In view of the different fault performance of different brands of hard drives, it is necessary to separate them, but in any case, the hard drive that is not rotating is almost certainly a problem with the board, and rarely the motor is broken.

1, the performance is stopped after the transfer (fine diamond 1, 2 generation), not the problem of the circuit board, is the fw error, rewrite can be.
2, the performance of the parameter is disordered, shown in system configurations as none, ibid.
3, the performance of the boot self-test stays in the test hard disk for a long time, but can correctly identify the hard disk id, the system capacity can display the correct capacity, 0 bad.
4, the performance is that the system has not been able to enter the system for a long time after the boot, the hard disk has bad sectors (system problems are not discussed).
5, the performance of cmos can be correctly identified, but after the self-test shows 'pri Detect Fail', the fault is the same as 1.
6, the performance of the boot self-test in the detection of the hard disk for a long time, and can not identify the hard disk id, feel the head action, the head is bad or fw error.
7. There is abnormal noise after starting up, you can hear the sound of bang, the head or the circuit board is faulty.
8, self-test model is garbled, and the capacity displayed in system Configurations does not match, the board is faulty (data line issues are not discussed).
9, le disk will appear in the loop recognition disk, but also fw error, rewrite can be.
Fujitsu dish
1, the performance is normal, but the boot self-test model is garbled, and system Configurations shows no, fw error, rewrite.
2, the performance is normal, the self-test model is correct, the system Configurations display capacity is also correct, but can not perform disk operations under dos, such as fdisk, dm, lformat, etc.; fw error, correct.
3, the performance of the boot self-test stays in the test hard disk for a long time, but can correctly identify the hard disk id, can display the correct capacity in the system Configurations, 0 bad, special instructions - this fault is very easy to lead to failure 1, need to send as soon as possible repair.
4, the performance is that the system has not been able to enter the system for a long time after the boot, the hard disk has non-zero bad sectors.
5, the performance of the hard disk when the boot disk, the circuit board or the head or fw problem, this fault repair rate is relatively low.
6, the performance is not recognized when the time, the board and fw problems.
7, the performance of the use of Dangdang, circuit board or fw problem.
Ibm disk
1. The performance is humming when the power is self-tested. There are two possibilities. The first is the bad zone of 0; the second is the poor contact between the circuit board and the hard disk, which is the so-called circuit board shift problem.
2, the performance is that after the boot, the hard disk stays for a long time, and the hard disk is not detected, but the hard disk is activated after the power is on, the loder problem, some need to rewrite fw.
3. The performance is not detected by the power-on self-test, there is no head movement sound, but there is a rotation, the head problem.
4. The performance is that the motor does not rotate smoothly after power-on, and the circuit board or motor has problems.
5, the performance of the magnetic head back and forth after power-on, circuit board or motor problems.
6, the use of the process of buzzing, the hard disk has a bad area.
7. Some hard disks have buzzing and squeaking sounds, which are head problems.
