The second link has been messed up by the closing bracket.
As for your board, I have been through this with another individual. In his case the MCU was shorted. Hopefully you will have better luck.
The first thing I would do is to confirm that there are no shorts on any of the supply rails. To this end you would need to measure the resistance between each supply and ground. In addition to the +5V and +12V supplies at the SATA power connector, the board generates its own internal supplies from several switchmode DC-DC converters, and one linear regulator. One is the Vcore for the MCU, another is the -5V for the preamp, and there are either one or two Vio supplies for the MCU, SDRAM, and serial flash.
Could you measure the resistance between ground (at the SATA power connector) and each of Vio and Vcc in this photo clip?
Also measure the resistance between ground and pin #1 of the SDRAM:
Determine which of the following 20 pins are connected to ground, and which is connected to +5V:
Also determine which of the preamp pins are connected to the Voice Coil Motor (VCM) sense resistors, R8 and R9:
Here are the onboard DC-DC converters:
Measure the resistances of each resistor (R48, R45, R47), each inductor (L), each capacitor ©, and each diode (D). Also measure the resistance between the non-striped end (anode) of diode D2 and each pin in the preamp connector. The pin that measures 0 ohms will be the -5V supply.
Also measure the resistance between each L and ground.
Finally measure the resistance between each of the leftmost two inductors and each of the SDRAM and serial flash supply pins.
These measurements should map out the layout of the onboard supplies, and identify which components are powered from each supply.
