HDD Chip Sets

Hi

It's the right firmware as it came from the faulty drive being transferred to an identical logic board.

But you don't need to do this, the problem is the drives media not the logic board or firmware.

If the drive has reached the point that you can't access any data now you should now get a data recovery professional to recover any more data or write the drive off.

Could it still be the ROM chip?... Or, would the board not work with a faulty ROM chip.

Or it could be a bad resistor, or a bad capacitor. Or even a hairline crack in the circuit bard.

The possibility of damage by comics rays has not been ruled out yet.

So the bottom line is that if I can get some data off of a failing hard drive then there is no point in even considering a replacement of the logic board or ROM.  You are saying it is on the inside of the drive and a problem most likely on the plate(s).

Thank you.  Consider my questions answered.  Thanks for all of the great information.

The OP said "At least with the old chip set, I could extract some data using a data recovery program.  " which means it wasn't the logic board that was the issue.

Exactly. It would seem the OP believes the chip  set reds different parts of the Hard drive surface. Not true. Yes,  any modem HDD may have two heads, but a basic electron device switches between the two heads. The rest of the demodulation and data extraction is done by a common set of electronics. If a large amount of data can not be found, it is more likely the head has failed and not the electronic switch. The switch is a very basic device. The flying head is a very delicate electromechanical assembly often subject to a hard life.
