Deleting HDD

I want to random data overwipe my HDD several times, to be leet.

Any programs you'd recommend?

shred

Darik's Boot and Nuke or Autoclave (though the latter is not updated/supported any more).

Here's a list:

Pick one that's GNU (NOT shareware, if you're on windows that's important), and go for it.

Yeah, try C, Python, PHP (CLI SAPI), Perl, Ruby, ...

I wrote my own wiping script, because I'm leet, or because I like to waste time.

A wiping script would be trivially simple:
#!/bin/sh

cat /dev/urandom > /dev/hda1 but it wouldn't sufficiently erase the magnetic traces left on your hard disk that can be used to recover your child p^H^H^H^H^H^H^H sensitive data.

dd would be a better bet. Just because it isnt cat.

That's a crap wiping, I clear with 01, then 10 to fuck up magnetics as much as possible, then two passes of random stuff, then for regular files, I rename them to something random of the same length to wipe hints in the directory before deleting it.

You're right, I must have been tired when I wrote that.
