Unallocated Space to C Drive

Hi Travis,

It appears that a disk partition was created but was never assigned its allocation. Assuming there are no files stored in the unallocated partition, perform these steps to combine it with your C: drive:

• In Disk Management, right-click on (C which appears next to the
  Unallocated partition.
  
• Select Extend.

Let us know if you're able to combine the spaces after following the steps above.

Regards.

 

Cannot merge C drive (disk 0) with unallocated space (on disk 1)

Hi all,

I need some advice on whether it is possible - and if yes, how to merge my C drive on disk 0 with D drive on disk 1.

The problem is: my C drive is getting full soon, but previously after I deleted D drive and make it unallocated space (the bar of current D drive will change to black from blue), I still cannot expand C drive by adding the 100GB unallocated space into it.
If I right click on C drive, the "expand" item is in gray.

I've searched online for solutions but so far only have seen same questions around. Does any one know the solution and do a big favor to explain how to do it step by step? Thanks much in advance!

P.S, sorry that the interface is not in English. Below page shows the "Disk Management" function, and you can see that:

1) Disk 0 has 55.78G, including C drive (55.21GB), 100MB of something I don't know what it is, and 473MB of recovery zone

2) Disk 1 has 100GB D drive, and 831.51GB E drive
