Win2KPro defrag

When I run analyze on my Win2K Pro notebook, it says 23% fragmented so I run defrag.

It takes it’s time and goes through the motions but when finished is now 17% defragmented. Most of the fragments are DVD movies I have encoded and they just sit there without being defragged, is there a way to have Win2K defrag completely?

Another question(2 for 1 what a deal!), if I use Norton System Works to ‘optimize’ the HD, Win2K analyze shows a ridiculously high fragmentation level. (up from 11% – 24%) but Norton System Works shows the drive as defragged and optimized perfectly.

What’s up with that?!?

Any info or links to info is greatly appreciated, this isn’t a dire issue but just a general question.

Thanks much,
OM
