Can anyone recommended me a (preferably free) program to password protect my external hard drive? I backup everything I have to it once a week then for the rest of the time I leave it at where I work. I want to have some sort of method for preventing any of my collegues from looking at my stuff. I've been using Exlades' 'Disk Password Protection' that puts a password on the boot sector of the drive in question, but just recently I think it was the reason I lost all the data on the drive so I can't trust it any more. Any advice greatfully received!
