If the Service Track cannot be read, the Read / Write Head will be reading along its axis. Then it will go to Parking without reading.
(2) A part of the read/write head is bent.
(3) If it bends like this, the next time the head will rub against the surface.
So how can this be prevented?
This is one of the common denominators. It tells you what happens over time. What is the Electronic Component of a Hard Disk? Below the hard disk is a small circuit board. The circuit board is damaged due to an electronic failure of the hard disk. The reason is clear. Because of Power. When voltage is not stable. In the event of a voltage surge, whatever happens, is electrical. This usually results in physical damage to the circuit board. I’ve seen a lot of hard disks like this before. The good news is that the circuit board can be removed and replaced. Data does not end there. But even if you make a mistake you may lose data. About mechanical breakdown and breakdown.
