Cloning Win 10 to external HDD

I've recently used the free version of Macrium Reflect to try moving Win 10 from my internal 66.6GB SATA drive to an external 120GB drive. After replacing the 66.6 with the 120 (as a new internal HDD), Win 10 was correctly pasted onto the 120GB drive and Win runs okay on it, but Device Manager now identifies that 120GB drive as a 66.6.
How can I make Windows update the properties of the internal drive and acknowledge that the 66.6 drive has been replaced with a larger drive?

Properties of disk partitions
On Disk Management, the storage properties are listed as 7.88GB Active, Recovery partition; 66.65GB for a Healthy, Page File, Crash Dump, Primary Partition; in addition to a 37.26GB Unallocated.
How can I add space of the Unallocated Partition to the Primary (C:)?
Or would it somehow be better to somehow "unpartition" the drive, putting all 3 of those partitions together (7.88 + 66.65 + 37.26) and make an Active/Primary partition with a capacity of 111.79GB?

I had that happen to me

when I cloned a 750 GB to a 1 TB drive. You have to extend the partition which you should be able to do with the cloning software. I'ved cloned from HD to SSD and SSD to SSD and I didn't have to extend the partition. It must only be needed when the target is a HD.

This is why I paid for my disk clone software and device.

I paid for Apricom since it will resize along the way.

For you to resize now requires ONE THING. That you are ready for the resize to fail.

With that out of the way, boot up GPARTED (it's on the web) and here's a tutorial on resizing.

And NO, do not merge partitions. Your reply later noted 37.26GB Unallocated so you use that to expand the 66.6 GB partition.

Suggested Freeware
Would you suggest using a free utility known as MiniDisk Partition Wizard (v9.1 - Free Ed.) for adding the space of the unallocated partition to the primary partition (drive C:)?

Sorry no.

Not a software I've used. I tend to keep using what I found working over and over.

If you want to try a new title, go ahead then report your findings.

A second and different no.

I've yet to see any disk partition software "add" the unpartitioned space to a partition. We expand the partion in size to use the unpartitioned space. To some this sounds like the same thing but as I write software, to me it's not the same thing.

If MiniDisk PW can do the job, why not?

If you want a free partitioning tool, try this one.

I've been using the free Easeus Partition Master for several years, and it works just fine for me. You can download it from
Good luck.
