Case:
A Seagate hard disk was connected together, and the circuit board interface was burned, so he replaced the entire interface, but still did not recognize the disk, so he turned to us.
Solution:
After replacing the interface, you can add electromagnetic heads normally. There is also a reset sound, but the hard disk cannot be recognized.Under the instructions, I found that there were no prompts. The circuit board was removed and found that there was no welding instructions at all. Important welding instruction lines were used to power up. A lot of garbleds appeared.Carefully checked that there were two resistance at the SATA data cable (there were Yu Xi’s welding here).Use the rosin to clean up the Yu Xi here and power up again. The information under the instruction is finally normal.
