[thelist] Linux diskwipe tool?

[spinhead]

We have a couple dozen 9 gig ide drives with RH Linux on them, filled with
proprietary data. Is there a viable diskwipe utility (can run from Windows
or Linux, we don't care) which will reliably clear the disks? I have to be
able to sell the idea to some pretty savvy upper management. The only other
option is to lock these drives up. We'd prefer to re-use them.

Thanks
