Have a westeren digital wd5000lmvw that i change pcb on And moved u12 from old to new. After replacing will not the hard driver spin up.. it will spin up with the wrong u12 but only give like click of dead. Any suggestions for a newbie
I use DFL-PCIe 4X Data Recovery Express. I’m actually not sure how to read rom I turned off the hard drive when the click of dead start (won’t damage reading head? ) original pcb is dead I think no light no spin up.
I have tried "donor" ROM on original pcb and original ROM on donor pcb hard drive is still dead. I have also tried and take a backup of bios from patient hard disk with ROM reader, but I can not read it off, so I think there is nothing to do with this hard disk?
Even if the ROM is totally dead, which is pretty rare, it's certainly not a lost cause. It's just a matter of either rebuilding the ROM from the service area (if there are backup modules there) or finding a close enough ROM to work. I've often found that a drive built within the same week will have a close enough ROM code to work.
