Ignore/suppress this error dialog on drives not found

I'd like a new setting to appear that could be user selected to ignore/suppress this error dialog on drives not found such as for removables like floppy disk drives, and USB AiO Printer Scanners with a card reader in them, etc:

Also include the ability to scan All Local Hard Disks, instead only having available as an all-in-one the "All Local Disks".
