I'm repurposing a computer that has sensitive data so I need to secure erase it. The hard drive is encrypted by TrueCrypt. I started decrypting it, but TrueCrypt is saying it's going to take 4 hours. I'm impatient. Can I skip decrypting and just secure erase it or is decrypting necessary?

P.S. - I don't want the drive encrypted in it's next iteration.
