i really don't know why does it happen this way but when doing offset corrected reading in EAC, it would often cut off more data than drive is capable to retrive. you could try to go to the last audio sector in IsoBuster and if it is still filled there, go one sectors beyond (or even further, until you compensate audio disposition). if this works out ok, you can save it with 'Extract From-To' command (will have to 'cancel' twice, it's ok). then you can extract or realign data in this file to cancel relative offset and it should be full last track then. only it's not safe, you would not get any warnings. when dumping with EAC, often only one drive would read last audio until the very end so i would do this to verify those last bytes on the other.

what did you mean here? Image
I was trying to say that the plextor drive could not read the entire track at the end and didn't throw any sync errors.. so if indeed there's data beyond the position specified in my post, the drive could not retrieve it.

Will try the sugestion from themabus today and see what I can find..

I tried themabus suggestion, these were the results:
* None of my drives saw more info that the info dumped by EAC with the LiteOn drive
* LG drive couldn't retrieve info beyond the leadout in ISOBuster
* In ISOBuster the Plextor drive was able to retrieve the info dumped by the LiteOn on EAC, that's good, but after the same position were the LiteOn showed data, in the Plextor there were just zeros.

I think I could say that at least in this version of the disc, that all the audio in the disc, the LiteOn drive retrieve all the info it can on EAC, the Plextor confirmed that info using themabus method on ISOBuster, none other of my drives retrieve more data after that.

Thanks

Done.. so pnkiller's last track has cut off data? Image I still think this is kind of odd.. pnkiller, have you tried checking the last sector in cdtool instead of isobuster?

Is it possible that his disc simply doesn't have any info on the leadout?

The serial isn't needed because there are no other versions from that region.

ah ok
BTW, why did you remove the Original flag from some of my discs?
