What's the number on that one? Can't see it on your photo. Also that part may just be a TVS?

Hi,
U can remove/replace Transil D3 (SMAJ5.0A), and replace resistor R67...

90% that's a TVS....remove it and power on..

The marked part is a TVS.
Remove it, and poweron alone (without the HDA) and use a FUSE in the 5V circuit.

If you are lucky the marvell mcu still good.

I think you should replace it ( not remove it ) for your safety

you don't know what will happen again

maybe if you remove it and power on directly that will burn MCU


Good luck

This is why i sad, use a FUSE in the 5V line....
The TVS is only for transient filtering and overvoltage protection.
Generally it is safe to remove, but not for long use again!

Hi,

Thanks to all,

I have remove the TVS and just connect the PCB and always BSY, can not also enter in safe mode.

No no no Zebong!
You don't need same PCB
The donor PCB should match:
xxxx-701552-xxx xxx
xx xxxx xxxx x xxxxxxx x xxx

Only those 6 symbols are important for matching.

This is ABSOLUTELY EXACT information, you MUST know it, otherwise how are you still working in data Recovery???


P.S.
I've done some researches on WD and solved ABRT problem, when you have no access to userdata, but SA looks fine...

Hi Creator,

This works in all WD disk ? or just for the marvel ?
I try this is Cyl 16 did not work

Thanks

some old WD drive had this info messed up, so it might not work on old WD drives. But on old WD drives it is easy to ID the PCB by looking on layout
