/sf doesn't seem to skip dummy sectors on PS2 unlicensed discs anymore.

Not sure when this change would have occurred, but dumping these sectors is very slow.

Here are the logs of 3 dump attempts. First two I cancelled the dump at the end, it tries to reread c2 sectors despite /sf. 3rd dump is run with /c2 0 /sf but has to many errors.

Here another dump of same disc on old DIC 20211101T132455

Tested with test build, I think it is still wrong?

sarami, your github README mentions that 4824 is not good for "Securom 3"

Protected CD:

• SecuRom 3
  
  • PLEXTOR PX-4824A (ecc/edc of the 2 sector doesn't match)
• CDS100, CDS200, Label Gate, XCP
  
  • PLEXTOR PX-4824A (doesn't get the TOC correctly)

Which particular discs did you encounter that had issues? I have not encountered any yet.

Also, regarding CDS100/CDS200/Label Gate/XCP, using the Full TOC works with the 4824 to get matching hashes. And only XCP1 has illegal TOC (retail XCP discs use XCP2 which does not have an illegal TOC, 4824 has no problems with them).

Diablo II (USA) (Play Disc). Serial is S7092920. If it's dumped by PX-755, it's no error. But this may be a problem with my PX-4824.

It's TOC that I mention, not FULL TOC. But if Full TOC gets LBAs correctly, I'll change from TOC to FULL TOC in the future.

I dumped Diablo II (Korea) (Play Disc) just fine with my 4824 https://redump.info/disc/119191/

Yes I can confirm that the 4824 does get the wrong TOC for Label Gate and CDS200, splitting the scram into bin with --force-qtoc on redumper fixes it.
However the Full TOC shouldn't be used by default, redump uses TOC splits.
