[FreeBSD] Silly Question

[LW Ellis]

Ok gang don't be to rough.
I am a long time windows user, 
and am used to running disk maintenance.
Scandisk, defrag, etc
Do I need to run something similar on FreeBSD?
or not?
I let my machine run 24/7 and have received the weekend reports
(which I found fascinating.)
If I need to run such apps, which one in the
ports do I chose?

Thanx all

Later, 
Leon
