Apparently the preferred defragger is Norton Utilities:

I'm pretty sure ABs preferrence is for SpeedDisk and if so, I'd have to

Mike,
Yes, I remember seeing discussion of the need for defragging
NT/Win2k servers (and AB's preference for Diskkeeper?).
http://www.diskeeper.com/diskeeper/diskeeper.asp
I'm guessing the Oracle DBAs are still curious about the
underlying I/O architectural issues involved.
regards,
ep
