What are the symptoms of a bad hard drive?

How do you know if your computer hard drive is broken? What are the symptoms of a bad hard drive? The following article will introduce to you the common symptoms of hard drive failure. I hope it will be helpful to you.

The symptoms of a broken hard disk are:

1. The system has a blue screen, prompting relevant error codes.

#2. The BIOS cannot recognize the hard disk, or even if it can recognize it, the operating system cannot find the hard disk.

This is a sign of physical failure of the hard disk, so the data should be transferred out immediately and then inspected and repaired.

There are many reasons why the hard disk cannot be recognized. Common faults include bad sectors, firmware damage, head/motor failure, circuit board burnt, etc.

3. The hard disk makes a "click-click" sound.

This is the most intuitive feeling after the magnetic head is damaged. Normal hard disk will also make a weak sound when it is working, but it needs to be distinguished in an extremely quiet environment. This is a normal phenomenon and users do not need to worry. However, the sound produced when a hard disk head is damaged can be heard even in a noisy environment.

4. The hard disk sends out a beep beep beep alarm.

This situation is often caused by the magnetic head not returning to the landing zone normally and parking on the disc, causing the motor to lock up and emitting an alarm sound. At this time, the hard disk does not rotate.

5. The hard disk does not spin when turned on or spins for a few seconds and then stops spinning.

The hard drive's failure to spin up is usually caused by motor or circuit board failure; the hard drive's automatic stop is often caused by the head being damaged and automatically stopping to protect the disc, which is common in Seagate and Samsung hard drives.

6. Files will be lost on the hard disk, and the ScanDisk program will automatically start to scan the disk when the computer is turned on, prompting for error repair.
