Every disc gives me the Scsi error ILLEGAL REQUEST:READ OF SCRAMBLED SECTOR WITHOUT AUTHENTICATION
They seem to rip fine but some games are missing an entire quarter. It doesn't throw any errors, it just doesn't seem to notice that there's any more content there.
I can't imagine it's scratches or damage. I can't see anything and literally every disc causes the error, although only one or two have footage missing (at least as far as I can tell).
