A device which does not exist was specified.

Im installing windows 10 from a bootable USB and in the page where you choose a partition i went to the command prompt. In there i wanted to clean a disk but then it sais. (DiskPart has encountered an error: An device which does not exist was specified.
See the System Event Log for more information.)

A device which does not exist was specified

HI,

Yester 15-4-2020 I download and install this version "2020-04 Cumulative update for Windows 10 version 1903 for x64-based system (KB4549951)".

Today 16-04-2020 I received a pop-up window (A device which does not exist was specified) while trying to open E: or D: but C: is working fine. After the restart, my pc both E: and D: are gone from my Devices and Drivers.

 

Error Code x0800701B1 A device which does not exist was specified.

As can be seen by the two windows at the lower right-hand corner of the screen, the "1 Interrupted Action" window states that a device which does not exist was specified; however, as can also be seen, the computer does recognize two external hard drives.
It's like a barking dog with a wagging tale.

When copying and pasting files, jpegs in this instance, I can clearly see the images. When I begin the transfer, the software counts the number of files (over 20,000 images) and estimates the download time at 50 minutes. Then it suddenly displays an error
code window.

Oh, and when I try to eject the device, I get a window that says it's still in use, etc.

Step by step, how does one fix a laptop with a multiple personality? Does my computer need the Geek Squad or psychoactive medication?
