After installing your XP/2000 PC with all software and data. Run at Cmd line like FOR /L %f in (1,1,10000) do md %f
And then (not on root dir. C:\) FOR /L %f in (1,1,50000) do echo Hey > %f
This will create 10000 dir and 50000 files that you can delete. This increases the MFT size. Download Diskkeeper demo. Run MFT defrag once and you will probaby never need it again :).
