Have someone make a boot disk for you to test with. Be aware that floppy drives and diskettes are high failure items. You may get to fix or replace an item.
Windows only checks the items in a very superficial way. That's nice, but not a good test.
I have an E machine 600is, windows me. My floppy drive will receive a disc, light up and you can hear it running, but all I get is a window saying: "please insert disc"...it doesn't seem to recognize the disc.
I checked my system driver and it says it is working properly. Please advise...JJ
