All very interesting, the fact is that a hard drive is a physical |
2 |
medium and the magnetic field is very malleable. It is very possible |
3 |
to recover the data even if some random trash has been written over |
4 |
it. The way hard drives use elaborate algorithyms to 'guess' the |
5 |
contents with huge accuracy suggests that any approach is possible. |
6 |
This one reason why real security experts run multiple ie 14 passes at |
7 |
least with random data and very likely use Electromagnets of extreme |
8 |
power to reduce the chance of data recovery. |

While the practicality is not there to recover data that has been |
11 |
overwritten a couple of times is economically untennable, I'm sure the |
12 |
NSA can do it if it really wanted your data, of course you would have |
13 |
to REALLY PISS THEM OFF to force their hand. Data recovery firms |
14 |
could do it if you paid them enough. |
