Some luck on some more sectors for ASUS BW-16D1HT ?

I tested this drive a bit now, it's not really good at C2 errors, I think it caches and doesn't ever re-read. Could you look into that sarami?

Set C2 for 0xf1 of ASUS BW-16D1HT

Last secotor is half scrambled ? Mastering error or bad dump ?

Half scrambled. Perhaps Mastering error.

Failed to get read offset with ASUS drive. Logs attached for ASUS and plextor.

Sync is weird. I can't fix it.

An unlicensed PS2 disc. I'm dumping it multiple times, and sometimes hashes match each other as different sets of matches.

sarami, please take a look and let me know what you think https://drive.google.com/file/d/1WgFt2I … sp=sharing

Inconsistent, but again the hashes are familiar https://drive.google.com/file/d/1u9mveY … sp=sharing

Unlicensed PS2 disc has intentional C2 errors like safedisc. Safedisc has sync + msf + mode but unlicensed PS2 disc hasn't it.

Do we know what the pattern really is? For that and for safedisc?

Usually /sf flag works. I've dumped tons of ps2 UNL consistently that way. But this disc keeps producing a handful of hashes, a couple of which keep popping up over and over. These gamepro discs are a little different. Silver bottom and a raised ring in the ringcode area.
