There seems to be a bug if a disc has two data tracks.

When dumping No One Can Stop Mr. Domino, the second track has a different crc32 even though sectors and size matched.

His Track02 is a data track and it has 32 scrambled bytes at the end where other programs have it filled with zeroes. Somehow there must be a problem with descrambling (I guess that 32 bytes = +8 samples is the combined offset) or splitting the tracks.

I dumped a disc with R-W filled with FF, and it was suffering the very slow reading speed.

Please tell me a title.

Is the tool supporting C2 error reporting? Would be nice if it did.

I want to know main, sub c2 read order. It can confirm by a perfectrip. PX755A is main+c2+sub,

I have not yet tried to dump some discs with intentional errors (safedisc, laserlok, smarte, sector header)

I haven't these disc at present.

Please upload sub & log & Track2 data.

Take any CD image with the .sub, then replace all the zeroes in R-W channels with 0xFF instead of usual zeroes (you can use R2WFill.exe tool for that), then burn it and try to dump with any tool - it will be slow. AFAIK it's not caused by the dumping tools, but by the drive's firmware.

Contains the .sub, .sub.txt, and .log.txt.

Hope you can see what's wrong

So only in 100b mode? maybe because of the Reed Solomon checking?

As far I know, it is always main+c2+sub, except for Mediatek drives (main+sub+c2).

According to Carlos (IpseDixit), R-W filled with 0xFF pattern is nonsense data which confuses the drive's logic which performs the 100b mode:

Also,

Code: Select all

SCSI bus status codes:02-CHECK_CONDITION [F:ReadTOCText][L:1815]
Sense data, Key:Asc:Ascq:05:24:00(ILLEGAL_REQUEST. INVALID FIELD IN CDB)

.

Weird, works for me. Cannonfodder has two data tracks. existing dumps are wrong? Can anyone explain how to dump those with isobuster or other tool? So I can compare.

Just dump the two data tracks glued in a go. Then use the remove program to split the dump into data track 1 and data track 2, according to subcode info.

Maybe you can help me with this if I post the image in bin / cue format? You also need the sub file from subdump?

[pablogm123]

Just run the Extract from-to function to dump the entire disc and post the dump 7zipped. And yes, sub file is required.
