I have used something like sudo dd if=/dev/urandom of=/dev/sdb bs=xxx count=yyy to write random data to non-root disks before sending them onwards. Don't use /dev/random because your system may run out of entropy and take a few years to wipe the drive. If you are paranoid, make multiple passes. If you are tin-hat paranoid (and want to protect yourself against the eventuality of a broken write wire to the disk head), create a large file on a mounted partition from /dev/urandom, write it to the drive to be wiped with dd, then read the data and ensure that it matches that which was written.
