Since your Amiga recognizes the KICKSTART disk (other symptoms as non-kick disk)
it should read the first track/ first side successfully. I would
look at the head select signal, the step signal or the step direction signal.
All these signals are driven by one of the CIA devices. Might be a defect there.
Try to exchange them, if the behaviour differs from now, then ... you've
got the defect.
