I am installing WIndows 2008 on a server with four 2TB drives setup in a RAID 5 config (Adaptec 2420). I load the drivers and the drives appear as 2 separate blocks of "unpartitioned space" - one is right at 2TD and the other is at 745 GB or so. I created a partition on the 2 TB space of 200 GB for the O/S to install (might be overdoing it a bit, but I want plenty of room). Is there a way (if I leave the rest of the space unpartitioned) to make that one single large drive after the O/S installs? I read about the GPT drive formats but it seems that it need "clean drives" to convert to GPT.
So how would you use a large drive like that to install the O/S or are you just out of luck?
