defragmentation on M$ disc?

[Joris Huizer <jorishuizer@planet.nl>]

Hello everybody,

I'm wondering, is 't possible to "defragmentate" a M$ disc while running 
in Debian? I want to make a partition there to try debian/testing (I'm 
running Woody right now but some things are a bit old :-p ) , and I read 
the M$ disc needs to be "defragmentated" in order to do repartitioning 
without having to worry about losing information (is this correct?)
Now the stupid windows defragmentation tool keeps restarting as other 
stupid programs are writing so it'd take ages to defragmentate a disc of 
40 GB :-P So I want to know wether this can be done under linux (I can 
mount the disc without a problem)

Thanks for any help,
