The Windows 2000 disk defragmenter is terrible.

Not really. You can't rely on a general defragmentation tool to move
all of the used blocks as close to the start of the disk as possible.
There are some fairly good reasons why a filesystem may want to spread
the data out across as much of the disk as possible (think cylinder
groups), and a disk defragmenter would adversely affect the filesystem's
performance by relocating all used blocks to the beginning of the desk.
You really need a tool that can reorganise the filesystem for the
purpose of shrinking the disk such as PartitionMagic.
