mac / backup

[yokota]

i would appreciate your help concerning backups on mac 7200/90 os8.5.
i have problems reading out the psx cd with astarte2.0, at first it works fine an then i get errors reading the psx cd to the harddrive. is this some kind of protection on the newer games (the last time i made a backup is looong ago). thanks in advance

if you are getting errors when reading a psx game its damage in some way clean the disc it maybe just dirt
