Let say I use Eraser (or other tools) to erase my hard drive (using DoD standards which is 7 times or Gutmann which is 35 times),
These eraser tools just write random data on the hard drive many times correct?
Also if encryption looks like random data, how can anyone say its encrypted or not without you confessing?
If I were to erase one of my hard drives now, so I can sell it without anyone snooping on it easily, and the authorities seized my computer and told me to decrypt the hard drive… Well, I can't!
What I'm asking is, do TrueCrypt volumes look like random data?
