Maxtor 90320d2 missing component

[helpless]

I think this board has a missing component, can you help me identify it? Maybe a transistor or a chip. Thanks.

The voltage on each pin might help to identify it.

Is this one clear enough?

Thanks guys. The picture is not bad, but what the hell is it? It says PCLK on the board and I am unable to read the marking on it.
I thought that finding the component was easier than finding a board. Looks that I'm mistaken?

SPCLK, SPDATA, SPSNS appear to be part of the spindle motor control section. You need to do some circuit tracing in that area.

Hello ,
What Are You Trying To Do .Is It a Data-recovery Case Or a Question Out Of Engineering Curiosity

Trying to repair the drive. It spins up, starts clicking, stops clicking, keeps spinning, gets ready but responds to commands with errors. Maybe this missing component is the source of all troubles. If I knew what it was, I could buy it and solder onto the board. No DR job, so not worth buying identical board.
