DVD drive can't recognise some disks (Toshiba Satellite A100-192)
I've Toshiba Satellite A100-192 (PSAA9)
the dvd rom is supermulti /DL
I've strange problem, the drive can deal only with (-R) disks but can't even recognise (+R) disks,
I tried many generic names,
also can't deal with some CD disks, either the drive can't see the disk or the drive hangs .
any advise please
