I'm not sure why that would cause things to behave this way, but this certainly needs to be addressed before I troubleshoot any further.

Coco drives are addressed by the cable not be jumpers in the drive. If you have 
such jumpers, they probably should be set to 0.
There should be only one terminator resistor block in your system. If more than 
one drive has such, the last (highest number drive) should have the resistors.

PC drives may not be able to be used as drive0 without a twist in the cable. 
Such a drive probably will work as drive1 without changes to the cable.
