Use this hard drive PCB to replace your old hard drive's failing PCB. Please make sure that you match the model of the hard drive, PWB, and PCB sticker. Hard Drive is not included with board. Please note that if drive is not working after PCB transfer that means you most likely need to transfer the ROM chip from the old board to the new board as it contains unique information that is required for the hard drive to operate. Transferring the ROM off the PCB board may cause permanent damage to the ROM and make your data unrecoverable. It is not recommended to do this unless you are trained to do this type of transfer. Fujitsu hard drives and Seagate hard drives with dot "." in firmware generally do not require firmware transfer. Firmware version on your hard drive label or our "PCB Specification" list is NOT firmware version of the PCB; matching it doesn't mean you will not need firmware transfer.
