What is Hard Drive PCB?
The green board on the lower part of the hard circle drive is known as Printed Circuit Board(PCB). The primary capacity of the PCB is to supply capacity to the hard drive, keep up speed and turn of the axle, and control all inside tasks through its firmware. Basically, PCB is the minds of the hard drive that all parts are vigorously needy upon.
Why Swap PCB Boards?
Hard plate drives that don’t turn up after the force has been provided can be analyzed as PCB disappointment. Since information recuperation administration is extravagant, now and again we would want to trade them ourselves.
How to locate the coordinating HDD PCB sheets?
Western Digital – same board number which is carved on the PCB, start with 2060-
Seagate – same board number which is carved on the PCB, start with 100…, and a similar Main Controller IC. On the off chance that you can’t locate the number on the PCB (Old Models), you should locate a similar Main Controller IC.
Maxtor-same Main Controller IC(The greatest chip on the board)
Hitachi-same data on the little white mark (initial two lines)
Samsung – same board number which is scratched on the PCB, start with BF41-
Fujitsu – same board number which is scratched on the PCB, start with CA
Hard Drive PCB Swap Process:
Eliminate the PCB from both hard drives with star screwdriver. Supplant the harmed PCB with substitution one. In the event that you HDD turns up, yet can’t be remembered, you ought to likewise trade the BIOS chip on it. In the event that there is no coordinating 8pins BIOS chip on the PCB, it implies the BIOS chip is incorporated on the Main Chip IC, at that point you should eliminate the harmed double layer pcb Main Chip IC to the benefactor PCB. It is more intricate to trade the Main Chip IC than trade the BIOS chip. On the off chance that you ought to do, kindly do a few test on the PCBs which don’t have the significant information.
What is PCB’s BIOS Chip?
The entirety of the 8pins (4 pins on each sides) with 25P05VP, 25P10VP, 25F512, 25F1024, 25F1024AN, SST25VF512, SST25VF010, and so on are the BIOS chip. It is anything but difficult to be found in light of the fact that there are relatively few 8pins chips on the board.
As a rule, you should trade the BIOS before you trade hard plate pcb. You ought to have certain method.
Note: You should know the hard drive disappointments are not generally brought about by PCB disappointment, trade PCB can’t ensure to fix the entirety of the hard drive issues.
