[expert] To much not contiguous block

[falcaraz]

Every 20 times starting linux, the system check the harddrive partition,
; this is OK. I have the linux in two partition (hda5 and hda7) and the
swap partition to. 
When the system check the partition hda5 shows 0.2% non contiguous, but
hda7 shows 2.5% non contiguous blocks and this is every time increasing.
Is there any way to reduce this fragmentation?
I am runing Mandrake 7.2 with kde 2.01

Thanks for your help.
