Is there a quicker way to protect my data when I give the drives away,
other than smashing the drives to bits?
If you don't have state secrets on your hard drive and you don't expect
that the NSA will be using million dollar equipment to scan your drive,
a single pass with "dd if=/dev/urandom of=/dev/sdx bs=1M" should be
sufficient and will write at the max speed of the hard drive.
