Incongruent Disk request

To save a k words I've attached 2 images.

The cancel option requires 6 clicks before it goes away, comes back one more time and goes away with a single click.  From there on everything returns to normal and I  move the files.

btw it just happened when I tried upload this images

You appear to have disk errors.

Back up your data first and now. Then run the vendor's disk test software to check for errors.

It appears you will have to replace the disk and reinstall Windows.

could this be why the Device Manager is is doing this
Instead of this.
Or why a drive assigned the letter  P shows a drive letter of N?

Does the fact the this is a SSD factor in?

The last couple times I uploaded attachments the problem didn't occur!  How weird is that?

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

If you have disk errors, software may react in a different way because software is damaged.
your device manager behaviour has nothing to do with above problem - it is normal
you are simply confounding disk manager and device manager

running a diag on your disk is the best option - as John said

what disk model is it?

Your Disk manager lists don't seem to tie up, can you post a full list please

I wondered before i saw the Disk label if you had some kind of mirroring going on, do you? and is the destination there?

Ok, the whole issue has been resolved.  

Re the drive letter issue.  I have learned that Changing the drive letter on one machine means the drive will have the letter when I plug it into that computer.  When I plug it into my other computer I should see the drive letter it had the last time it was plugged into that computer.

Regards the Drive the Laptop didn't see. There was a network drive on my system, that was not being accessed but which saw that drive as it's own, and wouldn't let the computer list it in "This Computer".  When I changed the name of the Network drive the network released it, as it were, it then appeared in the drive list of "This PC".

I now realize that changing drive letters in a local thing, and that that big drive did not appear with the other drives because if the Network drive letter conflict.
