Going to excess old laptops and I have to attest that all data is gone. Thus KillDisk and I are getting acquainted again. Some drives will only take about 45 minutes.... others of the same size will take 3 hours. Don't understand why since drive geometry is identical.

Not going to have any data on those puppies when they get farmed out to some elementary school. Wish I could install Suse on them before they go out.
