I tryed backup several PSone games
I have Toshiba DVD, reads subchannel and allmost everything i could tell, clone cd recommends toshiba DVD drives when reading.
i have tryeid 8x 10x 12x 20x 24x it still gives that error.
Alltough it may sometimes rarely work at slow speed.
What is most interesting, in other computer it works just fine, even with the full burning speed. Wich has same dvd and same burner, with same applications, os, and settings, only not same processor and motherboard. ODD!
