So, I got a disc with real dummy files. Two of the data files fill up about the entire CD. The audio tracks are legit and dumped correctly. EAC and PF one correspond. How would I go about with dumping the data track?I get inconsistent results with DDump. Can I use ISObuster instead? (replace sectors with zeroes?)

OK thanks for the help and btw you need to fix that error about properly adding minutes in cues.

ok so eac gave me right pregaps, cool. how i exctract track4 pregap? if its hard talk to me in irc. and the disc UK

okay, same pregap lengths here also.

when you can extract track4 pregap without errors in isobuster, then its fine and can be easily done.

so, its an US disc then?

looks like you are trying to dump an USA disc(?)

track02: 2.00
track03: 14:22.74
track04: 2.00

any other drives to try out subchannel reading?

Re: Dumping CDLock CD's

Tomb Raider 3 disc 1 subs, 0 offset pxd8.

eac gives me the folowing gaps.

track02: 2.00
track03: 14:22.74
track04: 2.00

And a detailed guide whould be nice

Will have to make a little guide for this. I think there is a workable system for doing it, I have to thank fireball and ir0b0t for checking the subs and helping me out with it.

I'll try to put together an addendum for the dumping guide, just for this protection. Problem is I don't know how to analyze subs properly yet. If there was a good tool for it released soon it would help.

A combination of ISOBuster, EAC, cdtoimg, descramble_CDDA, a calculator and a hex editor is needed to do it.

Depends on whats recorded in the subs, so it would be better to examine them.

When you know the exact pregap length you can go back in isobuster and when there are data sectors you have to extract them first and add to the track.

Also, it could happen that there is a mixed pregap of audio and data sectors.

Re: Dumping CDLock CD's

2009-12-30T14:07:15Z

Yes but what I mean is that you have to manualy add a bunch of 00s in the beginning of the data track?

Re: Dumping CDLock CD's

2009-12-30T10:03:18Z

yes ghosty, (pre) means before

Re: Dumping CDLock CD's

2009-12-30T08:36:40Z

A question about cdlock, where is the pregap of the data track (track 4) goes? to the begining of it?

Re: Dumping CDLock CD's

Okidoki, shouldn't be a problem then.

bin/cue doesn't support this, just like CD Extra.

CD Extra is multisession, that's why the BIN/CUE format can't be used with it. In this case we are dealing with only one session with multiple data tracks inside, and that's fully supported by the CUE format.

Tomb Raider III is listed as having Illegal TOC on some copy protection web sites (don't remember which ones as I saw this a long time ago). My guess is the reason why it was considered Illegal was because disc copying software at the time this copy protection was released was unable to handle ripping the second data track. These days disc copy software gets around this issue by raw ripping the disc even when it's only ripping a single track at a time.

[EDIT]
Also bin/cue does support this as I've run my own image of Tomb Raider III from the bin/cue dump I've made of it. It might not have with virtual drives back then but now it's no problem for them.
