Anyone knows how to detect if a disc is mode1 or mode2?
I ask this because when i was dumping the pc game harvester the new version of isobuster detected the disc 1 as mode2 and nero, cdrwin and an outdated version of isobuster (that was installed in my other computer) detects the disc as mode1.
Maybe it's mode2 because the other 2 discs are mode2. I don't know if it's a mastering error but it's weird and i never seen anything like this...

It is the last header bytes pair, if 02 = Mode2, if 01 = Mode1

i have this issue too, RetroGamer
IsoBuster would always return Mode2 on my LiteOn
even reported this to author
but it always remained this way
it must have been about year back though
maybe there weren't other reports and he forgotten
so maybe you should let him know too, and it would get fixed eventually

Thks iRobot, after testing a few discs with the sector view function i finally got it... it's like you said
I think it's a bug in isobuster... i use cdrwin for over 10 years and i never had that kind of problem.
But it's odd because the 2 other discs are mode2.
