Hi,
I've a ´Momentus 5400.6 here that is spinning up, then ticking fast a fews times and then quitting with

Rst 0x08M
RW cmd 002F req = 18 F0 9F E5 18 F0 9F E5 18 F0 9F E5 18 F0 9F E5 18 F0 9F E5 00
00 A0 E1
opts = 00000000

RW Err = 84150180

The error is the very same whether the PCB is mated to the HDA or not?!

looks like your drive is dead. was it dropped or subjected to a power outage?

i guess its the 0 lba, and most probably heads problem

I would do proper diag to be extra sure...

The solution: water. The net book it came from was soaked, and some of it made its way into the HDA through the head amp/vcm connector.
Probably only an electrical problem that could be solved by replacing the head stack, but as the customer is not willing to pay, we won't never know
