DVD Drive F Not showing on computer

I have 2 DVD RW drives E: and F: When I click on computer/open everything on my computer as far as hard drives and dvd drives show up except dvd rw drive F:

I also go to computer and choose manage and F: does not show up in Disk Managemnt.

How can I correct this to get my F: DVD RW drive to show.

I might add that when I put a disc in F: the disc will open and work but still does not show on computer.

Thanks for quick reply. I guess I am stupid. I had deleted partition D: on my hard drive so my computer had changed the dvd drives to D: and E: instead of E: and F:

I have another problem though because now my copy program will not recognize the source drive which I want to be D: Guess I will just have to figure hat out.

Any idea?

Tom

Thanks for help. Problem solved.
