Check the dma status of your drive. Here is a guide for doing that: http://club.cdfreaks.com/f61/troubleshooting-enabling-checking-dma-windows-vista-xp-2000-me-9x-101616/
The important thing to look for is Current Transfer Mode. It should be Ultra DMA 2 or 4.
Edit: I think there is also an option in DVDFab itself to enable DMA, but since I don’t use the program I’ll let someone else confirm that and tell you how to use it.
Yes there is an option in DVDFab to reset DMA
In Settings /General
Towards the bottom
Reset DMA button
