Case:
After getting the hard disk, the customer called me to test, and the detection found that the magnetic head was ready.Error judgment of common problems
Solution:
The results of the problem of detecting and processing the problem on the device failed continuously. It is estimated that the problem is wrong. After the test, it is found that the ROM model of a single circuit board is actually busy.Two disks can be used, starting the head change. For the first time, the hungry magnet head of the bad disk was replaced on my good disk. I recognized the big problem. The magnetic head was not bad.It shows that the magnetic head adaptation of the two disks is the same, so I replaced the good head onto the bad disk, haha recognized.The data is completely copied. The original 7mm disk firmware area is very strict with the magnetic head. After copying, we return the data disk magnet head. My accessory disk is still the same as before.
