Hard disk fault judgment, how to judge that the hard disk is faulty

Your hard drive is broken, this situation is estimated to be unrecoverable, if you can find a professional data recovery company for insurance.

Bad road, take it to the store where you used to assemble your computer for warranty!

Here's how to tell if a hard drive is faulty

1. The magnetic head is damaged: the self-test cannot be passed during the boot self-test, and the hard disk emits a regular snapping and snapping sound because it cannot be found;

2. The motherboard is damaged: If the motherboard of the hard disk is burned out, the most common manifestation is that there is no response after powering on. If it is a laptop hard disk, you can close to the hard disk to listen to whether it rotates, and you can also observe whether the components on the board have obvious burn marks;

3. Hard disk bad sector: The phenomenon after the hard disk has bad sectors is that the system starts slowly, or can enter the system, but there will be fewer partitions or some partitions can not be opened, pie book laugh or can open partitions and some folders can not be opened;

4. The hard disk body is damaged: the phenomenon is that the hard disk reports an error after the boot POST, and it is required to press F1 or press del to enter the CMOS setting;

5. MBR damage: the current posture is the loss of information;

6. Partition table loss: Partition table will be lost.

If fixing(D:)Stage 1 occurs, the D drive is faulty.

The failure of the hard disk is generally divided into pure hardware failure and software failure, relatively speaking, the hardware failure caused by the software is more complicated, because the hard disk involves system software and application software, but the solution is sometimes very simple, sometimes all the problems are gone after restarting or reinstalling the system!

Hardware-only failures are trickier. Hardware failures can be divided into system-caused, such as loose IDE interfaces of the motherboard, incompatibility with other hardware devices, unstable power supply, etc., and the other is the failure of the hard disk itself, such as bad sectors, partition table corruption, viruses, etc.

Symptoms of bad sectors appear:

a. When reading and writing hard disks, the screen often prompts information such as "Sector Not Found" or "General Error in Read-ing Drive C".

b. The system cannot be booted through the hard disk when booted, and the floppy disk can be turned to the hard disk letter after booting, but it cannot be entered, and the system can not be successfully booted with sys commands (such as displaying non-system disk, etc.).

c. Reading a file or running a software often makes mistakes, or it takes a long time to read successfully, during which the hard disk keeps reading the disk and makes a harsh noise. This phenomenon means that some sectors of the hard letter matching disk that contain data are broken.

d. When using the computer normally, there is often a black screen or blue screen inexplicably.
