That explains how the police are able to reconstruct illegal data from your harddrive, even if you think you've deleted it. |
Actually, even if you write all 0's to the memory, the police can still recover what is there due to magnitic history if they have the write tools. To truely erase something, you have to follow the NSA standards which are something like Write 1's, Write 0's, (repeat 3x) then some alternating 1/0 thing and repeat, finally end with all 0's.
