So in case of this 1024B sector is DIC going to have support for this?

Sarami: Could you made a commit to git with latest changes? I think I have a DVD that fails to dump and I'd like to debug it...

Another weird bug. 2nd track misdetected as audio. The dump is correct, the 2nd track is properly descrambled, but the cuesheet is wrong.

Maybe there's something unusual with the disc itself, because the older TruRip db dump is totally broken, with the incorrect total image size (16 sectors smaller than should be) and incorrect sizes for most of the tracks. Subs are normal, all the 2nd track's sectors are marked as 41 02 (data).

Yes, path/directory table can read correctly.

Fixed a transfer length for reading Volume Descriptor of DVD. Concerning committing, plz wait...

Another weird bug. 2nd track misdetected as audio.

Code: Select all

     Combined Offset(Byte) -30576, (Samples) -7644
    -   Drive Offset(Byte)    120, (Samples)    30
    ----------------------------------------------
           CD Offset(Byte) -30696, (Samples) -7674
    Overread sector: -14

Sector size "-14" is incorrect. "-13" is correct. This is fixed but I don't know whether the misdetecting is fixed or not.

Sarami, if you are looking for a challenging protection, get yorself this or this disc.

https://www.medimops.de/infogrames-der- … 6FS55.html

This one from the same publisher has the same protection:

https://www.medimops.de/vivendi-univers … edVeryGood

The process took 18 hours to complete because about 35% of the CD contains unreadable errors!

I bought Fort Boyard Millenium. There are some errors in CDDA area. Is this true?  Jackal, usurper, if you have this, plz check...


EDIT:
20170728
- added: /ss option (scan sector for protectCD-VOB)
- changed: Option name is /rc -> /sf (scan file)
- changed: Directory record size from 8192 to 16384
- changed: Data sector is descrambled when sync is valid and mode is valid
           and there is the reverted sector, and unknown mode but reserved byte all zero
- changed: The LBA of FULL TOC is used only the multi session disc.
- fixed: Reading path/directory record (support the logical block size under 2048 byte)
- fixed: The transfer length to read path/directory record for DVD
- fixed: Short of the shifted sector if the combined offset is 2352*n (n is integer)

Trying to dump a CD-i game (Dimo's Quest).

It seems that the offset is misdetected, which results in a dump with shifted data that is missing 3816 bytes in the first sectors.

What is also strange, is that when I do a normal sector view in IsoBuster with the Plextor, there is an offset in the data sectors. The Optiarc drive does not have this.

The old px_d8 tool detects the combined offset correctly as -924. The dump should match this other disc(which also matches Trurip) - https://redump.info/disc/35804/

Is this a drive bug or a software bug?

https://redump.info/disc/36178/ This disc is perhaps same.
These discs have only audio track on TOC, but there are actually some data sector in pregap of first sector. When dic searches the offset from disc, it gets the offset from "first data track". So dic can't get it properly. Why wouldn't CD-i adopt the mixed (data - audio) disc?
Please wait until fix.

EDIT:
Updated test version. Please test.

[Jackal]

The new test version dumps the disc correctly, thanks!

Jaguar discs are also interesting in terms of offset detection

So,
I try to dump a dvd-video "Biohazard 5th Anniversary - Wesker's Report (Japanese)" using a usb drive.
It's my first dump so I don't know what is wrong.
Could you explain if my dump is ok or not? Also could you explain about the options /c and /f in dvd dump?
First I played for couple of minutes with vlc and then use DIC.
