I have a BenQ 1620 DVD drive installed in a Plumax External Case equipped with a Prolific PL-3507 ChipSet. The system is a Sony LapTop with a 2.8GHz P4 processor. My HD speed is 30MB/s (tested via Nero) and my DVD Burst rate is 24MB/s (also tested by Nero). I am running the 47L9 DVD Firmware for a BenQ EW162I external drive. The 3507 Firmware is the latest 2004.12.09.200.
I am using a WinXP/SP2 selective startup with no virus or firewall programs running. The discs are Yuden T02 +R batch #1125.
It appears that MAX speed I can obtain is 15.36X (P-CAV). There has been talk about T02s with batch numbers 1125 and 1133 being BAD but I donâ€™t know if this is my problem. See Attached.
Anyone have any suggestions ???
