The disk needs to be set up as a GPT disk in order to go over the 2 TB limit.
Here is an article that discusses it. Basically you need to right click on the Disk and upgrade it to GPT. Then you can add the additional partitions.
I dont have that option available - its greyed out - server 2008 r2

Unless your RAID controller allows you to add a unique SCSI ID / LUN number to the RAID partitions, then it just won't work. Repartitioning into GPT will be a waste of time because this won't change the fact that you have a single 5TB device.
Partitioning a 5TB into any number of partitions does not change the fact that it is still seen as a single 5TB disk drive to the BIOS. That is the deal killer. The BIOS has to see 1 target less than 2.09TB, for booting, and then the rest will be fine.

(I would personally get 2 small SSDs or disk drives, use windows-based mirroring, then make a 5TB lun for data)

The reason it is greyed out for you is because the OS is installed there.
When you create the Array, you should be able to set up Volumes that can be set up for the OS (100 gig) and Data (3-4 TB).

That is correct. You'll have to take it offline to correct the situation, and offline means offline for what could very well be a week-end because it will take quite some time to do a full backup

are there any tools or anything that i can do to reclaim or re-raid the drives while not destroying the current data?
