I used to be able to burn DVDs with good test results. Then I suddenly couldn’t get a usable burn for anything. I spent some serious time studying CD/DVD speed and tried to burn a test disk - it failed to complete. After reading many posts on the forums, I checked the Device Manager and noticed the drivers were still there for a PATA insert card that I had removed (I lost a 120 Gig PATA HD.), so removed it. I also noticed there were 3 sets of Primary and Secondary IDE channel items. I have Win XP 64, so maybe 1 of them is 32 bit and the other for 64 bit. I don’t know.
After rebooting, there were only 2 sets of Primary and Secondary IDE channel items. I checked the DMA settings and one was on PIO transfer, so changed it to DMA. Don’t know which drive it affected. After all this, Win XP 64 would NOT/could NOT see the drives. I have a NEC 3550A (1.06) and I think a LiteON, but can’t remember and don’t want to reboot at this point. (CMOS recognizes both drives)
The only real solution I found that seemed reasonable was the one to remove “Upper filter and Lower filter” in the registry. Trouble is, there were 24 entries with the same name and only about 2 had an “Upper filter” in it. No “Lower filter”. I deleted the 2 entrees as MS instructed and on reboot, lost all external control of the system - both mouse and keyboard - even in safe mode. My only option was to revert to “Previous good registry”. Since then, I have found little else help.
I see here and there to remove the IDE entries and let Windows rebuild them. But they always refer to only 1 entry each of primary and secondary. So I’m very hesitant to do this.
It seems there aren’t many Win XP 64 units left out there, so not many answers. If anyone can help me, I’d truly be grateful.
If push comes to shove, I suppose I could buy a new SATA burner, but these drives have served me well in the past.
