Drives e and f have memory...

I haven’t the faintest idea what is going on with my computer. A few days ago I made a music disc of 17 tracks. The disc was in a cda format. I tried to play the disc and was unaware that Microsoft apparently does not play that format. Yesterday I put a disc in Drive e to listen to music while on the computer. What came up was the 17 cda tracks. Sort of blew my mind on what was happening. I then put the disc in Drive f and the same occurrence happened. Is there some kind of memory the Drives e and f have that I am unaware of? Has anyone encountered this phenomenon?

I realize that you all just solved a problem with my USB ports and sorry to have to ask for another assistance.
