Shortly before moving I ran across the worst fragmented by percentage system I’ve ever seen. To give some background the system was an IBM x336 running Windows 2000 Server (yes, 2000 Server) and it had been up and in production for 5+ years. As you can see the 10.6GB partition for the C-drive is reporting 124% fragmentation!
The screenshot from the above is taken by an old version of Defraggler (version 1.21) with the defrag taking about 12 hours.
Why is it that no-one ever does any maintenance on their systems?
