If the printed circuit board (PCB) of your hard drive is numbered 100588318 is damaged, simply replacing a PCB with the same number may not repair your hard drive. You may also need to transfer the firmware from your old PCB to the new one.
What is the hard drive firmware?
The firmware of a hard disk drive (HDD) is a type of software built into the hardware of the drive itself. It consists of a set of instructions and codes that control various aspects of hard drive operation and functionality. Firmware plays a crucial role in managing data storage, performance and communication of the hard drive with the computer system.
It also contains the unique parameters of the hard drive, such as its model number, serial number, and capacity. This information is used by the computer to properly identify and access the hard drive. Without firmware transfer, the hard drive would not be able to communicate with the computer and the data on the hard drive would be inaccessible.
Where is hard drive firmware typically stored?
A hard drive’s firmware is typically stored on a special memory chip located on the hard drive’s printed circuit board (PCB). This memory chip, often called a firmware chip or ROM chip, contains the necessary software code and instructions that control the operation of the hard drive.
Hard drive firmware is usually stored in the BIOS chip or in the main controller chip. We can find this chip on the old PCB and transfer it to the new PCB to complete the hard drive firmware transfer.
- BIOS Chip: The chip (8 pins, 4 pins on each side) with 25P05VP, 25P10VP, 25F512, 25F1024, 25F1024AN, SST25VF512, SST25VF010, etc. is the BIOS chip.
- Main controller chip: For some PCBs, the firmware is stored on the main controller chip (the largest chip on the PCB). It is more complex to swap the chip. If so, please perform several tests on the hard drive PCBs that do not contain important data.
If you buy HDD PCB from our store, we will clearly mark the chip that needs to be replaced on the PCB before shipping. You can purchase and transfer firmware with confidence.
Tips: Most TV/phone repair shops can offer these transfer services for as little as $5-$20.
