After the firmware transfer is completed, the repair process is finished! Connect your HDD to your PC and restart your computer, you will be able to recover data from your HDD now! Backup! Backup! Backup!

About Hard Drive PCB Components:

BIOS: All of the 8pins (4 pins on each sides) with 25P05VP,25P10VP,25F512,25F1024,25F1024AN,SST25VF512,SST25VF010, etc. are the BIOS. It is easy to be found, because there are not many 8pins chips on the PCB.

Main Controller IC: If there is no matching 8pins BIOS chip on the PCB, it means the BIOS is integrated on the Main Controller IC. It is more complex to exchange the Main Controller IC than exchange the BIOS. If you should do, please do several test on the HDD’s PCBs which don’t have the important data.

About Firmware Transfer Tool & Steps:

HDD PCB Firmware Transfer Tools:

• Hot air rework station;
• T6/T8 Screwdriver(available on HDDZone.com product page);
• Tweezers;

Steps to transfer firmware on the PCB:

1. Remove BIOS chip from the original PCB;
2. Remove BIOS chip from the donor PCB;
3. Solder the original BIOS chip to the donor PCB;

Tips: Most of the TV, phone, electronics repair shop can offer this firmware transfer service for just $5-20.

Step 3: Firmware Transfer on PCB boards
In most cases, you need to transfer the “BIOS” chip (HDD firmware are usually stored in the “BIOS” chip) before you swap hard drive PCB, in order to make the donor board compatible with your HDD.

Step 4: Recover and Backup Data
After the firmware transfer is completed, the repair process is finished! Connect your HDD to your PC and restart your computer, you will be able to recover data from your HDD now! Backup! Backup! Backup!

About Hard Drive PCB Components:

BIOS: All of the 8pins (4 pins on each sides) with 25P05VP,25P10VP,25F512,25F1024,25F1024AN,SST25VF512,SST25VF010, etc. are the BIOS. It is easy to be found, because there are not many 8pins chips on the PCB.

Main Controller IC: If there is no matching 8pins BIOS chip on the PCB, it means the BIOS is integrated on the Main Controller IC. It is more complex to exchange the Main Controller IC than exchange the BIOS. If you should do, please do several test on the HDD’s PCBs which don’t have the important data.

About Firmware Transfer Tool & Steps:

HDD PCB Firmware Transfer Tools:

• Hot air rework station;
• T6/T8 Screwdriver(available on HDDZone.com product page);
• Tweezers;

Steps to transfer firmware on the PCB:

1. Remove BIOS chip from the original PCB;
2. Remove BIOS chip from the donor PCB;
3. Solder the original BIOS chip to the donor PCB;

About Hard Drive PCB Components:

BIOS: All of the 8pins (4 pins on each sides) with 25P05VP,25P10VP,25F512,25F1024,25F1024AN,SST25VF512,SST25VF010, etc. are the BIOS. It is easy to be found, because there are not many 8pins chips on the PCB.

Main Controller IC: If there is no matching 8pins BIOS chip on the PCB, it means the BIOS is integrated on the Main Controller IC. It is more complex to exchange the Main Controller IC than exchange the BIOS. If you should do, please do several test on the HDD’s PCBs which don’t have the important data.
