Why swop Hard Drive PCB?Hard drives that fail to spin afterthe power has been supplied can be diagnosed as PCB failure meaning faultyhardware. Since data recovery service is very expensive, sometimes it is preferableto swap PCB instead of changing entire hard drive or getting data recoverywhich costs a fortune.How to find the corresponding Hard DrivePCB boards?Western Digital - same board number which is imprintedon the PCB, begin with 2060- Fujitsu-same board number which is imprinted onthe PCB, begin with CA***Seagate - same board number which is imprintedon the PCB, begin with 100 , and the same Main Controller IC. If you cant findthe number on the PCB (Old Models), you should find the same Main Controller IC. Maxtor same Main Controller IC (The biggestchip on the board)Samsung-same board number which is imprinted onthe PCB, begin with BF41-Hitachisame information on the small whitelabel (first two lines)Hard Drive PCB swop Process:Remove the PCB from both harddrives with star screwdriver. Replace the damaged PCB with replacement one. If theHard disk spins up, but cant berecognized, next step would be to exchange the BIOS chip installed on the hard drive. BIOS chip is a 8 PinBlack Color CHIP installed on the hard drive. If there is no matching 8 pinsBIOS chip on the PCB, it means the BIOS chip is incorporated on the Main ChipIC, then you should remove the damaged PCBs Main Chip IC to the donor PCB. Itis more intricate to exchange the Main Chip IC than replace the BIOS chip. Ifyou should do, make sure you do it on the CHIP with no data or else you are atthe risk of losing data which would diminish our purpose of replacing PCB tosave the data.What is PCBs BIOS Chip?The BIOS chip normally comes inthe form of a rectangular DIP (Dual In-line Package)or a square PLCC (PlasticLeaded Chip Carrier) package. The capacity of BIOS chips ismeasured in Megabits (Mb). Most BIOS chips these days are 2Mb (256KB) in size.These higher capacity chips allow the manufacturer to offer more features thanis possible with the smaller 1Mb chips.All of the 8pins (4pins on each sides) with 25P05VP, 25P10VP, 25F512, 25F1024, 25F1024AN,SST25VF512, SST25VF010, etc. are the BIOS chip. It is easy to locate the CHIP sincethere are not many 8pins chips on the PCB. In most cases, you should swapthe BIOS before you swap hard drive pcb.Where to buy hard drive pcb online?There are many online stores from where you can buy PCB for your data recovery needs!. They provide all kinds of PCB: Seagate, Western Digital, Maxtor, Samsung, IBM, Hitachi and Fujitsu. They can always help you to find the marching PCB for your hard drive.Note: One thing to note is not all hard drive failures are result of PCB failure and it is not certain that swapping hard drive pcb would fix hard drive, it is one of the reasons of hard drive failure
