How to destroy data on disks?

[dmjoen]

We have just replaced a Sequent system, and I would like to destroy the data on the disks. Can anyone help me with the best way to do this? I am fairly sure that the rm command is not thorough enough.

It all depends on how secure you want to be. Personally, I use a blowtorch and a vat of acid.

Let's say I want to keep these in working condition.

Well, in that case, find that /dev entry that reflects the entire disk, then do a [tt]dd if=/dev/random of=/dev/whatever[/tt] several times. Or use /dev/null for input, or anything that will generate random data.

Install a microsoft windows based os. this almost always destroys your data..........otherwise the only way to be absolutedly sure that your data is not recoverable is to overwrite it with something else as chapter11 suggests
