In addition to the advice you've already been given, I would certainly
pull out the floppy drive and clean the crease out with a q-tip and
alcohol and exercise the mechanism by inserting a disc and manually
ejecting it to see any trouble spots. That old grease has turned into
a thick substance that is hindering your drive operation. In about 15
minutes you can have it operating just like new again, it's an easy
job well worth the time that I've done many times on many drives. If
you choose not to clean it and do get it to boot now, the chances are
good it will become a problem later. The good news is these drives
aren't quite as delicate as some would believe and a simple, thorough
cleaning will have you up and running like new again. While you're in
there, wouldn't hurt to gently clean the drive head with another clean
q-tip with some windex on it. I know some authors would cringe at that
procedure but like I said, I've done many drives this way and have
scored at least 10 resurrections FROM the grave and 0 TO the grave so
the choice is yours ;)

PS: I don't recommend re-greasing the mechanism unless absolutely
necessary. Even after cleaning it with alcohol there is usually enough
residual grease between the friction spots that nothing else is
usually necessary, and new grease if not done properly can migrate to
areas which could cause a real problem.
