The server needs to record and read data all the time. This process also has a great deal of connection to the hard disk of the server. The hard disk is a main storage space of the server and stores all the data in the server, but the hard disk appears. The chance of failure is also very high. Here we describe in detail some of the common performance of the server hard disk failure, if any of these conditions occur, you can perform related troubleshooting for the hard disk.

In general, there will be a series of performance before the hard disk fails:

1, fault prompts. That is, we often say that the hard drive self-monitors and analyzes error reports. When a control head, disk, circuit and other components collide with a pre-stored security value, a warning message will automatically occur. When this failure prompts, we will take the lead and analyze and deal with it as soon as possible.

2, the hard disk does not recognize. At startup, from time to time, the display hard disk cannot be recognized, or even if it can be identified, but the system shows that the hard disk cannot be displayed. This is a precursor to physical failure. At this time, we need to transfer important data and conduct inspection and maintenance.

3, system operation error. During the operation of the server, the status of program errors constantly appeared, and the disk scan problem was stagnant or even crashed. This time, on behalf of the hard disk failure, of course, it may be because of the installation system failure, after we eliminate software problems, we can determine the hard disk failure, the need for maintenance.

4, running error. Scan the disk, find errors, and even show bad sectors. This time, it means that there are problems with the hard drive components and bad sectors have appeared. We need to isolate them to ensure normal use.

5, initialized crashes. Initialization is deadlock, although it does not rule out the possibility of other parts of the problem, such as memory problems, fan problems, system poisoning, etc., but most likely because of the problem of hard disk failure, the need for correlation analysis.

The above is a description of the common performance of server hard disk failures. Although the server will perform related maintenance when renting the server, it is an essential skill for the server administrator to grasp the server's failure performance and handle it. Of course, the failure of the server is not only aimed at the hard disk. For example, the CPU, memory, etc. are also a high incidence of server failure. We will introduce relevant contents for these contents.
