Finding "unidentified" Disk

Question

in windows 10 file explorer I see a disk that is identified by the letter "M:" and its name is the same as the system disk name.

When I try to see what is its contenet, I got the message "This folder is empty"

Using the property option of this device I got that it is 400GB disk and it has 148GB in use (see below)

When I used the "Disk Management" application (diskmgmt.msc), I couldn't find any device that point to the M: disk (the only disk that has the same parameters is disk C:

How I can remove this M: drive from my system
