Is there any way that when I open "Drives & Devices" that (for example), my User Home folder (E.g. C:\Users\Pierre) can show up, or a specific folder can show up (E.g. D:\Music) ?
No. That isn't the intended purpose of "Drives & Devices". It is more like Windows "Device Manager" than "Windows Explorer". It shows all the storage and handheld devices it knows about, and a Network item.
You can right-click on items in there and select "Remove & Ignore Device", but then if you want to see them again later under that section of MC, I don't know how you would add them back in.
There is the "Drives & Devices > Explorer" function under there, and if you set the "Mode" at the top of the function to "Only files in library", then only storage locations that contain files that have been imported into the Library will be shown. You still need to drill down to the location you want to view.
But all the above is irrelevant. The "Drives & Devices" and "Explorer" functions are there for specific reasons, but not for browsing your media files. More for certain types of maintenance work. A core design aspect of MC is the use of Views, and while it comes with default Views, the real power of MC is the creation of custom Views.
So learn about Views. Read the Wiki. Search the forums. Create a custom View that only looks in the directory you want to show. Within Panes type Views, try using the "Location" option. Look at the default "Audio > Files" View for an example of what I mean.
