Seagate Barracude 7200.10 burnt motor cont. chip

[TerraNova]

I have a burnt motor controller chip on Seagate Barracude 7200.10, 500Gbytes
Replaced the SMOOTH and blew up again.

Is it sufficient to get the drive working by swapping the ROM with the same model to donor drive? or model and firmware must be the same?

Thank you

The ROM on the board does not contain adaptives, so it will not help you to swap it.

You need to find a PCB with a similar MPU, as the ROM information is embedded in the processor.

hi Jono, "You need to find a PCB with a similar MPU", you mean same model and firmware?

MPU is the Main Processor Unit....aka cpu

That's a good place to start, but no guarantee. I just tried a board swap on a Seagate with the same model and firmware. However, the site codes were different (same country!) and the actual FW was different enough that the boards would not match!
