I'd welcome Joel's views, but I don't think you should apply what he said about SSDs directly to flash (USB) drives. The technology is similar, but there are significant differences; I don't think that USB drives typically have the over-provisioning found in SSDs, and they certainly have smaller block sizes. As far as I know, doing a free space erase on a USB stick will make all the deleted files on it non-recoverable, though it may not remove all the file names.nesinsula said:Will it work to just format the whole USB stick? Or could someone still easily recover data from it?
Try it and see . Using a file recovery program is the best way for an ordinary user to test an erase.nesinsula said:On my MP3 player i have recovering software, will it work?
If you are clearing the drive completely, I would format it first (if there is a 'quick format' option, that will be fine), then erase the free (that is, all the) space with Eraser. On a flash drive, erasing the files directly will not work.nesinsula said:OK, so i should use eraser to remove all the files and free space?
And it will not work to use the formatting (sorry i said "recovery" in the first post) software/firmware(?) on my MP3 player instead?
In principle, no. But the point to bear in mind is that Windows has to see your MP3 player as a drive, and how it does so will be a function of the player's firmware.nesinsula said:Thanks for your answers. If i use eraser to erase all the free space on my MP3 player, is there a risk of removing the MP3 players software/firmware?
