spinrite claims to make the head do other things than what the drive firmware |
33 |
makes it do. Meaning that spinrite can extract data that the drive itself in |
34 |
normal conditions cannot. This reasoning is sound. |
35 |
|
36 |
Remember that a drive is an analogue device, not a digital one (only the |
37 |
*output data* is digital). |
38 |
|

There is some doubt as to whether spinrite can even function in this wise with |
40 |
modern drives though. |
