latest f firmware 18x 18a1p (also tried c firmware)
cant read some (very light scratch disks) dvds
but reads in 111d a110 + 109 +sony 810 + 820
it this liteon very picky about such things. (disk seams 98% perfect)
also i have a bad disk (scratched fail a read copy test at 96%)
all the other drive read the disk + volumn label till it get to that section..
but the lite on just flashes its led (after a few tries) when you first put the disk in , it cant read it at all (no disk in drive)? error....
