Windows Server 2008, Windows Server 2012, Extend Volume will not gray out if you have RAID 5 array in Server, each disk can set up at most 4 primary partitions, and adding unallocated space to RAID 5 primary partition is easier.Ĭlick on any partition to extend primary partition, if unallocated space available on any disk, if every disk has unallocated space, and the primary partition you extend is not next to it. Windows Server 2003, partition resizing on this system requires unallocated space continuous to primary partition so that you can Extend Volume on C Drive to extend. Add unallocated space to this partition need some steps depends on what system you’re using.
Primary Partition is always the partition with system boot data in it, because system can only be installed on primary partition. Can I add unallocated space to primary partition
