When the PCB is dead, what are the symptoms of the hard drives? The patient hard drives will keep busy and not detected, the motor will not spin up and users can do nothing on the PCB and hard drives.
When the PCB is dead with corrupted ROM,engineers need to swap the PCB or need to solder the ROM chip if there’re external ROM chips for the damaged hard drives. Usually most new hard drives have external ROM chips.
To swap a PCB requires the users to search from the self-owned PCB donor archives or buy new donor PCBs to continue the job and it takes time and money to do this one. However, if users can solder the external ROM chip, read the chip and write new donor ROM resources to it, solder it back to the PCB and then the PCB works again and the hdd can be ready for further repair and data recovery.Dolphin Data Lab offers a large database of WD ROM resources or users can use the DFL-WDII hdd repair tool to regenerate the original ROM once the hdds can be entered normally and become ready even the hdds are not detected.
