We have just added a RAID5 array to a Windows 2008 R2 (Dell Poweredge) server, consisting of 3 x 2 TB drives. (4 TBs effective.) The desire was to have this array as the system drive, so we cloned the old one over with Acronis. It seems to have worked fine, as the server boots up nicely. There is only one problem... The 4th partition will not cooperate...
100 MB NTFS | 65 GBs NTFS | 1983 GBs NTFS | 1677 GBs unallocated
In Disk Management, when I right-click on this 4th partition, it only gives me the option of "Properties", nothing else. In general, the entire virtual disk, reads as 3725.0 GB online. It is a Basic disk, and it is MBR-partitioned.
I have wondered if it should have been GPT-partioned, but I was concerned whether I would be able to successful clone it while going in that direction. Just haven't worked with it much. I have also heard a bit about converting it. However, I really don't want to risk this. Can anyone out there with experience with this speak to this situation? Any solutions to be able to partition and format this unallocated space?
