.
So now I put the song that wasn't working in I:/Music and it magically works. And the one I've putted only on I:/Music, still does not show up.

The letter "I:" means nothing to me; on my current computer, my phone maps to "E:" and "G:". ("F:" is already taken by a network drive)
/sdcard and /sdcard/external_sd both map to drive letters. Is "I:" the first one, or second one mapped when you plug your phone in and turn on USB storage mode?
If it's the first one, then "I:" will be /sdcard. If it's the second one, then "I:" will be /sdcard/external_sd.
So if your drives map to "I:" and "J:", then "I:" will be /sdcard. But if they map to "H:" and "I:", then "I:" will be /sdcard/external_sd.
Make sense?
EDIT: I see what you're doing. You're putting stuff in H:/external_sd. Don't do that. I: is your external_sd

That is correct. H: is internal, and I: is SD card.
But as you can see, the music apparently only works if the file is both on the H:/external_sd/Music folder AND the I:/Music folder.

No offense, but I can't see. This is happening on your phone. I have 8 gb of mp3 files on my external sd card, and they're only in one place. And I happily listen to them just fine, with album art and everything. So I'm not quite sure what is happening on your phone.
EDIT: for example; E: for me is internal memory, and G: is the external sd card.
E:/external_sd is COMPLETELY BLANK for me. It says there is nothing in there.
G:/music has all my mp3s.
So I'm not sure what is going on with your phone, but this is how it should work.
For you, H:/external_sd is intended to be a virtual mapping. You shouldn't be dropping files in there. Any files you want on the external sd card should be going into I:

Yeah. Thanks anyway.
And I expected that it should be a virtual mapping. When I use Super Manager (Since Root Explorer crashes) to go trough the folders, when I go to external_sd it goes to the external SD and I can see the files there. It makes absolutely no sense that the music players aren't seeing the files.
EDIT:
So I downloaded PowerAmp, and it recognizes the music. The problem is with MIUI Player, and Winamp.
EDIT 2:
So I woke up this morning, after putting the rest of the music, and re-scanned with Power Amp. Them, everything worked. -.-
There's a problem with the ID tag (Some music from the same albums are showing as a different album) and the album art is really low quality. But I can listen to music now!
Thanks to ctomgee and JJEgan.
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
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.
