Another SafeDisc 2 theory

On our forum I found another posting on the SafeDisc 2 issue. This posting is a complicated technical story with thoughts of several people, and contains theories that might contains the real explanation. One of them is that it all depends on the Sanyo chipset:

The Phillips chipset is the chipset that is able to make working backups of SD2 protected disks that will work in any Writer or CDROM. This chipset is used in the following drives; Acer's, Artec's, Fujitsu's, Seimen's, HP 8250i, Iomega ZipCD's, Lifetec's, Medion's, Tevion's, Phillips, TraxData's, & Waitec's.

The Sanyo chipset is the chipset that seems to allow many burners to make copies that will work in the burner that made it, many times in other writers, and rarely in other CDROMS. This chipset is used almost all the other drives except those mentioned above(including Plextors, Creative Labs, HP's, Imations, Ricoh's, Yamaha's, etc).

Now one interesting fact is that Sanyo changed the version of their chipsets roughly midpoint of the Plextor 1210a run. The older chipset seemed to be able to make working backups of the SD2 discs a little more often than the newer chipset does. Thus the reason why many people with certain Plextor 1210a's seem to be able to make working copies of the SD2 discs more often.

But neither Sanyo chipset CAN NOT make working backups of SD2 discs that will reliably work on ANY other CDROM drive 100% of the time, where the drives using the Phillips chipsets can.

Yes, depending on the chipsets capabilities some of the problems with the SD2 discs may be able to be compensated for in the firmware. But it truly comes down to the chipsets physical capabilities when reading the various protection types. You can only do so much with software and are always limited by the hardwares capabilities.
