I have a BenQ DW1640 OEM about 3 weeks old from Newegg. It came with retail firmware BSHB. I also have a Plextor 716A also about 3 weeks old. The Plextor is the Master and the BenQ is the Slave on the IDE channel. Computer is an AMD 64 3200+ Winchester, MSI Neo2 Platinum (yes, I have the nVidia drivers installed but have NEVER given me any problems), 2X512 OCZ PC3200 EL Dual Channel Platinum Rev. 2 RAM, 4x120mm fans in a Lian Li PC-7B cool running case, PC Power & Cooling TurboCool 510 ATX-PFC Deluxe power supply, and a couple of PATA IDE harddrives that are defragged and have >2X free space available to cache for burning DVD's. So I am pretty sure I have enough juice to run the BenQ.
Both optical drives have been fantastic so far and have not given me a problem before except with some very wrong CD-R media that Meritline.com sent me.
My current issue is with the BenQ 1640. I have used the drive to burn Verbatim 16X MCC-004 and Taiyo Yuden 8X T02 DVD+R's with excellent results. I have been comparing the time to complete and the burn quality of both of my drives.
Now I seem to have a problem with the TY DVD+R discs in the BenQ. I just burned 2 T02's with the same data (3810MB of DVD Video In Nero 126.96.36.199). The first disc took 13m08s and was with FW BSHB. The Nero REad Transfer Rate errored out as "Logical Block Address Out Of Range". Notice the red vertical line that's supposed to demark the end of the data is NOT positioned at the end of the actual data burned (3810MB) but is at the maximum for a single layer DVD. Nero Disc Quality also errored out when it reached the end of the burned data as well but with the error "No Additional Sense Information". Note that the Quality Score is "99"! The PxScan is not extraordinary, except that more errors are recorded versus with Nero Disc Quality.
Nero setup is for "Enable generation of a short lead-out", No "overburning" and "Finalize DVD" is checked but greyed out. In fact, just before I burned this DVD in the BenQ, I burned a T02 in the Plextor and just kept the everything the same except I then chose the BenQ in the dropdown "Choose A Recorder" window in the upper righthand corner and put the next T02 disc from the spindle into the BenQ.
When I put the Plextor burned disc in the BenQ and do Nero CD DVD Speed tests, there are NO problems at all. Likewise, the BenQ burned discs are scanned in PxScan without issue.
Lastly, all the discs, reguardless of burner used, play fine in my Philips DVP642 and also in the two optical drives.
SO... why the errors when using Nero CD DVD Speed and the BenQ DW1640?
