On an SBS 2008 server, I have a RAID 5 array of 4 1TB disks so the usable space is 3 TB. The drive shows my 100GB Drive C partition, 2TB Drive D partition, and 756 Unallocated space. I want to use the 745 unallocated but Disk Management doesn't give me an option to create any volumes, they are all greyed out.
I realize MBR formatted volumes can only be 2 TB but why can't I have an additional volume here. We need the storage space and it's so frustrating seeing it there but unusable.
Is there any way to access it without doing a complete server rebuild? It's a Dell PowerEdge T310.
Thanks so much for any guidance
