Hi there, Ive been battling with this problem for quite a while.
Ive got an 8x IDE DVD writer which worked perfectly fine in the beginning. Took about 13min to write a 4.7GB DVD. However at some time or other it started giving me issues. When writing a DVD in Nero the buffer level (not read buffer) fluctuates heavily, jumping from 30% to 70% and all over the show whereas before it'd stay pretty steady at around about 100%.
The result is that now writing a DVD takes almost an hour instead of 13min.
The first time I got it working properly again was after I formatted my system partition and reinstalled windows xp. It worked fine for a while then but after a bit the problem reappeared.
The Second time it came right again was after I thought it had something to do with my motherboard. I sent in the board to my supplier and they sent it back saying it was perfectly alright. After I'd put the pc back together again and redone the bios etc. it worked fine again. Then after my friend changed some bios settings to add an extra drive temporarily it went back to the old problem (even after resetting the settings to what they were before...)
Another friend told me he had a similar problem with his writer and had fixed it by settings the IDE channel transfer mode to "DMA if available" in the device manager. But its been like that on my pc all along.
Anyways, i changed it to pio, rebooted, then back to dma and rebooted again. the problem remains. Ive also uninstalled my dvd drive in the device manager, rebooted and then tried again, problem remains.
Ive got ample hard drive space and the drive is defragged.
Ive tried increasing the ultra buffer in nero and it doesnt help either.
I downloaded the driver clean tool and registry checker from nero and that didnt help either.
Ive tried various bios settings, exchanged the IDE cable, taken the whole pc apart and put it back together, updated my bios, motherboard drivers etc. I'm at a bit of a dead end. Was going to format my system partition again tomorrow to see if that sets it right again. Has anyone got a clue what my problem could be? Any help would be more than appreciated..
