Hi all,

Recently acquired this drive: Seagate Barracuda 7200.9 (ST3500641AS - Apple Model) 500GB

Firmware: 3.BTD.

Drive spins up (fine).

Stuck on busy.

UDMA (Off/On) - Nothing. You can hear it spinning at this point but can't hear the heads moving apart from the initial spin up. (when it's coming off parking ramp).

So I'm a little confused. No evident PCB damage and I have yet to check out firmware, just felt like brainstorming first.

Let me know if anyone's experienced this one before.

Regards.

Chris

If heads are not moving from the parking ramp then you wont be able to test the SA modules.
You say the drive spins so PCB is ok.
Could be heads are stuck/wedged on the parking ramp?
Do you have a cleanroom to check it in?
Or it could be a faulty preamp? HSA swap.


Loki

Cheers for reply Loki.

Not checked it in clean room yet, will do first thing tomorrow.

Most likely check to see if they are stuck, hoping it's something relatively simple. Not because of the operation, but because parts for this drive are a bloody nightmare.

Regards

Chris

This drive does not use a ramp, heads park in inner area of platters.

OP has also metioned clicking in a PM

Update

It only clicks once, then buzzes for half a second then stays on. It doesn't spin down until power is ejected.

Terminal output after powering on?

A terminal output would help.
I think it's heads.
As Nick says, this drive does not use parking ramp. It parks in parking area on the platters.

Probably is some damage to the SA, but need to see terminal output first.

Just to clarify - the only clicking is when the head begins to start floating after spinup.

You can then hear two 'thuds' and then complete silence (still spinning though).

I will investigate in cleanroom today and also will work on the terminal output and paste.

Cheers for the thoughts.

Chris

Recommendation: terminal output first, cleanroom opening second!

Agree, we need to see terminal output to see what's happening.
