badblocks is useful for this (someone else a long time ago posted a command line for badblocks that would make data on the drive truly non-recoverable). here's the command line I used: badblocks -f -t random -p 30 -sv -w /dev/ this command will take a very long time to run on any of the large >10 GB drives BUT, it will insure that no usable data of any kind remains afterward (even the NSA would have a heart attack on this). my scenario for a full wipe involves this: dd if=/dev/zero of=/dev/ && dd if=/dev/urandom of=/dev/ && badblocks -f -t random -p 30 -sv -w /dev/ that can be placed in a script and run as many times as you see fit. However, with 30 passes in the badblocks in -w mode, you can pretty much be assured that no data will exist afterward. more comments?
