Hi Wolfie
I opened Device Manager, checked Disk Drives, found SD/MMC/MSPRO Generic, must say took a chance by removing it, after which checked for the F drive, finding it was now removed from This PC.
However, in trying to play a DVD Film disk, refused to play it. A saved CD of holiday films opens and show picture without any trouble. Just my luck, rid one error and inherit another. My play software is VLC that appears to be functioning correctly.
Well on cold restarting computer, and rechecking Device Manager, the Generic drive has again been restored and the ref "F" drive is also showing in This PC window, back to square status quo .
