At the picture, you can see the pins of the Marvell chip go to the other of the board through some vias.

At the other side of the board, follow the traces and you will see they pass through two pairs of capacitors, then connect to the bridge chips ( the one near the usb connector ) .

You will remove those 4 capacitors, and connect the sata connector wires to the empty pads, at the side that goes to the Marvell chip.

For this one-off job, no need to use other resistors/capacitors in circuit. But keep the wires short and neatly arranged. You can find many other threads here about the same procedure with a discussion about the importance of the cabling.

Connect the usb cable normally, to give power to the disk

Hi everyone! I manage to get the data out of the drive!
I were able to solder a usb cable directly to the pcb.

Here a picture of the finished work.

Thank you all for the help!
