    Standard zero-out instead of a 7-pass or 35-pass? Probably in the range of a couple hours. Could be quicker, but wouldn't expect that.

    Took me 3 hours to single pass a 500GB (5400rpm) drive.

    external USB? i think it'd be limited by the USB bus speed and dependent of the speed of the drive. along time

    edit:i did a search for read/write speeds of your drive but came up empty.... sorry :(

    How fast is your disk? At 80 MB/sec it could take about 7 hours to do 2 TB
    (! GB = 1024 MB and 1 TB = 1024 GB so 2 TB = 2.1 million MB)
