Thanks for your reply - let's hope my plextor will arrive soon. The good thing is that at least I can rule out the IDE-USB-Converter - I was able to redump a known IBM PC Disk with CDM and matched checksum.

No error there if to dump again, so it's not constant. So I've thought maybe DIC has missed an error occasionally.

20180108 test
Fixed: Also rewrite .c2 file if c2 errors exist.
=> if unfixed errors exist with EdcEcc.exe or edccchk or cdmage though .c2 file rewritten is all zero byte, maybe the drive misses to report the c2 error.

I've recently switched from DIC 20171010 to 20171210 and am now experiencing some problems.
Disc drive is PLEXTOR DVDR PX-760A 1.07 08/18/07 15:10

Sample 1:

Same problem here (Sample 1), where previous releases are working fine with the same drive.

Uploaded test version.

It can't get the directory record. It'll take some time to investigate.

rosewood: Have you tried to dump it with other tools, like, dunno, CloneCD? Does it really have audio tracks? Weird for VideoCD.

Tried the test version (20180112)

Sample 1: Probably works again, as it copies the data, but there seems to be a bug when it tries to calculate the hashes for the dat file.

Code: Select all

Moving .scm to .img
Creating bin, cue and ccd (Track) 11/11
[F:OutputHash][L:328] GetLastError: 2, Das System kann die angegebene Datei nicht finden.

Sample 2 & 3: Errors as before.

For Sample 3 the toc seems to be corrupt. This is not a Video CD, it's a Green Book CD-i disc with 3 tracks (1 CDI and 2 Audio).
I don't have CloneCD available right now and tried CDRWIN (recognizes tracks 2 and 3 only and refuses to rip).
Isobuster doesn't seem have a problem with it at all and creates a full rip.

Code: Select all

REM SESSION 01        ; Not supported by other applications (*)
    TRACK 00 CDI/2352
      INDEX 01 00:00:00
      REM MSF: 00:00:00 = LBA: 0
    TRACK 02 AUDIO
      INDEX 01 55:34:19
      REM MSF: 55:34:19 = LBA: 250069
    TRACK 03 AUDIO
      INDEX 01 57:50:69
      REM MSF: 57:50:69 = LBA: 260319

20180112.7z

I have some more multi-track CD-i discs, and they all have some problems. So far this is the only one with a missing Track 1. The other ones show a corrupt Track 1 in IsoBuster, but it can be extracted without Problems.

Sorry, reuploaded.

_disc.txt

Code: Select all

========== FULL TOC ==========
    FirstCompleteSession: 1
     LastCompleteSession: 1
    Session 1, FirstTrack  2, Format: CD-I
    Session 1,  LastTrack  3
    Session 1,      Leadout, MSF 63:01:29 (LBA[283604, 0x453d4])
    Session 1,     Track  2, MSF 55:36:19 (LBA[250219, 0x3d16b])
    Session 1,     Track  3, MSF 57:52:69 (LBA[260469, 0x3f975])

It seems "Track 1" is omitted. (same as isobuster)
And my cd-i disc (single track)

Code: Select all

========== FULL TOC ==========
    FirstCompleteSession: 1
     LastCompleteSession: 1
    Session 1, FirstTrack  2, Format: CD-I
    Session 1,  LastTrack  2
    Session 1,      Leadout, MSF 56:05:00 (LBA[252375, 0x3d9d7])
    Session 1,     Track  1, MSF 00:02:00 (LBA[000150, 0x00096])

There is "Track 1", but "FirstTrack" and "LastTrack" is weird.

The multi-track of cd-i has data sector in pregap of track 1 (to hide the data?), and manipulates the toc (by the same reason? CD was developed by Philips, so this is permitted?)
It seems the single-track of cd-i can't hide the data in pregap. (If it is done, it's only leadout disc on toc.)

If it's possible, please use subdump /viewtopic.php?t=10255
I need the sub file. Perhaps I think the track 2 of "Sample 3" is actually track 1, track 3 of that is actually track 2 and there isn't track 3.

Posted: **Sat Jan 13, 2018 5:44 pm**

Subdump couldn't get it right, so I tried it with different versions of CloneCD. Doesn't look too good either.

Here are some logs and the CloneCD sub file
