DPM is a phisical protection and alcohol 52/120 perhaps records the LBA that reading takes more times in mds. Of course, the time when a drive reads a disc differs with each drive and each pc.
This is also why we're not hosting full subchannels: It's almost impossible to obtain 100% clean unaltered subs.
Yes, but only subQ channel uses CRC16. So about only subQ, it's possible to obtain clean subs.
I'm at a loss. Using the Optiarc with CDM and I'm getting different number of errors every time I run it again.
edit: Got the same number of errors on two different dumps, but different errors and mismatch on CRC.
So... I got tired of running it over and over and I decided to run it with DIC with c2 checking.

For the time being, you should not use your precious time until they(Jackal, reentrant) release the detailed dumping instruction of the ring protect. If this keeps up, we can't verify that their dumps is good or bad.

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)
I bought this. http://redump.org/disc/43270/
There are some error sectors in "SYSTEM.LSK", so this isn't "Ring PROTECH" but "Protected by ring" or "Ring Protect"
http://www.ta-ko.org/index2.htm
According to this site, Ring PROTECH appeared in 2001 summer. The ring protect before 2001 summer is different by manufacturer. e.g. Bleem! https://en.wikipedia.org/wiki/Bleem! Perhaps Blue Byte is also same.
So in case of this 1024B sector is DIC going to have support for this?
Yes, path/directory table can read correctly.
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...
Fixed a transfer length for reading Volume Descriptor of DVD. Concerning committing, plz wait...
Another weird bug. 2nd track misdetected as audio.
Combined Offset(Byte) -30576, (Samples) -7644
- Drive Offset(Byte) 120, (Samples) 30
----------------------------------------------
CD Offset(Byte) -30696, (Samples) -7674
Overread sector: -14Sector size "-14" is incorrect. "-13" is correct. This is fixed but I don't know whether the misdetecting is fixed or not.
Updated.

I suspect PX-716, but the LBA of "FULL TOC" and "TOC" is same if it is single session disc, so the LBA of "FULL TOC" is only used in multi session disc.
Gap detection glitch (last track).

Logical Block Size: 1024I had thought that "Logical Block Size" is fixed in 2048 byte. But Ecma-119 says below.
6.2.2 Logical Block
The Volume Space shall be organized into Logical Blocks. Each Logical Block shall consist of 2n+9 bytes,
where n equals 0 or a positive integer. The number of bytes in a Logical Block shall be referred to as the Logical
Block size which shall not be greater than the Logical Sector size.
That is, it is correct that "Logical Block Size" is 1024 byte and "Volume Space Size", "Location of Occurrence of Path Table" and "Location of Extent" is double size because "Logical Block Size" is half size.
http://redump.org/disc/43476/
File system doesn't corrupt, but CD-ROM that "Logical Block Size" isn't 2048 byte is perhaps rare or irregular. So, I think the OS that is newer than WinXP doesn't support it.
http://redump.org/disc/16920/ -- scrambled contents has the pre-last sector half-scrambled, half-descrambled and the last sector descrambled, so the descrambled dump should have the last sector scrambled and the pre-last sector inverted. It's a common Saturn mastering error. For some reason DIC leaves the last sector as is without scrambling it, that's not correct. And the earlier DIC versions work fine, I remember I've tested such discs, dumps were correct.

Only 3 sector? but clearly, 289 sectors are error if use 0xd8..
Track 3 is recognized as Audio mode in IsoBuster."
I guess the shift is caused by data > audio transition?
I don't know, but these sectors are clearly including the data sector. "00 ff ... ff 00" is sync, "69 b6 10" is the scrambled msf, "61" is the scrambled mode.

:The garbage byte (a part of the sync?) exists in first 8 byte of this sector. So, the offset is shifted by 8 byte... dic can't descramble these sector for this reason. Can you read these sector by the other tools (Isobuster, perfectrip clonecd etc.)?
Does this mean that if properly descrambled, the dump is correct and doesn't need any 0x55 fixes?
I don't know whether these sector are a mastering error, or a protect or not.
Is it really ISO9660 disc? If so, it is easily unbelievable that "Only" old Windows (3.1?, 95?, 98?, 2000? etc) can read it.

Attention
1. Before you report a bug, could you test the latest test version. Nevertheless a bug exists, could you upload all created file except bin, img and scm. And could you tell me the disc title ,region, barcode and ringcode.
Thanks several report, but I don't have these disc, so I can't test and fix them.
About PVD:
If it can't be read by IsoBuster, it is weird disc, otherwise dic's bug.
Yes. I'll add the total errors like edccchk in next version.
http://forum.redump.org/topic/16073/r09 … ification/
This disc will also show the errors are 3 in total.
Confirmed.
The pre-last sector is erroneous. The last sector is reverted/scrambled.
Exactly, the last 4510 byte is reverted/scrambled. BTW, does reading error occur if isobuster reads these 2 sectors?
It could this: http://redump.org/disc/42279/
Also Ring PROTECH cannot be dumped with Plextors.
1) Extract AUDIO using DIC.
2) Extract DATA using OptiARC.This is the only solution...
Does this disc has "PROTECT.PRO" file? or found the string "Allocator" in bin file?
https://www.gamecopyworld.eu/games/pc_s … _old.shtml
Unreadable Errors
The topside of CD #1 has been "damaged", a ring (about 1 mm) is clearly visible at about 1/3 of the outside of the CD.
GameCopyWorld isn't using the word "Ring PROTECH". If this disc is really Ring PROTECH, GameCopyWorld will also use this word.
Protected disc list: http://www.cdmediaworld.com/hardware/cd … tech.shtml
This protect is also adopted in Japanese disc. http://www12.plala.or.jp/t2-bun/list5.html
It seems edccchk doesn't regard the zero sync data sector as error.
And please use the latest EccEdc.exe
http://redump.org/disc/43270/
Same disc?
Please upload the scrambled and descrambled pre-last sector, and the scrambled and descrambled last sector.
Please try the latest. Btw, does this occur in another tool?

Latest DIC version fail at dumping this disc.
Old DIC version is fine though. here you will find full logs of both dumps (old and current DIC version).
http://forum.redump.org/post/54685/#p54685
Also I found one bug in CD-Text dumping. In function: SetAndOutputTocCDText -> strlen(pTmpText + uiIdx) crashes. iuIdx has some big value. This only happens with PX760. Other drive reads it correctly. Maybe before parsing those data structures subchannels should be corrected (packed mode read?).
Weird. Please fix if you can.
I checked under debugger that pDirRec[*nDirPosNum].uiDirNameLen = 0. It's an error during mastering phase?
Please see LBA 19 with IsoBuster and paste it in this thread.
Is this solved?

What protection is this?
VobProtectCD
http://redump.org/disc/42648/
I bought this. This is surely VobProtectCD (wiggles.exe). But this disc is almost compressed by a specific archive (archive.bin). So this can't be also detected by ProtectionID, A-RAY scanner.
To detect:
1. decompress archive, but it's difficult.
2. read main channel and search the invalid sync ("00 FF 00 FF ...")
