I just bought 1653s drive (CS09 firmware) and I have problems burning Dysan 2.4X +R (CMC MAG R01) discs. Burned two of them and none worked, unreadable results. Here’s the info of one of the discs:
Disc Type DVD+R Book Type DVD-ROM Manufacturer CMC Magnetics Corporation Media ID CMC MAGR01 Protection System None Region 1,2,3,4,5,6,7,8 Capacity 4,38 GB Free Size 0,00 GB Free Blocks 0 Number of Layers 1 Linear Density 0.267 um/bit Track Density 0.74 um/track Maximum Read Speed 7,7x Maximum Write Speed 2,4x Current Write Speed 2,4x CLV Write Speed Performance Descriptor 1 2,0x CLV
here’s the kprobe2 scan
Discs are fine, my old Sony DRU500AX burned them OK. Is this still a firmware bug and can omnipatcher be used with this drive. I opened the firmware with it and loaded tweak list (latest form the site, 2-13) and it changed write strategy of these CMC MAG R01s.
