Details to Swap Hard Drive Printed circuit board

What exactly is Hard Drive PCB?



The green board within the bottom of your really hard disk drive is called Printed Circuit Board(PCB). The primary perform of your PCB should be to provide power for the tough drive, keep pace and rotation in the spindle, and control all internal operations through its firmware. In essence, PCB may be the brains from the hard drive that all parts are heavily dependent upon.



Why Swap PCB Boards?



Really hard disk drives that don't spin up soon after the energy continues to be supplied might be diagnosed as PCB failure. Simply because information recovery support is extremely costly, in some cases we'd desire to swap them ourselves.



The way to locate the matching HDD PCB boards?



 Western Digital - exact same board amount which can be etched over the PCB, start off with 2060-

 Seagate - same board amount which is etched within the PCB, start with a hundred..., as well as similar Major Controller IC. When you can not uncover the number around the PCB (Outdated Designs), you need to obtain the identical Principal Controller IC.

 Maxtor- similar Most important Controller IC(The biggest chip over the board)

 Hitachi- same information on the little white label (first two lines)

 Samsung - similar board quantity which is etched on the PCB, begin with BF41-

 Fujitsu - same board variety that's etched about the PCB, commence with CA



Hard Drive PCB Swap Course of action:



Take out the PCB from the two challenging drives with star screwdriver. Change the broken PCB with substitute a single. Should you HDD spins up, but can't be recognized, you must also exchange the BIOS chip on it. If there may be no matching 8pins BIOS chip within the PCB, it indicates the BIOS chip is integrated to the Principal Chip IC, then you definately should really take out the broken PCB's Major Chip IC on the donor PCB. It is far more complex to exchange the primary Chip IC than exchange the BIOS chip. If you ought to do, please do quite a few check over the PCBs which never possess the critical data.



What's PCB's BIOS Chip?



Every one of the 8pins (four pins on every sides) with 25P05VP, 25P10VP, 25F512, 25F1024, 25F1024AN, SST25VF512, SST25VF010, and so on. are the BIOS chip. It is uncomplicated to get observed mainly because there are actually not quite a few 8pins chips within the board.



In most situations, you ought to exchange the BIOS ahead of you swap tricky disk pcb. You should have selected method.



Note: You'll want to know the challenging drive failures will not be constantly brought about by PCB failure, swap PCB can't promise to repair every one of the challenging drive difficulties.
