I have this 16 GB USb Flash Drive and I remember storing a lot of data in it. I used this several weeks later on my Windows PC and it fails to show any files on it. None were hidden and even so, my PC has showing hidden folder options enabled. It seems to occupy 9.8 GB at least.
I'm now using this from an ubuntu desktop and it's the same. It's FAT32.
I always made sure to eject safely but it happened anyway.
I'm afraid to make changes to the drive fearing it will overwrite existing data (in case the file system screws up). Are there any file recovery method that will help, for Ubuntu?
