I'm going to try dumping that disc with all of the other methods I can find, and then see what sarami has to say.

I finished that data dump. It doesn't match a dump that I made with an older version of DIC

EDIT: setting the drive speed to 4x seems to have fixed it. Yay!

And the dump that I made matches a dump with an older version of DIC.

Thank you so much for everything! Tried reading a GD-ROM just now and the dump went just as it should.

However, now it segfaults after the dump. But all the data seem to be dumped correctly smile

But READ12 (0xa8) can't read it. Perhaps READ CD (0xbe) is also same. It's weird...
Is this a protection? I don't know. Maybe iR0b0t or Jackal or reentrant know it?

I re-checked again with CD Manipulator and Clone CD, it seems that even those tools don't know how to handle this sector properly. Clone CD fills sector 150 with "55" while CD Manipulator fills the same sector with "00". Does that make any sense? Which tool should I trust more?

Would it be helpful to upload a subdump dump?

By saying sector 150 you mean:
A: Sector with MSF 00:02:00
B: Sector with MSF 00:04:00

Some tools start sectors numbering from 0 and some from 150...
In any way plz upload SCM dump that HAS that faulty sector...

Is there any command combination that will restart an interrupted run? I got a Address boundary error partway through retrying sectors with c2 errors, and I'd like to tell it to continue testing the sectors noted in the c2Errors file. It looks like you can specify the sectors to retry yourself manually, but it'd be much nicer if it could resume without too much manual intervention.

Sorry, the sector 150 I'm referring to is at 00:02:00.

What's the best way to obtain an .scm dump without DIC? Dumping with DIC fails so early that it doesn't create a .scm file. I tried with "cd", "data" and "audio" option.

How to dump (almost same CDArchive)
e.g. http://redump.org/disc/30992/
1. dump the disc except the protected file using plextor drive.

DiscImageCreator.exe cd <driveletter> <filename> <drivespeed> /sf

* DIC detects the protection like this.

Detected [LASERLOK.IN], from 337 to 10336

2. when dumping finished, eject the disc from plex drive and insert it in optiarc drive.
3. dump the protected file

DiscImageCreator.exe data <driveletter> <filename> <drivespeed> 337 10338 /sf /sk 76

* CD has a offset, so please specify more +1 or +2 than endlba. (e.g. 10336 -> 10338)
* /sk is below.

        /sk     Skip sector for physical protect (e.g. proring, LaserLock etc.)
                        val     sector num

4. merge plextor image and optiarc image

DiscImageCreator.exe merge <plex img> <opti img>

* I don't test yet about other ring protection.

sarami: It's going in a good direction but to speed things up you could also code sector range extraction from those discs. It's way faster to read specific 'n' sectors than entire cd, and merge command that merges single sectors - just like CDArchive does.

D8 reads ok, but 'higher level' read commands fail. So my conclusion is that there's something either with Header or ECC/EDC.
It looks like these devices don't like such patterns?

Thanks a lot, with this test version I was able to dump this disk. Interestingly the checksums doesn't match with either CD Manipulator or Clone CD.

And even more interesting is that edcchk hasn't detected an error in sector 150 (00:02:00) and just detected it as Mode 1 data sector.

When you XOR with 0x60 you get 1 = Mode 1. It makes sense.
All other sectors are mode 2?

Because descrambled sector of LBA 0 (sector 150) is no problem. As you say, CD Manipulator and Clone CD is padding this sector by 0x00 or 0xff.

This is a similar case http://forum.redump.org/post/56314/#p56314

Firstly, you need to check by cdtoimg. http://www.mediafire.com/file/9b31r4fv4 … g.rar/file
This is a simple 0xd8 ripping tool. Please check if 1st sector is really same as dic's 1st sector.

Secondly, you need to check the pregap sector of 1st track.

DiscImageCreator.exe audio <DriveLetter> <Filename> <DriveSpeed> -5000 0

Please check the position of the sync (00 FF FF .. FF 00)

sarami, the dumps of cdtroimg and the scrambled DIC file differ. From what I can tell, DIC is missing the first 32 bytes of the image.

First few bytes of the DIC .scm image:
https://abload.de/img/dicscmrhd8k.png

First few bytes of the cdtoimg image:
https://abload.de/img/cdtoimgn8cv1.png

Trying to read the pregap threw lots of errors - log file and resulting dump available at https://www87.zippyshare.com/v/Xhoz9VMK/file.html

Is it possible that this is a disc with a mastering error instead of a copy protection?

Thanks for your help!

First 40 bytes are cut. Because .scm is an image the offset is calculated. I confirmed cdtoimg image was same as _disc log.

Thanks. I found offset of the pregap (and TOC) area was -22.

0020 : 00 FF FF FF FF FF FF FF  00 FF FF FF FF FF FF FF   ................
0030 : FF FF FF 00 01 82 00 61

Due to incomplete/garbage sync from 0020 to 0027, offset of LBA 0 is shifted to -20.

Thanks sarami for your great support!!

Is it now safe to submit the DIC dump? Which comment should I choose regarding this weird sector 150? What about the error count -  "1" as reported by CD Manipulator and CloneCD or "0" as reported by DIC+edcchk?

I've got a disc with three audio tracks followed by one data track. The dump completes without /ms, but the last track is misaligned. Running DiscImageCreator with /ms seems to work fine, but Read error. padding [2352byte] starts to appear around the area where the data track begins.
