Floppy A Drive not recognized

I have a problem with a floppy drive not being able to be seen. I also have another computer exactly like the one in trouble and the floppy drive works fine in that computer. Checked Device Manager and it tells me the drive is working correctly, also all the drivers loaded seem to be the same as the ones in the working machine. All I get from the machine in trouble is a message to insert a disc in drive A: Any suggestions on any further tests I can run? Thanks

 

I don't suppose the floppy drive has a constant green light on it does it? If so, it means that the cable is on the wrong way round (at the floppy end, just turn it over), so you'd need to open it and swap it round.

 

Thanks Davey but this is in a laptop and has no lights and the cable has an end that can only go into the connector one way. Thanks for the thought.

 

If possible, remove the drive and try it on an identical laptop and see if it works there. If it does, then the floppy controller or connection is bad. If it doesn't work on the other laptop, then the drive is bad....
NOTE: controllers and laptop drive connectors very rarely go bad; it's probably a bad floppy drive.
