Try "shred". It's part of the GNU fileutils, and should be present on
your system. You'll probably want to shred the entire device, e.g.
shred /dev/hdc
You could also use alternating dd passes, provided you had an all-ones
source to go with /dev/zero. /dev/urandom might do in a pinch. I
wouldn't depend on shredding at the file level; the man page indicates
that file system behaviors may not produce the desired result.
If you're running OpenBSD, FreeBSD or NetBSD you can also use "rm -P",
apparently.
