Last year I bought a DVD-RW unit I installed on my XP SP1. It was sold as Sony even there is no brand printed in front of it. System recognized it as a Sony and it worked fine. I have burned around 100 data DVDs. Last week I upgraded to Service Pack 2 and then DVD is recognized as a LITE-ON 812S. The issue is that the burning time has been cuadruplicated, red light blinks to orange constantly. All the computer slows down while recording during an hour.
I've read and perform lot of things that didn't help.
I installed a firmware from Liteon.
I installed last version of Nero.
I installed last updates of SP2
Microsoft is the driver supplier on both channels.
Intel 82801DB Ultra ATA Controller
At the end it seems DMA is installed on DVD. After uninstalling (reinstalling) secondary IDE channel there is no more 'advanced configuration' tab on device manager but Nero log file says that it is ON (last burn)
I am attaching this log file where you may see some errors during verification.
When reading the disk I cannot find errors (random open image files). Even more, I use cdTree to catalog its content and no errors were found.
After all I only was able to reduce from one hour to 45 minutes recording time instead of usual 15, 4X.
Thanks in advance for a clue.
PS 'Add attachment is not workin fine' I choosed a file, added a comment and pressed 'add attachment' -> there's no attach here
