[thelist] Defrag software for mac osx

[Joshua Hmielowski]

any one familiar with good defrag software for osx?
I currently have used Norton system works 9.2 and that worked before.
However , if I have major problems on my hard drive,
it has to be booted from the disc. For what ever reason I can run it 
from the
disc but I get an err every time and it does not fix anything.

any thought appreciated.
