10. ppendix 2. Testing the HDD controller board
To check normal board functionality, there is an additional method besides visual inspection and electric layout
analysis. It is based on the fact that a connection to the SATA adapter must be established when a functional board is
powered on. Established connection is indicated by the glowing PHY RDY indicator on the PC PATA – SATA
adapter. If the indicator is off, the board is malfunctioning. Please note also that a functional board disconnected from
its HDA enters the readiness state in a while after being powered-on and returns HDD ID (for the 7200.11 drive family
it also returns correct SN). Besides, to analyze the controller board condition, you can use the PCB swap method.
Boards with the same revision should be used for the swap procedure (Fig. 10.1)..
Even in that condition the donor board is suitable for initial estimation of the drive status (does it establish SATA
connection, does it spin up the spindle motor, whether terminal response is available). For further analysis including
service data inspection you should transfer to the donor board adaptive data from the malfunctioning PCB. To do that,
you have to resolder the ROM chip (see section 9, Appendix 1. Replacement of the controller board).
