I also experienced that, and my guess is that this behaviour causes
problems with the copy program I tried.

It won't work and it isn't needed at all. The 1571 already has a method
to detect single sided disks without producing errors and there are
commands to format a single sided disk as well. 

But the program should also work on an SFD1001, since it is like a 8250
that reports a drive not ready error on drive 1 all the time.

Mistake or not, thanks for that program! I really asked for something
like that before but nobody could help.
