sarami - any chance you could add functionality to DIC to transform dense.bin to a proper Track 03.bin?

Contact themabus if he still lives or use gd command of DIC.

themabus i've tried to contact many times to release the source code - no reply

Disc Image Creator is no good for gd dumping, always fails https://drive.google.com/file/d/1X6EDSD … sp=sharing

My kreon drive is no problem.

sarami,
There is a CD-TEXT DIC issue I want to report.
Due to CD-TEXT space limitations (stored in R-W subchannel), sometimes they use TAB symbol "\t" ASCII and "\t\t" WIDE to refer to previous non-empty text, this is not implemented in DIC, thus such fields have spaces instead.
Example: https://redump.info/disc/87491/

There are more things that I have to report but I'll do that a little bit later.

DVDAuth also crashes for the same reason. Fixed it.

Apologies for late reply, I was very busy this week. This version fixed the problem and the disc is now dumpable. Thank you!

- added: /rr flag for DVD/BD retry to read
- added: check if the directory record length is really correct (The Shooting Love: XII Stag & Trizeal [DVD] (Japan))
- fixed: the buffer size when analyzing the IFO files
- fixed: Xbox/Xbox360 generates an incorrect hash

sarami, some Plextor DVD drives have different C2 offsets which are not sector aligned. I took a couple of C2 discs with negative and positive write offsets and a mix of audio / data and tested it on the drives I have here. I compared C2 dump with known good dump of the same disc and matched it with C2 error vector.
Starting from PX-712A, it takes drive 2 more samples (1 C2 byte is 8 bit) to calculate C2:

Code: Select all

PLEXTOR - CD-R PX-W4012A v1.07, C2 offset: 294
PLEXTOR - CD-R PX-W4824A v1.07, C2 offset: 294
PLEXTOR - CD-R PX-W5224A v1.04, C2 offset: 294
PLEXTOR - DVDR PX-708A v1.12, C2 offset: 294
PLEXTOR - DVDR PX-712A v1.09, C2 offset: 295
PLEXTOR - DVDR PX-716A v1.11, C2 offset: 295
PLEXTOR - DVDR PX-716A v1.58, C2 offset: 295
PLEXTOR - DVDR PX-716A v1.59, C2 offset: 295
PLEXTOR - DVDR PX-716A v1.5A, C2 offset: 295
PLEXTOR - DVDR PX-755A v1.08, C2 offset: 295
PLEXTOR - DVDR PX-760A v1.07, C2 offset: 295

(C2 offset is in bytes)

This is a problem because for PX-712A or later, any C2 error in the last 8 bytes of any sector will slip unnoticed into the final dump.

Should be an easy fix, instead of pre-reading 2 sectors like you do for Plextor, you can pre-read 3 sectors at a time and offset it based on a drive model.

I am trying to dump two DVDs, https://redump.info/disc/49280/ and the undumped Mac version of Enemy Territory: Quake Wars. However, when DIC version 20220301 tries to dump the LEGO The Lord of the Rings disc, it quits the dump after reading directory record 1/17, and when it tries to dump the Enemy Territory: Quake Wars disc, it quits the dump after reading directory record 2/191. What should I do here?
