Win7 Extend Volume grayed out

How to fix Extend Volume grayed out/disabled in Windows 7?

A hard drive is used to store all kinds of files, to organize the files you need a Operating System such as Windows 7. To locate and use the files easier, you’d better create several partitions for different kinds of files. However, the partitions in a small traditional hard drive or Solid State Drive (SSD) are very likely to run out of space, especially for system volume. Originally, you have to start over to recreate disk volumes, but in Windows 7, you can resize partition directly. The advanced functionality of Shrink Volume and Extend Volume that inherited from Windows Vista can help you. However, many people feedback they have problem using these functionality: Extend Volume is grayed out, so they cannot expand a partition.

Win7 Extend Volume grayed out

In this article I’ll explain why Extend Volume is greyed out in Windows 7 and show you what to do when Extend Volume is disabled after shrinking D. Use free partition manager to move the Unallocated space and then Extend Volume will be available.

Why Windows 7 Extend Volume is greyed out

In short, to expand a drive with Extend Volume, there must be adjacent Unallocated space that is on the right side, otherwise, Extend Volume is disabled. There are 3 typical scenarios of Extend Volume grayed out in Windows 7 and I’ll show you one by one.

Scenario 1 – no Unallocated space

To extend a volume, there should be Unallocated space, or you should shrink other volume to release free space, otherwise, how could you get extra disk space? Some people do not know about this, simply open Disk Management and try to right click directly, of course Extend Volume is disabled:

Scenario 2 – the most common

Many people shrank the adjacent volume D:

Got Unallocated space:

However, Extend Volume is still grayed out when right clicking C drive:

You have to delete the entire Extended partition:

Now, when you right click C drive, Extend Volume is available:

Extend C drive by deleting all other volumes? Of course it is a BAD idea. As I said above, you just need to move volume D rightwards and then the Unallocated space will be behind C drive.
