Hello all. Iâ€™m hoping someone can help me shed some light on this.
I hope below is enough info for someone to help.
I had a BenQ 822 burner.
It worked for awhile then started making coasters 1 out of 5 DVDs failed during burn
Tried a bunch of things, DMA, slower burns, Different media etc. Same intermittent errors.
I then borrowed a friends BenQ 1610 burner. Was able to burn 15 DVDs ok.
I then shipped my old BENQ 822 back for repair.
BenQ shipped me a new a new 1620. Was very happy about that. (I thought)
I started using the 1620 and now I get 1good burn out of 5 bad burns.
Started reading a lot of things out there and not sure what causing my errors.
What I have verified so far
Remember fails are not consistent. Some burn and verify ok then it fails on others
DMA is turned on for all devices.
Running Nero 188.8.131.52
Install Adaptec aspi_471a2.exe
BenQ firmware is flashed to latest version B7U9
Check power supply voltage using Asus mother board tools sampled every 1 second. No major fluctuations in graph even at the time of a failed burn
Screen savers turned off
Power management turned off
Iâ€™m not running anything or using PC while burn is in process
Core applications are only running Virus, services, etc
Boot drive has 5GB free
Data drive has 20 GB free
I make sure DVD media is finger print free and dust free. Always covered back up
Everything is room temperature
Memory use is about 79 %
Media being backed up is DVD movie (backup) from DVDshink
Fails occur when DVDshink trries to plug in with Nero to do burn and also fails even when DVDshrink is closed and only using NERO
Not using NERO smart start or the Wizard
Ran defrag on all hard drives
Log files almost always look the same. â€œWrite errorâ€
Never buffer over runs or underruns
Last BenQ drive 822 had a few â€œSession fixation errorsâ€
PC seems pretty stable never a blue screen. Hangs once ever 6 months or so. PC runs 24 hours a day.
I reboot it every once and a while especially after some failed burns
Running as the administrator
Ran spybot to check and clean adware/spyware. PC apears to be clean.
PC appears to be virus free.
Not running any fancy services or devices in memory that Iâ€™m aware of.
Doesnâ€™t seem to matter if Booktype/bitsetting is turned on or off
Other DVD software installed
FYIâ€¦Sonic is also installed (came with BenQ drive)
InterVideo WinDVD 4
Ulead DVD player and MovieFactory 3 Disc Creator
Running Windows 2000 P4 1.8mhz, 256mb
IDE1 master 40GB HD bootdrive IDE
IDE1 slave toshiba DVD-ROM drive
IDE2 master 80GB HD datadrive IDE
IDE2 slave BenQ 1620
Using 80 wire IDE ribbon cables and drives are NOT jumpered using CSEL
Windows, Nero, Windows swap file running from IDE1
Nero coping data from IDE2 master drive to IDE2 slave DVD burner
I have not reloaded Nero or any other software yet because some burns work
Some burns fail right off the start and other 3 min to 5 mins into a burn
Some disks pass the burn but fail the verify
Tried different media and recorded at faster and slower speeds 2.4, 4, 8, 12. All of these fail at some point
BenQ +R 8x
Maxell â€“R 4x (made in Japan)
Verbatim â€“RW 2.4x
Generis â€“R Onitec 4x
Memorex â€“R 4x
Had one successful burn using BenQ 8x media burnt @ 12x and verified ok still (go figure)
Disk quality and focus check
Ran BenQs Qscan tool
Did some sample tests on different media. Qscan says it passes ok.
Maxell looked to have a very good Qscan and still failed.
Things I think I should try next
Sonic is also installed (came with BenQ drive) get rid of it
Run scan disk (just realized I should do this while writing this)
Open case and verify all cables and jumpers are set correctly again. Reseat all cables
Find a program to see what is running and what tasks are occuring burning the moment a failed burn occurs (any ideas on some software that will track what is running and when?)
Uninstall everything then reinstall
Look for Nero upgrade
Upgrade to XP
Try burner in different PC
Take really big hammer to BenQ drive
Go to Home Depot and get bigger hammer for PC
