OK, well "all's well that ends well" I guess.
At least you now will have your os on your faster drive, well done
Now what was your original question?? pmsl
Run the WD tools on the fragged drive, see what they say, if they say the drive is OK, try a different IDE cable and run defrag again.
EDIT: Just running through your boards manual, it's not that different to my old P4C800E Deluxe which was a top board in its day.
