Western Digital WD10EAVS faulty - please help

[jaseandwave]

This WD WD10EAVS 1Tb was in a WD MyBook but it stopped working, no noise, no smell just as dead as a dodo.

Upon testing the power supply I found it was supplying 20V instead of 12V, so I guess this is the cause.

I'd like to get a similar logic board and replace it but apparently you need to swap the U12 ROM chip. My board has not got a U12 ROM chip so any ideas would be appreciated.

Also I've removed diodes D3 and D4 (I read that this might work) but still no good.

Ideas please!

Nothing you can do without specialist tools on this one I'm afraid, the ROM info is inside the MCU (chip with the "M" on it).

A new PCB need to be "manufactured" with the correct ROM info, which can be rebuilt using the ROM images on the platters.

PM me if interested.

Hi, Did you check r67 as it looks like a fuse?
