SATA 1TB Samsung HD103SI/A. Completely dead.
No shorts between 5v and ground, 12v and ground. Checked TSP diodes across 5v and 12v, no shorts. There is one large 8-pin FET-looking device (maybe the motor switch?), also no shorts.
Other than swapping out the board (and swapping in the original flash memory chip with drive-specific parameters), is there anything worth checking for?
And please, no "It's not worth it" replies. I fix stuff. It's an interesting project.
Thanks.
