I decided to defragment one of the Windows boxes on my LAN, yesterday. Well, its has been 36+ hours and it is still clicking away.

The Unavailable Box:
Athlon 1.4ghz
512mb
120gb/100mbps Western Digital Drive (About 75-80% full. About 4 or 5 months since last defrag)
All programs & services shut down.

I'm beginning to think something is wrong.

Are modern drives to big to defrag?
