Though if the floppy driver is correctly written when you try and write 
in a standard double density format it should be able to tell the drive 
to use 250K, which is IIRC why my 1.2 sounds different when reading a 
360K floppy to when it's reading a 1.2M. Cirtainly it sounds to me like 
the speed is changing.

Yeah that would be the sure fire way, I have a couple of one perticular 
drive type, where one was supplied as a 1.2M drive and the other was 
supplied as a 720K, so that sounds like it would work.

Cheers.
