Jamie, some early CoCo Disk Controllers won't work with a CoCo3 when it's
running at the 2MHz speed.  Level 2 on the CoCo3 runs at that speed.

How old is you disk controller?  FD-501s and FD-502 will probably be okay, but
earlier ones may not be able to respond properly to a CC3 that's running at
2MHz.

I had the same thing happen to me when I first started using Level 2.  I had a
disk controller that I got with my very first gray CoCo 1.  Radio Shack was no
help then either.  I discovered that Level 2 would boot with my J&M Disk
Controller, but I only had one of them, and I had two CoCo3s.  I had to
purchase a better controller.
