Hello.
I bought a 1TB drive and I'm planning on doing DD on it. It's a WD, so I guess using a Seagate disk to wipe is not recommended.
What does it take? (what commands), How long? Does doing it very often hurts the drive? (my old 320GB drive had +4000 reallocated sectors)
All I'm used to do is:
* Erase the partition table with $sudo dd if=/dev/urandom of=/dev/sda count=1
* Create random size partitions with random file systems
* Delete all partitions
* Erase the partition table again and then create the partitions I needed.
Are those above enough, let's say, in a virus case, a bootloader virus or a MBR virus? WHY and in what cases are DD needed besides selling the drive? How is data recoverable? Can the FBI recover it?
Currently my partitions are:
- 320GB for Windows, used ONLY for games, nothing pirated
- 40GB for /
- 571GB for /home, encrypted.
Thanks in advance.
