Partition Issue

I'm at a loss.

I kept running into an issue with space on my C: partition. Went to expand it by allocating space from the D: partition since there is tons of available space.

When I pulled it up on Disk Management and looked at it, something didn't look right.

Then I did some research and it hit me.

When my computer was built (it's a pre-built), Alienware made Disk 0 the Data portion and Disk 1 the Boot portion. I have linked what the Disk Management screen shows above.

Is there any way that this can be fixed?

I try to do my own work, but this is outside of my wheelhouse so I would appreciate some insight.

Thank you for your time.
 
Those are 2 different physical drives. 128GB (OS drive) and 2TB (Data)
Not simply 2 partitions on the same drive.

You can't just take some space from the other physical drive.


Solution?
Replace your teeny 128GB SSD with a 500GB or 1TB.

What make/model is your current drive?

Well, that's a relief.

I think what threw me off is the Data drive doesn't have a make/model listed, it just shows "ST2000DM001-1ER164"

Boot Drive is a SanDisk X600 M.2 2280 SATA 128GB.

I appreciate the rapid response on this.
