Hi

Can anyone tell me the location of the Nvram and Rom chip on this board. I know what I think but thinking isn't good enough; I want to know :wink:

Drive is a Hitachi HDS721010KLA330 1TB

Certainly looks like it. One TVS/diode removed, another one played with!

Thanks everybody. I thought as much

I know the history of the board. The missing TVS was pretty much blown in half, the other has just been lifted. I know a soldering pro who's got all the hot air stations and stuff. We are going to move these chips to an identical donor board that I have already obtained. The data is not that important so we may as well have a go.

just to make things more fun, when the TVS was removed etc. what happened when you power the disk on? How does it sound? nothing at all?
