Drive Rename Error, General System Tree Confusion

[boothruwindow]

I have a single-OS (Ubuntu Linux) desktop PC on which all of my hard disk was taken by the OS. Because I want to try different Linux flavors, I used the Ubuntu Live CD to reallocate all but 25 or so gigs to Fat32, so I could be sure that my useful stuff would be accessible from any Linux OS on pen drive, CD, or other OS installed in a similar, limited fashion. Trouble is that I didn't put a name on that Fat 32, and found out only after rebooting into my installed Ubuntu and called up Places > Computer that the assigned name is "465.3 GB Media". I decided that moving files between partition drives could be awkward with such a name, so I tried to rename this new partition to "My Stuff", and got this error"

The item could not be renamed.

Sorry, could not rename "465.3 GB Media" to "My Stuff": Operation not supported by backend

Well, I'm still a bit confused on the tree organization of these items under "Computer:///", where all drives are listed, and /home/media directory which lists active media sources, each with the folder icon. The error message didn't apply to my folder for that partition drive in /home/media, which had been renamed to "My Stuff", just as I had requested.

I have recently learned that Unix treats devices, including media drives, just like any folder, and since it keeps peripherals and hardware under the /dev folder, I can sort of process the fact that it has a media folder besides Computer:///, but I really can't follow why or what it does there. (at least in the case of Ubuntu)

It only got more confusing as I tried to move folders to my new drive - I got a system policy error, but was able to password past that, but as soon as I had mounted that new drive partition (drive named Computer:///465.3 GB Media, referred to after a rename as Computer:///465.3 GB Media/media/My Stuff), and expecting to see nothing there, I saw it had /media/disk, which means a new folder had been created in Computer:///465.3 GB Media/media ! Why does Linux need these folders to access drives anyway, and then why did it create a new one instead of use the one which I had in there already? Could it be that I had renamed it (I don't know what name it had before I did the rename directly under Computer:///)?

Thanks!

Edit: There was another error which I had forgot, and only makes it stranger - something about no such volume or drive, right after my login - so it appears to be a total failure, but until I did what the insane such as I do (the same thing while expecting different results) and then something different did happen - after double-clicking my Computer:///465 GB Media icon again, I then got the /media/disk thread in my File Browser.

Can you post the output of

sudo fdisk -l
mount
cat /etc/fstab

You can also look at the man pages ...

man fstab mount

and take a look here as well.
