Windows 2000 includes a light version of Executive Software’s Diskeeper defragmentation software. Unfortunately, it has a few serious limitations, most notably its inability to schedule defrag sessions or optimize data in the Master File Table. Is disk fragmentation really an issue for Windows 2000 users? Should I upgrade to the full version of Diskeeper on NT and W2K workstations and servers? Is Norton’s Speed Disk 5.0 any better? I’m especially interested in hearing of any independent benchmarks you’ve run to measure performance gains and of any hassles you might have encountered when defragging Windows 2000 servers.
