Hi to everyone, it’s my first post here.
The reason why I’m writing it’s that I have a BenQ DW1640 since last October and I cannot get to burn a DVD with data verification OK.
I’m posting this message after reading a lot of post here and making a lot of test, waisting almost 50 DVDs in test.
First of all I’ve got to mention that for the tests I used some of the MAME roms zips (enough of them to fill a DVD5), because using them I can have to method of testing the burnt DVD, one method is with Nero data verification and the other is checking the integrity of the zips burnt in the DVD.
I started installing the DW 1640 in my computer with the following configuration:
- Processor: AMD Athlon XP
- Motherboard: Gibabyte GA-7NNXP
- Chipset: NVidia NForce 2
- Bios version: F20 (last one available)
- Memory: 2 Elixir DIMMs 512 Mb. PC-3200/400 Mhz. each one in dual channel
- Sound: On board provided by the NForce2
- Video: XFX with chip NVidia GeForce FX5200 and 256 Mb. in AGP 8x
- SATA controller: Silicon Image 3112 (on board)
- PATA controller: On board provided by the NForce2
- RAID PATA controller: IT GigaRAID IT821F (on board)
- Hard disks: 1 Segate SATA ST312002 6AS 120 Gb.
1 Segate PATA ST380021A 80 Gb. connected as Slave in 2nd channel of the PATA controller with 80 pin cable (DMA Mode: DMA Ultra mode 5)
- Optical drives: 1 LiteOn LTR-48125W connected as Master in 2nd. channel of the PATA controller with 80 pin cable (DMA Mode: DMA Ultra mode 2) Firmware: VS0D
1 BenQ DW1640 connected as Master in 1st. channel of the PATA controller with 80 pin cable (DMA Mode: DMA Ultra mode 2) Firmware: BSOB
- LAN: On board provided by the NForce 2
- Gigabit LAN: Intel 82540EM
- SO: Windows XP updated with SP2 and updated up to January 20th, 2006 (in Spanish)
- Burning software: Nero 188.8.131.52
Alcohol 120% 184.108.40.20622 (now uninstalled explained below)
- Drivers: Silicon Image 3112 controller v220.127.116.11
ITE GigaRAID IT8212F controller v18.104.22.168
Nvidia NForce2 v5.10 international
Nvidia Audio driver v4.57
Nvidia Forceware v71.84
Intel Gigabit LAN 82540EM v10.0
Note: After each DVD burnt with data verification failed I checked the integrity of the zips because I’ve read some comments that the Nero data verfication is not 100% reliable.
IMPORTANT: Before reading some post here about the incompatibility issue between the DW1640 with the IDE/PATA NForce drivers, I sent the burner to the RMA, they change the laser and they calibrated the burner, as errors in the data verification and integrity verification persisted I came back to the RMA and they changed for a new one, with this new burner the result is the same so as it’s too difficult that two burners where in bad state I started to investigate reading the posts here discovering the incompatibility with NForce drivers.
The media I used to test was always media supported by the BenQ DW1640. I used Imation DVD-Rs (Manufacture ID: FUJIFILM - Media Type: LM03) and Verbatim DVD-Rs (Manufacture ID: MCC 02 - Media Type: RG20).
With the NForce drivers I made unsuccesful tests changing the burner from 1st. channel to 2nd., changing from Master, to Slave and to Cable Select in each controller, I test by each combination of the burner connection taking the zips from the SATA hard disk and from the PATA hard disk in case that maybe there was a transfer conflict. I’ve also tried to burn the DVDs at less speed. Nothing works.
After reading about the incompatibility issue with NForce drivers I roll back to Microsoft IDE/PATA drivers (5.1.2600.2180), and I uninstalled Alcohol 120% because I’ve discovered that I was locking atapi.sys file and perhaps this could cause some kind of trouble. Doing this the burner improved a little in a strange way, this means: with the Microsoft IDE/PATA drivers with the Imation DVD-Rs at 8x the data verification failed in two sectors (instead of almost 7 sectors and it used to fail with the NForce drivers) and only two zips failed the integrity test (instead of almost 10 zips that used to fail with NForce drivers), this situation was found taking the zips from the SATA and from the PATA hard disk. I’ve tried after that to burn the Imagion DVD-R at 4x and for my surprise almost 20 sectors failed the data verification and almost 15 zips failed the integrity test.
After all of this I take the burner and I put it in an old computer that I have, with
- Processor: AMD Athlon 900 Mhz. FSB 200 Mhz.
- Motherboard: Epox 8KTA3+ with VIA KT133A
- Hardisk: Western Digital WDC WD200BB 20 Gb. PATA
In this computer no VIA Hyperion driver was installed, and the Windows XP installed was with SP2 integrated.
The difference that I noticed between the IDE/PATA Microsoft drivers from one computer and the other, it’s that in the old computer the driver for the controller is from VIA (it says something like Principal IDE controller bus VIA) and the other one seems to be a generic one (it says something like Standard PCI IDE dual channel controller - I’m translating from Spanish to English).
The Imagion DVD-Rs burnt with this old computer were all right at 8x and 4x!!!
So I’m stuck, I don’t know what else to do or where the problem can be.
If someone there knows something about this please help me!!
I’m run out of ideas.
Thanks a lot!!!
