Re: Wiping hard drive before selling
I imagine if you used dd to write /dev/random to the entire drive (sda, not sda#) and then /dev/zero over that it would probably be difficult to impossible for someone to get any meaningful data from the drive even with special hardware. But just writing /dev/zero to the entire drive would make it appear to be totally empty with no partitions to any OS or data recovery program.
