I use dban (see dban.org) but - caution - that wipes all the harddrives in
a computer, though.

On a recently refurbished ex-Windows XP tower with two 250GB drives a
matter of hours for one drive and weeks for the other drive. I went ahead
and the second drive speeded up enough to do a full wipe on the faster
drive and a single wipe on the slower drive.

HTH,


Ian
