That method doesn't work with negative offsets because the "garbage" you would see is actually the last part of the last data sector, in scrambled form, which gets pushed into the audio track precisely because of the positive offset. If the offset is negative you can't see it because it's actually inside the data track, so even if you try to go back one more sector the drive auto-corrects the offset and doesn't let you see the raw, uncorrected data.

There are alternative methods, though; you can still use the audio swap trick or the D8 command (if your drive is compatible with it).

Interesting thread. Use Plextools....hmm....point me to a guide / thread please. I have a Plextor drive, but can't dump some discs with EAC. (Read, doesn't match the Perfect rip dump)

Now that the audio tracks are properly ripped, I got one last question:

Is dumping the whole disc with DDump and extracting the first track (via Extract From-To: Length) from the image with IsoBuster a proper solution for a mixed mode SafeDisc CD?

That was a hell of a work. Someone should write a tutorial for SafeDisc + Mixed Mode. Image Also some of the information here should be put in the official Mixed Mode tutorial, so people know why they are doing what they are doing.
