Problem: PX-716A improperly recognizes CD-RW discs as DVD-RAM discs and is unable to write or erase them
PX-716A installed as Cable Select (Master) on secondary ATA bus
Firmware installed: 1.06
Computer: Apple Macintosh dual 1.25GHz G4 “Mirror Drive Door”
OS: Mac OS 10.3.8
I just purchased a Plextor PX-716A drive and have observed that the drive fails to work properly with three brands of CD-RW discs.
TDK 12X CD-RW discs and Memorex 4X CD-RW discs are identified as 1X DVD-RAM discs. Any attempt to write or erase these discs using the PX-716A drive fails and the drive becomes inoperable until performing a cold boot of the computer.
Ricoh 1X CD-RW discs are also recognized as DVD-RAM discs, but with a speed rating of “1X to 20X”. Attempting to write or erase the disc results in the failure noted above.
With any of the above three CD-RW discs made in the burner that came with the computer (brand: HL-DT-ST; model: GCA-4020B; type: DVD-RW), while still being recognized as a DVD-RAM disc by the PX-716A, they are readable and files can be copied off them.
DVD-R and DVD-RW burning appears to work properly, although as I have yet to take delivery of any high-speed media my tests have been limited to 2X DVD-R and 1X DVD-RW.
Any clues as to the genesis of this problem and what its solution might be?
