Just a stab in the dark, I got a PB140 the other day (in an AS-IS basis) and surprisingly it works.
But it won't boot from the hard drive.
So I took it apart and poked around (after watching a few videos online). From what I can tell
power is reaching the actuator arm and spindle (when I use a screwdriver to move the spindle in
the centre) it seems to jump a bit (when connected with power). If I'm not mistaken, then
that means that the PCB on the disk isn't sending commands to the disk?
So the disk isn't spinning at startup. I'm trying to figure out if it's the PCB or the motor.
If power is provided by way of the scsi connector (on the PCB), and power flows to the actuator arm
(I'm assuming given my observation), can I assume that the PCB is receiving power and functioning?
Is there any other indicator that a PCB is functioning? There is no indicator light on the PCB.
By the way it's a Quantum Daytona 341s.
