Right guys,
Well, my understanding of current hard drives is good, but when it comes to SCSI drives, still learning quite allot.
I require some assistance, if you don't mind two minutes.
We have an old school Seagate 4.3GB SCSI drive. It's clicking, and then powering down - to which our initial assessment would say that it's a head issue. So, we took it down the lab yesterday to perform a head swap. But we're stumped by the way the hard drive chassis has been made.
Please observe these photos:

But if we attempted to move the head stack out, the bottom heads will hit a series of pins. These pins go from inside the chassis down to the bottom PCB. So we can't move the heads out.
Am I missing something here, or being unbelievably naive?
Regards
Chris
