Raw mode with /c2 is fixed.
Pack mode without /c2 is still broken.

It's not broken. LG/ASUS does not support the pack mode.

See subError.txt. Subchannel are all zero bytes.

Indeed subchannel is zeroed. So pack mode never really was supported even if a dump in this mode could be started. Fine.

Also discovered today :

- Discs with data and audio tracks cannot be dumped anymore using ribshark. DIC throws errors like this one:

Code: Select all

LBA[083296, 0x14560]: [F:ReadCDForCheckingSubRtoW][L:1283]
    Opcode: 0xbe
    ScsiStatus: 0x02 = CHECK_CONDITION
    SenseData Key-Asc-Ascq: 03-11-05 = MEDIUM_ERROR - L-EC UNCORRECTABLE ERROR
lpCmd: be, 00, 00, 01, 45, 60, 00, 00, 01, f8, 01, 00
dwBufSize: 2448

- DIC often fails to get write-offset on first attempt.

OK those issues are now fixed.

The program gets further but fails at checking subQ address for each track :

Code: Select all

LBA[088444, 0x1597c]: [F:ReadCDForCheckingSubQAdr][L:1076]

Same behavior unfortunately, though the error has changed a little :

Code: Select all

LBA[083196, 0x144fc]: [F:ReadCDForCheckingSubQAdr][L:1080]
    Opcode: 0xbe
