HDD PCB White Label

The circuit board (PCB) is an important part of the hard disk. There are some important components or parameters on the circuit board, such as “White Label Number”, “Board Number”, “BIOS Chip” and “Main Controller Chip”, etc. This article will mainly introduce the “White Label Number”. The white label number is very important, because if our hard disk circuit board is failed or died, to find a suitable replacement circuit board, we need to make sure the white label numbers are the same. The number of the white label is the most important parameter should to be considered. To find a replacement circuit board for Hitachi 2.5” hard drives, we should to make sure the replacement board and your original board have the same white label number.

To find the correct white label number on the PCB, you’d better to use a T6/T8 screwdriver to unscrew the hard disk.

Note: Even we have found the correct replacement PCB, we also need to swap the BIOS chip from the original PCB to the replacement PCB to let the hard disk be recognized. To transfer firmware on PCBs, please refer to: HDD PCB Firmware Transfer
