Description

When dumping on an ASUS BW-16D1HT, some sectors are incorrectly "successfully" retried. This is most easy to notice with SafeDisc protected discs, I'm not currently sure if/how it applies to other protections or legitimate read issues. The dump goes as expected at first, with the expected slowdown during the protected range, and with the errors being trimmed afterwards. Once the dump reaches the "retry sectors" stage, every single sector is correctly retried. Due to this, instead of the sectors being 00 filled, they appear to be full of some kind of garbage data. It appears to me to be some kind of drive caching FW issue, where certain attempts at rereading result in garbage data being returned. Especially suspect to me is that the individual sectors are not successfully read during the "trim" stage, only in the "retry" stage. I also verified that my PX-760A dumped the disc as expected, meaning that this is drive issue. Confirmed on FW versions 3.02 and 3.10.

Exact command line used

aaru m dump D: Sweet3.aaruf

Expected behavior

The disc to have unreadable sectors due to SafeDisc.

Actual behavior

All the intentionally bad sectors are incorrectly "correctly retried".

Issue still present on newest current commit of devel branch 82f2fd6.

TheRogueArchivist avatar Jun 26 '22 03:06 TheRogueArchivist

I can reproduce this on an ASUS BW-16D1HT as well, using both 6.0.0alpha9 and a self-compiled binary as of https://github.com/aaru-dps/Aaru/commit/4825d414604fe30e23ceabc169be94f1b0dcd781

I'm able to trigger this bug on a disc with intentionally bad sectors (ring protection), during the re-reads, it fixes the sector even if they report media errors in the first run.

I agree with @TheRogueArchivist that this is likely a cache issue.

I can somewhat replicate this issue with this drive (tested 3.02, 3.10 and 3.10 with RipShark mod) on redumper as well:

The problem is that starting from LBA 1080, the disc contains a ring protection that doesn't even carry a sync signal, so the drive shouldn't be able to read any data from it at all.

I am not sure if this is the exact same issue though since redumper uses BE_CDDA on this drive.
