(c:) (MIssing)

Can anyone tell me what (C:) (MIssing) in the image is? And where did it come from?

I suspect it is the result of a Clone operation of the C drive.

Here is the image of Disk Management

Can you tell me what it is or where it came from?

Befort I turn off protection for this drive I will image the drive this weekend.

I'm concerned I'll lose something once I turn protection off.

Thanks for your reply.

According to the images the first shows the (C:) (MIssing) as a Folder, not a drive or partition on a drive. And the second doesn't show any correlation.

For those who stumble upon this thread.
I had the same issue.
The answer to the question: Where did it come from?

It was recorded on Lenovo Machines (which I have), and this is what Lenovo said inpart:

The following configurations may be affected by this symptom:
ThinkCentreThinkPadThinkStation
Affected SystemsAll
Operating SystemsMicrosoft Windows 7, 8, 8.1, 10


It can be remedied by following the steps in #2 above.
To add: I the TURNED original C: drive (system) from OFF to ON.

An individual tested SSDs and HDDs with this issue.
The images and results can be found on this URL, from microsoft's answer site:

Last time I updated my computer, it did the same thing; but I can assure you, your computer is fine, just turn off system protection for that C: (Missing) drive, and that erroneous entry will vanish; then just turn on system protection for your actual C:\ drive, and everything will be fine.
