To extend C drive, you need to move partition D to the right, then Unallocated space will be right adjacent to drive C, so Extend Volume is enabled. Because Windows Disk Management can’t move partition volume, you need to run 3rd party software. Extend Volume can only extend the drive with right adjacent Unallocated space.įor example: after shrinking drive D, Unallocated space is non-adjacent to drive C and is on the left side of E, so Extend Volume greyed out for both C and E drives.Shrink Volume can only decrease a partition and generate Unallocated space on the right side.In fact, the advanced Shrink and Extend Volume are semi-finished, because NOT all partitions can be shrank and extended.
However, there is still no “ Merge Volume” and “Move Volume”. From Windows 7 and Server 2008, Microsoft enhanced its ability by adding advanced Shrink and Extend Volume functionalities. To manage storage device, Microsoft provides native Disk Management utility, which can create, delete, format partition, change drive letter and mark partition Active.
