Heh.  It'll stop when the disk is full.

Sure.  Actually, my preferred method using Unix/Linux is something like

  dd if=/dev/zero bs=1GB of=/dev/<device>

tuning 'bs' to the device and how much you're going to overwrite.  You
can limit this using 'count=X'.

'Course, these days I just drop the disk on my Diskology DriveJockey and
tell it to wipe it.
