Almost everyone seems to agree that recovering data from a formatted |
11 |
drive is possible. What is the process by which this is done? I've |
12 |
read here that: |
13 |
|
14 |
1. The space between tracks contains historical data information. |
15 |
|
16 |
and: |
17 |
|
18 |
2. There is a difference between a track written with a 0 and then |
19 |
overwritten with a 0 and a track written with a 1 and then overwritten |
20 |
with a 0. |
21 |
|
22 |
Are these the two processes by which this data recovery is made possible? |
