Specifics to Swap Hard Drive Printed circuit board

What is Hard Drive PCB?



The green board over the bottom with the tricky disk drive is called Printed Circuit Board(PCB). The key function from the PCB is to provide energy to your difficult drive, retain velocity and rotation on the spindle, and management all internal operations through its firmware. Essentially, PCB is the brains on the tricky drive that all elements are heavily dependent upon.



Why Swap PCB Boards?



Difficult disk drives that don't spin up following the electrical power has become provided could be diagnosed as PCB failure. Since data recovery services is extremely highly-priced, often we'd prefer to swap them ourselves.



Tips on how to locate the matching HDD PCB boards?



 Western Digital - very same board quantity which is etched within the PCB, start with 2060-

 Seagate - same board variety which can be etched about the PCB, begin with one hundred..., as well as the very same Principal Controller IC. Should you can't come across the variety to the PCB (Outdated Versions), you ought to uncover precisely the same Key Controller IC.

 Maxtor- same Most important Controller IC(The biggest chip on the board)

 Hitachi- identical facts over the modest white label (first two lines)

 Samsung - similar board number that is etched around the PCB, start off with BF41-

 Fujitsu - identical board amount and that is etched on the PCB, start off with CA



Hard Drive PCB Swap Procedure:



Remove the PCB from each tricky drives with star screwdriver. Substitute the broken PCB with substitute one. When you HDD spins up, but cannot be recognized, it is best to also exchange the BIOS chip on it. If there is certainly no matching 8pins BIOS chip about the PCB, it means the BIOS chip is integrated over the Most important Chip IC, then you definately should really clear away the broken PCB's Main Chip IC towards the donor PCB. It can be a lot more complicated to exchange the main Chip IC than exchange the BIOS chip. Should you ought to do, please do many test about the PCBs which do not have the significant information.



Precisely what is PCB's BIOS Chip?



Every one of the 8pins (4 pins on each and every sides) with 25P05VP, 25P10VP, 25F512, 25F1024, 25F1024AN, SST25VF512, SST25VF010, etc. would be the BIOS chip. It can be quick to be uncovered since there are actually not several 8pins chips about the board.



In many scenarios, you need to exchange the BIOS ahead of you swap tricky disk pcb. You need to have sure technique.



Note: You'll want to know the really hard drive failures will not be always triggered by PCB failure, swap PCB can't assure to fix each of the hard drive challenges.
