repartition 2003 server drive?

[Shadows]

My last server had a small C drive and I was constantly trying to free up
space, so I had this (what I thought) great idea of just having 1 large
partition. I have one C drive on a array controller (RAID 5) 273 Gigs.

I want to have a system drive and a data drive. So a C and D drive. Can I
repartition with a 3rd party repartitioning software to make a 48 Gig C drive
and the remainer for D? Remember this is a production server, domain
controller, Operation Master. How would you proceed?

It's definitely happened to me several times in the past, but now I'm
careful not to create a boot partition bigger than the maximum size
supported by the RAID controller. For example with the HP 5i controllers you
get a choice of 4Gb or 8Gb when you create the array.

This is mainly an issue with RAID and SCSI controllers I think, not IDE or
SATA, but I expect someone can clarify this?
