Windows 10: Merging Local Disk C and D.

Dear Whoever is reading this,


I Bought a WD Blue 500GB hard drive. I have two local disks, C and D. Whenever I download something it instantly downloads to C, which is the one with less storage. IF by any chance anyone knows how to merge both of the disks that would be great! IF not, then how do I make the Local Disk D my main disk?


Sincerely, Matheus.

how to merge c drive and d drive

It depends on a couple things.

If you have two separate physical C and D drives, you can't merge them.

If the D drive is a partition (not a drive) and its to the right of C:\ in Disk Management, you can right click C:\ then click Extend.

Press Windows key + X

Click Disk Management

Take a screenshot then post in a reply here.

If the layout is similar to how I described it, try the following. Make sure important data is backed up if there is any.

Select the D:\ partition

Right click the ‘D:\’ in Disk Management, on the contextual menu, click the ‘Delete Volume’ option. Click ‘Yes’ when the warning dialog appears.

The Volume you deleted will now appear as ‘Free space’, you will also notice that the disk icon no longer appears in the list of volumes.

Right click the Free space partition, and click Delete, click Yes on the Disk Management warning that appears.

The volume will now appear as Unallocated. Our next step is to merge back that unallocated free space with the system partition (C:\). Right click the System volume and click the ‘Extend Volume’ option on the contextual menu, click ‘Yes’ when the warning appears.

A wizard will now begin that will guide through the steps to merge back the unallocated space with your system partition.

The wizard provides a simple procedure to merge back the unallocated space with the system drive. Once you have selected the space, click Next, at the end of the wizard, you will see the amount allocated.

 

Merging C and D drives seems impossible

Hello all,

I know there is a lot of material on this issue but having read and tried stuff ( with Disk Management AND third-party solutions) for several days, I would really appreciate a definitive answer.

I have two drives, C and D, on the same hard disk. In Disk Management, C is on Disk 0 and D on Disk 1. I want to merge them. Most answers including answers from Microsoft advocate deleting D, so that its space become unallocated, and then extending C (right-clicking
C and choosing EXTEND). Like so many other users reporting back, after deleting D, which does become marked as unallocated, the option to EXTEND C is greyed out.

Third-party tools claim they can do it easily, but merging partitions only works when partitions are on the same disk (same hard disk, of course, but also same disk label, so in my configuration, if they are all on Disk 0). The reason I know that is not
because they make it clear, but because it fails otherwise, and, looking carefully at some of their screenshots, they are merging C and D partitions that are all on Disk 0. This would explain the endless torment of users trying out those solutions, including
the Microsoft Disk Management one and tearing their hair out because it never seems to work for them.

So my question is: what is the simplest way, if indeed there is a way, of merging "drives" of "partitions" C and D, with C being on Disk 0 and D being on Disk1.

Thank you for your advice.

Best.

Chris
