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: http://imgur.com/a/uQu46#2 We would normally move the heads off the platter, secure them, and then swap head stack. 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

These are little monsters. Very delicate and fragile internals.

There is a different approach to swap heads to these. It's do-able, but requires vast previous experience and care.

I suppose elaborating on that would be out of the question.

Outsource it.
