a single pass is doable but from someone who has been working with computers for as long as I have then being in the e-waste business and knowing where some of the hard drives go...Dod wipe is best.
I know people who sell hard drives to countries that really should not haven them, they don't want the drives for the metal but for the data and they have the gear to do it and very low labor costs.
Data theft from hard drives has been on the rise and is only going to get worse when higher end computers that can work faster and the amount of data that COULD be on a hard drive from credit cards to bank info and a persons SS and just about everything else and who knows who elses info is on the same hard drive (family owned computer) its worth it to them to spend the time...
P.s why do you think companies in the last year to two years don't want there drives "refubed" and want them shredded ON SITE?
my 2 cents but we dod everything....setup 10 (or more computers) hook up 3 to 6 drives and leave them. Use a KVM switch and run all computers from one station. You can get the larger ones used for servers on the cheap.
