Thanks for the info. I guess for this test I have to find a replacement
high-denisty drive. The drives in the unit are, apparently, high-density
drives but the disks are 360k disks made with another working system.

Rich, the 55F is a 96tpi drive while the 55BV is 48tpi. That
difference is likely the cause of your problem.
