Hi Guys

I have HTC426030G5CE00 from JVC camcorder, dropped inside water and now the pcb is dead, surprisingly the water didnt manage get inside and contaminate the platter.

The PCB apparently has embedded ROM inside MCU if i am right, please see the attached.

What do you guys think about replacing PCB, will it work or MCU must be replaced? If MCU needs to be replaced i am dead because I could see the MCU shorted by the salt water.

Thanks all.

ROM need to be original most likely
It's native Hitachi not IBM-Hitachi

I hope not many fw variants on this drive.

Can you clean the pcb? There are specific - and expensive! - products to remove fist salt, then sulphate, then oxidization, then clean without residue. If you were lucky enough and no tracks and pads were destroyed, you'll make the drive work enough to image it.

Thanks all, the hdd did not turn on, checked the pcb and found the fuse was blown, replaced and still no power. Apparently customer had turn the camera on when it's wet probably shorted the MCU.

Revision is not the problem
it's HITACHI
and it's adaptives
