Hello

I have a Maxtor DiamondMax PLus 9 160GB:
YAR41BW0
K,M,B,D
Y45PB8PE
6Y160P0042811
One day, i switched +4 and +12 V cables (yellow and red) and the PCB burned under my eyes
I wanted to retrieve my data and ordered
http://www.hdd-parts.com/18000270.html but now the hard drive makes some some "click, click, click" sounds and is not seen by the bios.
Do you know where the problem comes from ? (bad PCB, bad firmware... ?)
Thank you
