1) Open Device Manager. You can do this by clicking the start menu and typing device manager or by starting up devmgmt.msc.
2) Under your computer's name, look for the category named Floppy disk drives.
3) Right-click on the Floppy disk drive, and select disable.
That's it! You're done. No more annoying waits if you accidentally click it. And no more waste of screen real estate. Enjoy!
