I have 4 1TB drives in a Raid 5 configuration but with server 2008 installed 745GB are unallocated and cant be used. OS is on these drives and needs an MBR partition so cant use GPT. I've also learned that MBR is limited too 2TB. During install Disk0 shows 2 seperate instances of unallocated space one with 2TB and another with 745GB. The server 2008 install wouldn't install on the 745GB on Disk0 so I took 745GB from the 2TB instance on Disk0 which installed fine. The problem is that I lose 745GB that is never reclaimed....any ideas? Thanks in advance!
