Please insert a disk into Removable Disk (N:).

I get File Explorer popping up with this message every few seconds.

I have nothing except my wireless mouse receiver in any of my USB slots.   I have moved the mouse receiver to a different USB slot but it still complains about N.

I am using Windows 10.

I have tried rebooting.

Any ideas please?  This is getting rather annoying now.

Cheers

Do you have a built-in card reader?
Does Explorer show N: under My Computer?

If you're absolutely sure N: shouldn't be there....

Right-click the start button.  Select 'Disk Management'.

When the window opens, check for N: in the list of drives/devices.  if present, right-click and select 'delete volume'.

I suspect nothing will show in there though as it's asking for a disk that is NOT present.  In that case, check in Device Manager for disks.  You may have one listed with a faulty driver.

After that, I would start considering SSD memory card slots if this is a laptop.  Is it?

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.

Also, run MSConfig and for testing purposes, untick 'load startup items'.  Restart.  If the issue is cleared, then systematically go through the Start Up Group items on the Startup' tab, re-enabling one at a time until you find the culprit.  Unless one sticks out like a sore thumb, in which case go for that 1st.

Drive N: in Windows 7 was for the Microsoft Virtual program.  Look in add/remove programs and uninstall if you are not using

Thanks all.

It does show up in File Explorer, does this screenshot help at all?
Disk N properties - hardware
General properties: 0 space used; 0 space free.

N does show in Disk Management, as 2nd screenshot shows.Disk Mgmt
I do have two other USB slots in use - the wired printer and wired keyboard.

Have you used a card reader recently? - the one built into your Pixma printer?  Windows thinks it's still in use.

To fix (unless there's a hardware fault) ideally you'll need to insert a card in the reader designated N: (or now "P:"!)
then change the designated drive letter - try Z:

Have you recently used one of your card readers

Good point.  I have never used the one in the printer (didn't know there was one!) and the Sandisk drive is an internal HDD.  But, I have used a USB card reader quite a lot and probably didn't eject it the proper way at some stage.

Ahh - you caught me out editing my last post when I worked out the SanDisk was an SSD :)
See if the error still appears if you restart with the printer unplugged
If it does then yes Windows has a temp file path to/on the removable card on the now missing card reader - I should have been more circumspect in my first post "do you now or have you ever owned a removable card reader ..." :)

Plug the card reader back in put a card in N/P and that should help you clear it.

Have restarted with the printer unplugged.  OK so far........
