Hi everyone

I was hoping someone may be able to offer some advice on a HDD that has failed which has a lot of family photos on that I’m trying to recover.

This drive is out of a portable HD unit. It failed due to using a wrong power adapter. I have tried to run it off a Caddy and it would not power up or spin. I since ordered another HD to try and salvage the PCB off it to see if that would fix it. Fitting the new PCB does make the HD run and spin up but it does not 'chirp' as normally heard when reading data. It makes a couple of tick noises like the reading arm is hitting the stop constantly and then turns off.

I have noticed that the replacement HD I bought has slightly different part number and firmware version and also the board is slightly different:

Seagate ST3500418AS
P/N: 9SL142-568 FW: CC34 vs 9SL142-302, CC38

Could this HW or FW difference affect it booting up? Or can the HD be setup so that the caddy is unable to boot it since its designed to be operated by the original HD controller (which I still have but I’m reluctant to use it since it could also be damaged from the power adapter)?

Any feedback would be greatly appreciated.

Did you transfer ROM too?
