Interesting smile I always thought that /ns option should produce identical dumps...

None of the CUEs are correct. There's a malicious index injected (next index is smaller than previous index) in the middle of the track.

CUE: That format can't handle such things: https://web.archive.org/web/20160201021 … et/syntax/

CCD: CloneCD dumps always contain the .SUB file, .CCD file contains only the TOC, the index stuff is inside the .SUB: http://forum.redump.org/topic/12357/cdr … fications/
CDD should be able to handle such discs because Index data is inside subs.

MDS: The same as CCD.

Summary: Bins are correct and should be preserved. The problem is with CUEs. I'd ignore them for a moment and archive the subs or post relevant info in the comments...

Also Plextor is advised for such discs (I am not sure how normal drives behave when they read such weird discs)...

Sarami, could you implement simple inferface for stuff like this:

        ULONG start = 35000;
        ULONG end = 45000;

        while (nFirstLBA < nLastLBA) {
            BOOL bProcessRet = FALSE;

            if(nLBA >= start && nLBA <= end) {
                bProcessRet = TRUE;
            } else {
                bProcessRet = ProcessReadCD(pExecType, pExtArg, pDevice, pDisc, pDiscPerSector, lpCmd, nLBA);
            }

In some cases it's really needed to skip specific range because it errors out on one of my drives. Could you add some command line switch for this?

I'm having troubles with data command in latest git version. DIC seems to get stuck at the very beginning.

Is it possible to introduce another reading mode in which I supply disc offset and drive offset and DIC behaves as in cd mode (dumps multiple tracks) and pads missing data with 0s? I have drives with better error correction and I want to compare resulting dumps (track to track basis). Right now it's real PITA to do it due to offset correction. This feature would really be great. Something like data command but with offset correction and splitting tracks...

Hello,
   After some small research I managed to make use of DPM data stored inside MDS file. For this purpose a small helper tool was created: CDArchive (in the attachment)

Example game: http://redump.org/disc/38911/

Basically the result of the tool is this info:

DPM Resolution: 256 // It means that there's one sample of info for each 256 sectors block
DPM Entries: 8037 // 8037 * 256 = how many sectors are covered in this DPM analysis session (could be smaller by few sectors than image size)
DPM Start Sector: 0 // No comment

DPM Data: 0 0 0 2253 // Format: <IsInsideDPMBlock> <SectorStart> <SectorDensityDifference> <SectorReadingTimeUs>
DPM Data: 0 256 -1 2252 // The key thing here is SectorDensityDifference - it's used to detect start and end of DPM range
DPM Data: 0 512 -1 2251 // DPM start area has always positive difference and end area has always negative difference

DPM Ranges Count: 88

So as you see I managed to identify 88 areas with smaller density on the disc. I'd like to see this info in the DB someday. There's also a possibility to generate MDS file with this info (or rather patch existing MDS with this info).

Supported protections:
- SecuROM

To Check:
- Tages Twin Sectors
- StarForce

Tool usage: CDArchive -x i -d <SomeDirectory (not used)> -a <mdsFilePath> <minDensityDifference> <minDpmRangeLenSectors>

Example: CDArchive -x i -d D:\Test -a D:\Test\gta.mds 10 100

Tool must be run as admin because it has some other functions like ripping sectors which require admin.

Ok, thx for the info.

I also read somewhere that changing reading speed could help recover bad sectors. If the cd is spinning at low speed the head might loose position of the track when it tries to read scratched area. When the disc spins faster the head has less chance to loose position of the track because it "hovers above scratch for shorter time".

Maybe this could also be implemented. What do you think?

I tested the new version and there's one problem with ripping disc with uncorrectable C2 errors:

Need to reread sector: 260512 rereading times:   10/  10
bad all. need to reread more

After that DIC exits. Is it possible to continue execution even if there are C2 errors (I know the image will be bad but I'm aware of it)?

Is your C2 algorithm using C2 bits to select bytes which are good / bad and rereads until there are no C2 bits set (making use of C2 bits from previous rereads)?

This is a semi-complete list of weird images in IBM PC set. There are 4 categories:
REDUMP - Titles must be redumped.
TRUSTEDME - Titles with mastering errors coming from trusted dumpers
HARD - Weird mastering errors. All share a same pattern so it's very unlikely they are bad (weird track mode byte).
VALID - Images with weird stuff. Proper ones.

The obvious corrupted ones are the ones from REDUMP group.

Latest disc entry modification is also fine for me. The main idea is to grab cues from n last modified entries easily.

Hello,
   I have a small idea. When I download cues from main page, all the files inside archive have the same exact timestamp. Is it possible to change cue timestamps to match modification time of appropriate game? What do you think?

Hello,
   Does someone know why does my Plextor 760A seem to be locked to 8x when reading CDs? Did you come across such issue before?

This? http://forum.redump.org/post/54682/#p54682

I'm not the original dumper, I only saw the logs. In idlord's case /s 2 didn't help. In one of the logs you output a table describing TOC with pregap and this table is computed using RMSF in SubQ, yes? The problem with the CD is that RMSF in Q channel is bad but not random. For example at some point (say LBA 90000), RMSF is changed to some low value like 00:24:24 and goes up on each frame. After some sectors it restarts again and goes up.

RMSF goes 1 frame up with each sector (it's good) but the value is shifted and it screwes everything...
