    I am "nukin" a 60GB IDE hard drive from a used laptop to prevent the Russian from obtainin my outrageous high score on Tetris when I sell the HD.

    I am using DBAN and chose DOD (7-pass). The throughput rate
    is only 2.7MB/s?! Why so slow? :confused:

    Should I let this continue (need 72hrs???!!) or should I pull the battery out?

    Seems kind of slow.

    Any idea if this is a normal throughput rate? Or is this sub-normal?

    I honestly couldn't tell you but IDE drives have slower throughput than SATA though, you should be getting more than that though. couldn't you use a windows install disc and just use the format function on that a few times for similar results?

    Anyone else think this is a slow throughput rate or can offer some explanation? Thanx

    It sounds about right... I used DBAN on my IDE drive and did about the same amount of passes, and it took over 30hrs. The drive was only 30GB so...... your 72 hours seems like in the ballpark with a 60GB drive.

    A normal write speed is what, 30MB/s on a laptop drive? You're writing 7 times, so of course the throughput goes down.

    But all you're really doing is killing the useful life of the drive. Just zero the sucker out... even pro drive companies can't recover that. There was the " great zero challenge" some guys ran for a year with a couple thousand as a bounty if anyone could recover stuff from a simply zero'd drive. Any company, anybody. Nobody even took them up on the offer. On a modern drive, you simply can't recover overwritten data.

    ...... Unless you have a set of factory test equipment. Which the Black Hats certainly do. But for Us Normal Folk, a single pass of DoD wiping plus a full reload from recovery disks is plenty.

    I was nuking a box at work today, getting 47 mb/s, so yeah I think that is a little low. These computers are over 3 years old as well, 80 gig drives. I use the Guttman wipe though, maybe it is different depending on method used?

    Wow that's pretty quick. It's in the 3rd pass. I guess I will let it run thru
    the whole 7 pass. :cool:

    I just left it, it was only on the 7th pass of 35, takes about 8 hours for an 80 gig drive. Was 16 hours on the last two but they were relics... lol
