I couldn't get dban to work so I'm using Minitool Partition Wizard Disc Wipe on a 5tb drive doing a 0s and 1s pass and it's only moved 1% in an hour. I didn't think it would take more than 7 or 8 hours. Is it safe to cancel and do it again only writing 0s instead? (Which is claims is faster). I want to be able to sell the hard drive after. Not sure if I also need to format it for it to be readable when it's done.
