I don't know if this belongs here, I thought I will try. 

Question. Is there a signal coming from the floppy drive which indicates  
whether the floppy has been changed, removed or present in the drive?
(I have looked at documentation from various manufacturers and the info.  
is not consistent. Some have a line called "ready" which goes active when  
a floppy is inserted in the drive and is read for access. Others have a  
line  called "diskchange" which goes active when someone opens the door).  
Isn't the interface standard across all manufacturers ? I am looking for a  
quick and easy way to detect a change in the floppy media, in the P.C.  
world, instead of sending commands to the floppy and looking their  
failure/success.

Thanx for the help
david
