Hi Everyone

Western Digital
WD3200KS
WD Caviar SE16
MDL: WD3200KS-00PFB0
26 AUG 2006
DCM: DHCACAJCAN
WD P/N: WD3200KS-00PFB0
PCB: 2060-701393-002 REV B
PCB Sticker: 2061-701393-800 AE

PCB damage as shown. I've ordered a replacement board, and i'm 98% sure, but i thought i'd ask anyway, the U12 chip is the one i transplant right?

Does anyone know if the motor/heads might be damaged from this?

Cheers,

U12 yes is the one to move
Motor damage, not likely
Heads maybe

The damage is on the motor side, most likely due to an overvoltage on the 12V supply, in which case the preamp will probably have been untouched. Measure the resistances between the motor terminals just to be sure.

There must have been some really bad cabling around this drive if so much current flowed through the sata shielding... :o

@CleanestRoom, this article shows you what happens when the overvoltage is on the 5V side:

Solder job went okay.

Plugged drive in, it started spinning unlike before then...

click, click, click, click, click, power down. The entire time the BSY registry was turned on.

I guess this means the heads or pre-amp is destroyed?

I guess i should also tell the customer to get a new psu or surge protector board. :S

I have no idea what's going on with my pictures. :lol:

PC3K support had a look at it. Tried some different head map configurations, then some different utilities, then a custom loader..

Final diagnosis is head failure or media damage.

Case closed! :mrgreen:
