I’ve got a big problem with my LiteOn 811S.
When I try burning a disc, the LED keeps flashing between RED and OFF (so there’s no orange LED to be seen). The strange thing is that the problem never happens when I’ve just rebooted my PC. Sometimes I can burn 4 discs before it happens, sometimes 6, …
When burning a DVD with the flashing LED, it takes about 4 to 6 hours to complete a disc, while I selected 4X, and the media are 4X-certified.
When I check my burning-results with kprobe, the discs burned in the bad way are very porely burned.
I have posted this error on several discussion boards, and they always give me the following solutions:
- bad media : not an option, since sometimes, the error occurs on a DVD+RW that usually works, and the Philips +R-media I use aren’t bad either I think.
- Bad IDE-cable: I used to have a rounded 40-pin-cable, and I’ve switched it with a regular 80-pin-cable.
I’ll give some further information about my system:
P4 2.8GHz (533FSB)
mobo: MSI 845PE Max2
OS: windows 2000 SP4
HD: 2 Maxtor 120GB SATA-drives (8Mb buffer)
these 2 hard disks are placed in 2 separate RAID-arrays.
The LiteOn-drive is the primary master, and IDE-drivers (intel INF) have been installed.
The thing that I find strange is, that when I look at the buffer in Nero, it stas constantly at 20% when burning slowly, and it’s at 100% when burning normally.

Any help will be greatly appreciated
edit DMA is on, btw.
