So you know all about the CDB's, Sense Area data and stuff then? Ok, fair enough.
Here's the one Windows 7's erase disc feature sends to the drive:
CDB: a1 11 00 00 00 00 00 00 00 00 00 00
and here's ImgBurn's one:
CDB: a1 11 00 00 00 00 00 00 00 00 00 00
Now, if you can see a difference between them that I'm missing, please do tell.
