Q&A Problem: How to fix the problem of loud sound of computer hard disk?

The hard disk sounds the first two cases. The hard disk has been used for a long time, or the internal mechanical structure of the hard disk has failed, causing read and write errors to repeatedly read and write to generate noise. The second type is data error. If the file has errors when reading the files, the head will increase the power and read it multiple times. If it is read, it will continue. If it is not read, an error will occur. There is a lot of noise in the process. It is strongly not recommended to cut off the power directly during the working process of the hard disk, which will cause serious damage to the hardware system.
Your problem is likely to be a system software failure, causing the hard disk to repeatedly read the problematic data. The reason for the startup failure is probably caused by this problem instead of the hard disk. If the system can still boot normally, It is recommended to check the hard disk first, then clean up the disk fragmentation, no problem, you can continue to use, or do a brand new system.
