I have a Windows 2008 R2 server with 2TB on a RAID 5 virtual disk. I added another 1TB drive to the server and added a 2nd Raid 0 virtual disk. Now when I go to Window disk management it is asking me to initialize. Should I initialize as MBR or GPT? Are there any problems with what I am thinking of doing. The data stored here will be archives that will not change very often and be backed up externally.
