I really doubt that your drive is at fault...could be, but it's way down the list of "usual suspects"
Has this pc worked with this version prior to having problems?
If so, I suspect the problem is the current version 220.127.116.11. Many users, myself included, have reported glitches, freezing, etc.
It's easy enough to test your drive.
Does it work outside of Fab?
You can always stick a disc in and run Nero CD-DVD Speed (just click on the link if you don't have it). You can do a number of tests. Try "Create disc". Here you can simulate or actually burn a test disc and get more info than you probably want...but you'll get answers.
Let us know,
Hope this helps.
