Hopefully Vigi has a suggestion.

EDIT: How can you tell if it's been cut off at the end?

I compared the two in hex workshop. This is what is missing from the beginning of the EAC dump.

I wonder why EAC didn't dump that?

But there seems to be something definitely wrong with offsets, both tracks are cut off at the end. My guess is the offset isn't really that huge negative one we use now. Have you tried detecting the offset with good ol' IsoBuster method? Take track02 LBA, go back 150 sectors and see what's there.

No hurry, going to bed now smile

1) EAC track02 dumped with -924 WITHOUT added pregap
2) PerfectRip track02 dumped with +924 (dumped by itself, without dumping track01 in the same session)

Even if it returns 0.00 it's necessary to hit F4 before dumping. Even without manually adding pregap, EAC resulting file shouldn't begin directly with data.

266474 is the amount of sectors ISOBuster gives for the cd...

Daemon doesn't let me load the cue from perfectrip.

I had to fix the cue perfectrip made... It matches the cd.

ISOBuster and EAC + added gap matches the cd also.

EAC -> exact combined offset
PerfectRip -> inverted sign

But I messed up and I am going to see if that is the problem. I am redumping them now.  I never took out the - in Perfectrip so that it was a positive.

In EAC I have it set to positive, which is correct right? Or do you put it as -924?

Track02 still has issues, I see that PerfectRip file still has less than 2.00 pregap, and EAC file still misses data at the beginning.

Can you look at actual disc lenght in sectors with IsoBuster?

I just dumped track 2 with pr with out dumping track 1 with it and it gave the same md5 as EAC with offset -924.

Could all the sub-channel errors that perfectrip gets effect the gap and make it messed up?

Gigadeath...

When you said if the perfectrip track 01 matches the one with ISOBuster and I said yes. It does match but I resized the ISO buster image of a 2 second gap and I didn't touch the Perfectrip track 01....  It seems to me somewhere Perfectrip is screwing up the gap?


here is the -924 EAC and PR track 02..

Are you sure you've dumped them with the same offset?
