Question How to undo Portion on drives

It's difficult to determine what your goal is..

I see 3 physical drives in Disk Management...; the middle drive (240 GB SSD maybe?) appears to be your C;drive...and two larger 1 TB drives of some type...(cant tell if spinners or SSDs...although right clicking on each one and selecting properties will tell you)

Are you wishing to clone the existing C:drive over to a larger SSD, or....what are you trying to do?
(I was confused in the description of 'making two drives') (In any event, currently the larger unallocated space is to the left of the used space, which I think precludes simply expansion into the unused portion.

I'd start over, preferably using Acronis True Image or Macrium Reflect...

(Or, just fresh install to the new large drive, then reconnect and reconnect and blank the small one only if/when all goes well...)
