unfortunately I have acquired a new Sandisk m320 (512MB), I copied some files there, played them, deleted some, added others and it ended up in a very weird state.
After deleting all the files, there is no way to copy more that 300 MB of data in there because the disk is full. Apparently there are some files which are not visible but use the remaining 200 MB.
If the device had a reset button to delete all the files and left it as it was in the factory I would be able to fully utilize it.
I have used any file browser under windows and unix with no success. I have not formatted the device because I'm afraid it will die after.
These devices are unreliable, undocumented and lack of good technical support. If only I had known ....
Any idea ?
Re: Unable to delete files and recover unused space
This actually sounds a lot like the problem pointed out in 'can't delete songs on sansa m230', and I'll bet it's got the same solution (you can read my full explanation there, but I'll just give the gist of it here).
The Sansa has two USB settings, 'Auto Detect' and 'MSC'; for some reason songs put on it through MSC aren't visible from the computer if it connects later using 'Auto Detect', and vice-versa. As such, try switching the USB setting from one to the other and see if that helps.
If it doesn't then I don't know, but my guess is that it will. ^_^;

Hi, Since I was facing the problem when I connected my memory card to the system and accidentally deleted my photos in memory card and came across the recovery software to recover data from memory card and here is download link
If the pen drive is working, the data is there and can be recovered. I
think it could be due to virus activity. Some virus make the contents
of the drive hidden, thats why user can't see the files and the space
available for use is less than the capacity. It is suggested that go
to FOLDER OPTIONS - and select SHOW HIDDEN FILES. It may show the
hidden files. Otherwise, you can use any data recovery program to recover the data. Please not that you should not sav/write any data to avoid overwriting the existing data.
try a hard drive recovery program,like partition magic or hirens repair disk,some flash drives need to be formated in fat16.not fat32,or ntfs,your computer cant do that,but the right software can,good luck hope this helps
When a file is delete, it's still there on the drive, just as before; all that happens is that the file table marks it as free space and changes its name so it's no longer visible. There are a number of "undelete" utilities available, including several good ones, like asoftech data recovery that helped me before: http://www.asoftech.com/adr/
I had a similar problem, I could upload songs, but they wouldn't play and I couldn't delete them.
turned out it was cause I didn't have WMP10 installed on my PC, had an older version.
the user manual states it only works with WMP10, and after I installed it (just search for windows media player 10 on the microsoft website) I was able to use the synch function in WMP10 and all the songs are playable (I'm listening to an album as I type :D)
