Cactus Data Shield discs can't be dumped properly #48

Open Feathered-Serpent opened 1 year ago

Feathered-Serpent commented 1 year ago

Hey there

I have two Audio CDs with Cactus Data Shield Protection (so Multi Session Discs), as listed e.g. from Protection ID: grafik

redumper seemingly doesn't see that:

scan started
protection: N/A
scan complete (time: 0s)

Now I'm not sure, if this protection causes the "SCSI: 0, C2: 855, Q: 322" errors, which after several (5) refine attempts don't get any less at all (I've used the loop method I've read about in https://github.com/superg/redumper/issues/36 for several rounds.) Initial there were C2: 856, Only one C2 was refined during the refine step after dump.

Here's the log file first: Wir singen Hey Ho Vol. 14.log

Cactus protection is unsupported atm, those errors are most likely coming from protection

Alright! Then I'll close the issue until something might change about Cactus Data Shield.

Actually let's keep it open here so I don't forget to work on it at some point :)

Check! Certainly won't throw away the discs any time soon, so should be able to check it at a future time again.
