This sounds like more what I had in mind... there is no worry about |
18 |
making data irrecoverable. I'll check this out... booting the |
19 |
hardware with a liveCD of some sort that I know has that tool on it. |
20 |
SystemrescueCD probabably has it. |

This may be all I really need. I had considered it to start but had |
36 |
the notion that it might not be that hard to return a disk to its new |
37 |
condition ... apparently that is not really all that easy or in this |
38 |
case ... even necessary. |
39 |
|
40 |
I've googled fairly extensively on the subject and did not find a way |
41 |
described anywhere to return a disk to what is called its raw state. |
42 |
Or, put another way, the state a disk is in why you buy one new. |
43 |
|
44 |
There may even be legal ramifications I suppose along the line of |
45 |
selling used discs as new after some kind of processing. |
