VMware Extend C Drive in Windows 2008 R2 is easy when you have unallocated space followed C Drive, but most of us will not leave space as unallocated after a new disk is added to VMware, so how to extend C Drive without deleting partition to make space unallocated? Try Partition Expert Server Edition.
Partition Expert runs smooth when extending C Drive, how about diskpart command line and server manager disk management? Windows Server 2008 upgraded disk management with Extend Volume and Shrink Volume to better manage server disk space with limitations. You can always find out extend volume greyed out when you have all free space distributed and assigned drive letter. Why would Windows do so? Why doesn't it just add a handle in disk management, so we can resize partition at will when we want to?
Microsoft released Windows Storage Space program, so I don't think they will improve disk management in future, so let's turn to other system utility to extend C Drive when the following issues come up.
Extend Volume grayed/greyed out in Disk management is the common situation when you partitioned all the free space on your disk, Extend Volume is only active when continues unallocated space followed to NTFS partition, but disk management provides no methods of moving technology when you shrink partition and make space unallocated, so once Extend Volume option greyed out, you have to:
So next time when extend volume grey out again, use Partition Expert to extend C Drive, and make a snapshot, a backup, recover it when low disk space alert shows in your Server system.
Windows 2008 R2 cannot extend C Drive problem happens when you're using diskpart command line to extend C Drive without bootable CD, that's to say, you have to reboot server and run diskpart in pre-os if you want to successfully extend C Drive.
How to make this success when running Server, because we don't have bootable CD for VMware Server 2008 R2, we don't want to pay much to solve C Drive running out space problem, nor do we'll cost extra fee to New Windows Server 2012.
When Server 2008 cannot extend C Drive, you can try disk management we mentioned above by deleting partition to make space unallocated and make extend volume active. Or you can try Partition Expert to Extend C Drive without deleting other partitions with fast speed and fewer steps.
