some CDs are very messed up in this regard
with all gaps weird and stuff
usually older ones
equipment must have had some threshold for error tolerance when mastering i guess
larger at first, since consumer hardware wasn't that accurate those days too
e.g. PSX would position to requested second not frame
so 1:74 or 1:75 marker in subcode would mean little to it

I have 2 sec for the first track and 1.73 for the 11th. As I already stated if I go back 2 sec, I get only zero's but if I go 3 sec back I have data, resulting in 0 Write Offset. Let's assume EAC is wrong and I have 3 sec for the first track. The issue now is with the 11th track. I've also attached the sub screenshot and it seems to have only 73 sectors (224616 - 224468 = 148). Is this possible ?

so that would mean 0 offset and 3.0 s gap after all i guess

I get only zero's if I move back 2 sec (150).
http://lh4.ggpht.com/_WwCu7fWVlXw/S7yIVD-ziRI/AAAAAAAADLY/VCFeqvhALg4/s800/Untitled.jpg

I get some data if I move back 2.74 sec (224)
http://lh6.ggpht.com/_WwCu7fWVlXw/S7yIVLxxPHI/AAAAAAAADLc/wyG0t65ewvY/s800/Untitled1.jpg

On my other drive with +102, I have again zero's when moving back 2 sec and an error when moving back immediately more than 2 sec.

(look for '00 ff ff ff ff ff ff ff ff ff ff 00' sync pattern)
it would almost certainly be 2.74 then
to be completely sure about this offset you could check this CD with d8 capable drive
or do CD swapping thing

The problem now is that I have only zero's if I go back 2.0 seconds. I need to get back at least 2.74 to find some data. This is with a +667 drive. If 2.0 sec is the real gap I suppose I need a drive with even larger read offset... Is this correct ?

Using a 2.74 sec gap I get -588 write offset.
If I use 3 sec gap I get 0 write offset.

briefly checking 1st file it looks like data->audio gap = 2s; audio->audio gaps = 1.74s
which is not uncommon pattern
btw for some reason RAR complains about unexpected end of archive for those attachments

Thank you.

basically you would have to read ECMA-130 (chapters: 20, 21, 22) and examine .sub with Subcode Analyzer
here's a brief example with Mode 2 section (most often cause) affecting EAC's gap size detection

By the way, is there a guide available on this forum or anywhere on the internet on how to analyze the subs ? I want to learn so not to upload subs anytime I have this kind of issues.
Thx.

In the cue sheet generated by CloneCD I get 1.74 for all tracks.
I've also attached subs.
Thank you for your help.
