It sounds to me like you have a floppy drive, and that drive is starting to fail, but isn't completely failed. Which happens.
Your best bet is to just unplug the ****er. I doubt you use it much, and if it's giving you errors anyway, you probably can't use it as well as you'd like, so you may as well just unplug it. Which is about as easy as it sounds. Just take the side of your computer case off, look for the floppy drive (It's slightly larger than two packs of cigarettes, if that helps you find it) and then pull either or both of the cables out of the back of it.
Ta da! No more floppy errors. Or floppy at all. :P
