Hi. I just bought a Pioneer DVR-A09XL (black) along with a Kingwin USB2/Firewire external enclosure with Prolific 3507 chipset (rev. C). Upon connecting to my 3 computers - a Win2000 P3-700MHz desktop through USB2, a Win2000 P4M-1.7GHz laptop through USB2, a WinXP P41.5GHz through FireWire - I was not able to burn DVD-R at any speed. Reading was Ok and fast (12x), but writing produced nothing but coaster. Since I was using 8x Velocity DVD-R (http://www.amazon.com/exec/obidos/tg/detail/-/B0006JLAN6/102-7566514-0834526?v=glance), I tried my burning at 8x, 6x, and 4x using Roxio Easy Media Creator for data disk, DVDecyptor for ISO image, and Pioneer bundled Backup software. At 8x, burning died at leadin, at 4x it died at 5%, at 2x it died at 25% on WInXP with DVDecyptor. On WIn2000 laptop burning of 8x died at startup with Roxio reporting “SCSSI command aborted by host”. On Win2000 desktop, Pioneer Backup simply hang at 2x.
I have upgraded both A09XL and Prolific 3507 firmware to latest as of July 22nd. Although Pioneer site said the upgrade needs to be done through IDE bus, I was able to upgrade through USB2 to firmware 1.57, and again latest Prolific firmware. I’ve verified both upgrades were successful by the upgrade popup message, and checking firmware versions after the upgrade. But the burning failed before and after the upgrades.
I haven’t tried to connect the drive to IDE internally yet, since I really want to make it external so I can share it among my computers. I read many horror stories regarding connecting burners through USB2, but mine didn’t even work with Firewire. Since folks forum seem to have had success with burner connected to Prolific chipset (even at 16x burning through Firewire), I wonder if anyone can point me to the next thing I could try.
Thanks a bunch in advance.
