Thank you both for your time and trouble. According to Software Manager, Mtools is installed; but where it is I cannot figure. It is not anywhere in the Menu.
Following altair4's suggestion, the Terrminal returns the following:

*** end of that mess ***
Note the Error message about the GPT table being corrupt. That is the same message that GParted gave me.
This is not a big problem. The other day I simply wanted to change the name of the drive, and could not do so in my Linux system (Mint Main 14 Cinnamon). I then plugged the drive into my notebok with Windows 7 and easily did it. I then wondered what would I have done without Windows. Little things like that bug me

I look forward to the day when I do not have to rely on Windows to do something because Mint can't. That will be nice.

Thanks again.
