the difference of missing samples is 88, not that amount of drive offset diff. or 0. so i guess how far they go into lead out is also somewhat drive dependant. maybe your drive can see +32 cd perfectly but can not large offset? or maybe it can see even large offset, but in that case why EAC would not report it as overread capable? strange. but what's really strange: ~2k cd miss less samples than 1k!? *edit* ah, i guess it's maybe  a postgap, could be it differs in size on that middle cd.

in EAC, under Drive Options menu click 'Detect read sample offset correction'. and also when you read last autdio track with somewhat large positive offset, EAC will give error at the very end if drive does not overread in lead-out area.

I've had the error you mentioned only on my drive that has a large read offset (-677 EAC) but on all other drives that don't overread it doesn't give me any error.

Yes, it I also wished to tell:)
Though I am not assured completely. At me never was a drive with overread.

By the way, all that who copies the Japanese disks for SS and MCD I urgently would recommend to check correctness of last audio  track as at offset equal 1000 + the probability of loss data in last sectors of last audiotrack is great.
For an example. From 20 disks for SS which I have copied, only at pair last audiotrack on a drive with offset +6 (EAC) was correctly copied.
I should use other drive with offest equal -1164 to extinguish huge positive offset the Japanese disks.
Forgive my English

Forgive me, but I still haven't understood if a drive with +6/-24 offset can dump correctly or not. I got the same CRCs as Themabus with a drive like that.

i can only add to that brief summary about my drives:

Asus CD-S500/A (+1858 ;-30=1828)
+read negative offset audio
+very fast audio extract
-doesn't overread in leadout
-is rom not rw and can't read subchannel
-screws up data tracks so good for audio only

Plextor CD-R PREMIUM (+30 ;-30=0)
+overread lead-out
+somewhat fast audio extract
+read subchannel
-can't see far in pregap

Lite-On DVDRW LH-18A1H HL07 (+6; -30=-24)
+read subchannel
-can't see far in pregap at all
-can't see in lead-out
~most slow read but most precise

Would a drive with bigger offset "dump better"? Sounds strange to me.

most sega games from db have huge offset but it's positive. large offset drive +pregap overread is for negative offset games. for positive on contrary it's better to have lead out overread (it's somewhat rare but most plextors do that). but maybe it's region specific like most negative offset psx games seems to come from Europe region. majority dumped sega discs are Japanese.

I still have to work on the Sega games, my previous experiments were PSX only.
Say, themabus, which drives can you advise for each type of disc? I will trade my PX-800A for 760A for the 100b subchannel reading but still the reading offset is not enough (I think, Accuraterip lists +30)
If I can find them cheap enough I could buy 2 more drives.
Advices needed before I spend my money!
