If the seek error rate is low, the hard disk reading speed will slow down. Seek error is one of the physical faults of hard disk mechanical system (solid state disk does not have this problem), which cannot be eliminated by software repair and can only be repaired or replaced.
Extended data
When reading data from the hard disk, the read-write head moves radially above the track where the sector to be read is located. The distance between the starting position and the target position of the pickup head is different, and the seek time is also different. After the head reaches the designated track, the sector to be read is transferred to the lower part of the read-write head through the rotation of the disk.
Hard disk seek error is the behavior of reading and writing tracks. This kind of error prompt will lead to the decline of head positioning accuracy, which will lead to the decline of hard disk reading and writing performance, and even lead to the decline of hard disk reading and writing performance in serious cases. There is no way to locate. The possible reasons for the seek error are the aging, problems or other reasons of the head servo system.
