No worries, your input has been valuable, so thank you.

For anyone else who might have an idea:

It seems to be hooked up correctly. When it is in the weird flashing
ready state, the boot loader says "Read error" or "Device error"
randomly. The heads oscillate back and forth very slightly as if it is
trying to align itself better on the first track, which doesn't exist
because it hasn't moved far enough into the pack.

I'm beginning to think the heads are bad which will be far too expensive
so I may end up giving up.

Thanks,
Aaron.
