Dear David,

GNU coreutils has a tool for this; it's probably preinstalled already.
A typical command might be:
sudo unmount /dev/sdx && sudo shred --verbose --zero /dev/sdx
where /dev/sdx is the path of the device to wipe.
This will write three passes of random data onto the hard drive, as well
as a final pass of zeros to make it appear as if the hard drive never
had any data on it. If they have a capacity of, say, 500GB, it will
probably take a day to complete: it may be worth doing them concurrently
if your PC has enough SATA ports.
I would personally run this on a live OS, without any storage devices
attached to the PC except the ones to wipe. One can never be too
cautious when using this command - you did want something irreversible,
didn't you? :)
Best wishes,
Sebastian
