Discs with 6-second index 02

Describe the bug
I have a case of a CD that displays C2 errors on sectors 300-307 and 320-327. This disc has a index 02 of as long as 6 seconds, and the sectors with C2 errors do not have any files (this is what CDMage claims), which leads us to assume that these errors are in the index 01. Could these be mastering errors or unidentified protection?

This disc has a index 02 of as long as 6 seconds

LBA 450 to 525. It seems it's intentional.

the sectors with C2 errors do not have any files (this is what CDMage claims), which leads us to assume that these errors are in the index 01

LBA 299 to 1498 are mode 2 but no EDC (Other sectors are mode 2 form 1). It seems it's also intentional.

Could these be mastering errors or unidentified protection?

I'm not sure but it may be a protection.
Protection list is here -> https://www.cdmediaworld.com/hardware/cdrom/cd_protections.shtml

Or "A-Ray Scanner", which is copy protect detection tool, may be useful.

Hmm, it looks like neither A-Ray, ProtectionID nor BOS detects protection on this CD. Mastering errors?

Liga Polska Manager 2000

Same publisher game list: https://www.mobygames.com/company/4673/marksoft/games/
Same developer game list: https://www.mobygames.com/company/20701/mgroup/games/

Maybe there is a title with the same protection( or error).

I have a question. Does the /sk option allow skipping more than 2 sectors? If not, would you add such an option? I want to be able to enter a range of sectors to be skipped, e.g. 300-307, instead of entering each sector individually.

 LBA[000300, 0x0012c] Detected C2 error "00 F0 F0 F0 00 00 00 0F 0F 0F 00"
This error can't be fixed by plextor drive. Needs to dump it by non-plextor drive and replace it

Do you have ASUS/LG drive that can read the lead-out sector?

Unfortunately, my BW-16D1HT with firmware 3.10 modded by RibShark is also unable to read this sector and reports a C2 error in it

saramibreak · Answer 9 · Thu Oct 19 2023 01:22:23 GMT+0800 (China Standard Time)

If possible, upload 3.10 logs plz.
If you have NOT modded drive (BW-16D1HT 3.02 etc), test it plz.

2. I will try to test it on my BH16NS40

3.10 and BH16NS40 output similar result.
LBA 300 ... 367 always output the same hash -> intentional error?
It seems that other sectors are real error.

This problem looks like "Eikan wa kimi ni 3" of the FM Towns. http://forum.redump.org/topic/32047/fm-towns-disc-c2-error/

What if it was possible to set the /sk option so that I could skip more than 2 sectors and that I could use this option to set 2 sector ranges (300-307 and 320-327) and I could dump these sectors in a drive that would somehow read them (at least and swapping disc method)?

saramibreak · Answer 14 · Fri Oct 20 2023 20:50:37 GMT+0800 (China Standard Time)

300-307 and 320-327 are readable sectors. I'm not sure that these sectors are really protected, so I don't skip reading. /sk is used for unreadable sector (e.g. laserlock).

MrPepka · Answer 15 · Fri Oct 20 2023 22:37:41 GMT+0800 (China Standard Time)

These sectors are probably not protected, but what I mean is that I want to dump the disc in DIC on Plextor, but skipping sectors 300-307 and 320-237. I want to read the sectors that I have indicated on another drive (GSA-H10N? H20N? Any drive that will read these sectors without errors) and then import them to the image created in DIC. Oh, that's right. While we're on the subject. The merge option you once implemented still works?

You dump the 300...307 and 320...327 sectors by any drive using date command.

DiscImageCreator.exe data <driveletter> 300to307.bin <drivespeed> 300 307

DiscImageCreator.exe data <driveletter> 320to327.bin <drivespeed> 320 327

And merge these files into "LPM2000".

DiscImageCreator.exe merge LPM2000.bin 300to307.bin

DiscImageCreator.exe merge LPM2000.bin 320to327.bin

As a result, 300...307 and 320...327 sectors with c2 error in LPM2000.bin are replaced by these non c2 error sectors.

Could you look at the logs from BW-16D1HT? It seems that this drive doesn't like it when a disc with audio tracks has C2 errors, we had a similar problem here - #236 (comment)
