all was working great after I gave is a thorough service and clean out.. Just set it up for some practice and bumped the floppy disc I had sitting the disc drive, guess what drive no does not "see" a diskette as being in the drive,

Hi SilvaSurfa.
I had the same problem.I am sure the drive will be OK. The fault will a slipping belt on the floppy disk drive or a broken belt.
when the belt slips the floppy sends queer messages to the KN2000 screen, no disk in drive, for different keyboard, ETC.
Good luck!! the KN2000 is a great keyboard.
Kind regards.
