Dear Sergey
I have one dos exe program that when i run it ,return one number between 1 to 5
for example 1 => floppy is in drive and is not locked
2 => floppy is in drive but is locked
3 => floppy is not in drive
...

But your guide is only about ready or not ready drive.
Can you guide me more?
Thanks for your reply
Reza
