Brute Force -- A piece of software that tries Username/ Password combinations at random until it finds the right ones.

File Corruption
Easily fixed with $50 software
Deletion

Recuva.com is a very good free tool
Secure deletion makes files unrecoverable
Stop using the computer if you accidentally delete a file.
Physical Damage
