I recently attempted to set up an encrypted TrueCrypt folder (non-hidden) on my USB Flash Drive. Before doing anything I copied all the files on the USB to my computer's harddrive. I then deleted everything on the flash drive, set up a TrueCrypt file on the drive (the file was 3.5Gb out of the 4Gb available), mounted the TrueCrypt file, and copied all the files from my computer back into that file. Everything seemed fine - it took a couple of minutes to move all the data into the TrueCrypt file on the drive, and I saw all the files were in the folder once the data had been moved. However, I did not look into each file folder to check that every subfolder had been moved, etc. I unmounted the virtual file, remounted it, and found that nothing could actually be opened and everything had a size of "Zero". By this time, however, I had stupidly deleted the original backup on my computer... So my data may be lost forever.
I'm curious if this is something that anyone else has encountered and whether there is any way to access the data again. I know the password and I'm fairly certain the files were moved at some point - perhaps they were deleted or something is wrong with the file system. Regardless, any help would be appreciated.
