“Windows Server 2008 “Extend Volume” greyed out”
“My computer system is Windows Server 2008 and recently there is always a low disk space to tell me my C drive space is low and must get some space. But in my computer, the files and folders are all very important and cannot be deleted. So I shrink D drive to release some free space. However, when I right click the C drive and plan to add the free space into it, the “Extend Volume” option is greyed out and cannot work. Why that happens and how can I add the unallocated space to the C drive? Any immediate help is greatly appreciated!”
Why “Extend Volume” greyed out in Server 2008?
As everyone knows, the Disk Management allows users to do many disk-related tasks, such as initializing disks, creating volumes, and formatting volumes with the FAT, FAT32, or NTFS file systems. Compared to the earlier version, Server 2008 Disk Management has some new features, especially extending and shrinking partitions, which can help extend a small partition.
But from the above situation, you can know sometimes the Extend Volume option might be greyed out. That is really annoying. Why did the “Extend Volume” greyed out in Server 2008? The reasons for that can be concluded as following:
The partition you want to extend is FAT32, only NTFS or RAW partition can be extended.
There is no unallocated space available on the disk.
The unallocated space (when available) on the same disk is not right after the partition you want to extend.
The unallocated free space is in the extended partition.
How to solve Server 2008 “Extend Volume” greyed out effectively?
Since the causes for Windows Server 2008 “Extend Volume” disabled various, here we offer different solutions.
Case 1. If there is no unallocated space available on the disk, you need to first shrink or delete another partition. But the unallocated space can ONLY be generated behind the drive you shrank in Disk Management. So you have to delete the partition located after the target drive you want to enlarge. As an example, if you want to C drive but no unallocated space on the disk, delete D drive first. After that, right click C drive again, you will find the “Extend Volume” is clickable now.
Case 2. If there is unallocated free space, but not right after the partition you want to extend, no solution can solve that since the key limitation in Disk Management is that it cannot move partition or unallocated space, otherwise, this problem can be solved easily.
Case 3. If the unallocated free space is in the extended partition, and then you need to delete all logical volumes inside the extended partition and the extended partition itself.
