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
sufficieshred -v -n1 /dev/sdcnt and will write at the max speed of
the hard drive.
I'll give dd a try; but I don't see offhand why
dd if=/dev/urandom of=/dev/sdc bs=1M
should be quicker than what I'm using now, namely
shred -v -n1 /dev/sdc
