when the hard drive spins up can you hear it
does it spin down or just keeps going


this sounds you got a faulty pcb board
might be open circuit on the power ic

but not to sure

When you swapped the PCB, did you try the donor PCB with & without the ROM?

A continuous BSY signal is a symptom of a corrupted ROM (among other things).

hello grig85

I did this already but I have the same problem

thank u for ur help

[jono-ats]

Gee, I wonder if the motor is up to speed . . . .

[grig85]

BUSY means drive started the task and that task remains unfinished. bad micro code in SA, and your drive is trying to load with it. got PC3000?

Thank you grig
