So I had a 750 seagate barracuda HD in PC. Connected through a Raid controller. Just storage HD, the OS is on a seperate HD so PC boots up fine
Few days ago I noticed that itspartitions were not showing up. Raid showing no device detected.
So I thought maybe raid controller was bad, bought new one and same result.
I figure the drive is dead. Ive tried searching on ways to fix it long enough to copy data off it. Read about replacing the PCB.
Im wondering if I track down the same exact PCB, same firmware, manufacture date same everything. What are my chances of success?
I ordered a new HD and an external HD enclosure. When they arrive I will pull dead HD out and put new HD in. Then I will put the dead one in enclosure just to see if it powers up, as I cant hear it while its in the case. Im want to wait for new HD so that I have somewhere to copy the data aonto
If its just dead, I am thinking of trying the PCB fix.
I see you can send it in to a pro for hundreds of dollars but who wants to spen $700 or whatever on that.
If the drive doesn't spin up, or attempt to spin up, then the PCB is most likely at fault. When replacing the PCB, be aware that most modern HDDs store unique, drive specific "adaptive" information in a serial EEPROM chip. This chip, or its contents, needs to be transferred from patient to donor, ie a straight PCB swap won't work.
The following PCB suppliers offer a firmware transfer service, either for free, or for US$10:
I would advise that you avoid those suppliers who don't tell you that a board won't work without modification. Often they will attempt to obscure the requirement for a firmware transfer by deceptively describing their products as being "for data recovery only".
Alternatively, if you are not adept at soldering, your local TV/AV repair shop should be able to transfer the chip for you.
