Customer: last Thursday your package arrived and the package looked very promising. I mounted the controler to the drive and checked if it works but unfortunately it doesn’t. I imideatly unplugged the HDD to prevent any damage. In the attachement you can find the pictures of the HDD type and the mount of the controller. Please countercheck if I added the right controller. If so how do we proceede?
Hddzone: Please unscrew the PCB and send the other side photo.
Customer: here you go
Hddzone: You ordered the correct PCB.
You need to move your original PCB’s BIOS to the replacement PCB. The 8pins (4 pins on each sides) with 25P05VP、25P10VP、25F512、25F1024、25F1024AN、SST25VF512、SST25VF010, etc. are the BIOS. You can move the BIOS from your original PCB by using hot-air gun, then solder it on the replacement board. Please refer: http://www.datarecoveryunion.com/hard-drive-rom-chip-swapreplacement/. Or you can find an electronics repair shop help you.
