I run with two 8 inch floppies (QUME 842s) and a Compupro DISK-1
controller.  I have been having trouble booting my MP/M 8-16 system.
What happens is that the MPM loader needs to read a file from the
data area on the floppy, and when it does so I get a BDOS Bad Sector
error. 

The possible reasons are 

1. bad drive
2. bad disk
3. bad controller

It isn't the drive: I get the error when I interchange the drives so
that the old A is the new B and vice versa -- the new A gives the same
error.  

It isn't the disk: I tried it with several disks, and it happened with
each. 

That leaves the controller.  Anyone care to comment on whether or not
a controller would do flaky things to reads and writes from just one
or two tracks on a floppy?

thanks.
