    1-4 minutes in normal mode. A Zero, about 4 hours or more if you're on USB2. You didn't mention which bus (FW or USB)

    4 days? Even USB 2.0 shouldn't take that long. Are you running it through a USB 1.0 hub, by any chance?

    Did you do a simple erase? Or did you set it to overwrite the disk? If you set it to overwrite the disk and did selected more than 1 pass you're wasting your time.

    Wise words.

    After a single wipe pass, it's very unlikely the CIA could recover any useful data off a modern drive. Let alone some random criminal. The multi-pass wipe options are completely unnecessary these days.

    If I were that concerned about hiding some data, I'd just destroy the drive.

    A safe option certainly. But not a financially rewarding one because smashed up drives don't sell for much.
