Hello,
I have fried a pcb of one HDS721010KLA330, that came out from an iMac.
It has the apple logo and on the label "Apple Firmware 2007"

I have found on ebay a precisely equal pcb, with the same label and same apple firmware notice so i'm guessing that it has been obtained from an imac as well
I've been reading the forum for a while so to my understanding swapping pcbs is not enough but also the old nvram and rom need be installed on the donor pcb

second time lucky, in another post of this forum the nvram and rom where already identified nvram-and-rom-location-hds721010kla330-t10131.html?hilit=HDS721010KLA330#p62192 so it's just a matter of (de)soldering

however i have this doubt that it's preventing me from buying the pcb: is the pcb swap not enough even for apple labeled components? they usually install their own firmware and whatnot proprietary software, so i was *hoping* that by swapping two very identical pcb would be enough.

has anyone dealt with apple hard drives?
thank you very much

You have to provide more details on behavior of your drive.
If your drive does not spin up at all, you should go ahead and try PCB swap.
