[Office Partner Information Center] Notebook hard disk is the main storage area for notebook data, and the importance of storing data often exceeds the notebook value itself. Nowadays, the security of notebooks talked about by major notebook manufacturers is actually more about the security of notebook hard drives. These are the functions that only high-end notebooks have. We can achieve the same effect by paying attention to some usage items in daily use.
First of all, the hard disk is a very sophisticated storage device. When reading and writing, the flying height of the magnetic head on the surface of the disk is only a few micrometers; even when it is not working, the magnetic head is in contact with the disk. When the hard disk is working, once a large vibration occurs, it is easy to cause the magnetic head to collide with the data area, resulting in damage to the data area of ​​the disc or scratching the disk, and losing the file data stored in the hard disk. Therefore, do not move the computer or move the hard disk before the spindle motor has stopped at work or after shutting down, so as not to cause the head and the disk to collide and scratch the magnetic layer on the surface of the disk.
Secondly, when the hard disk works, it will frequently read and write operations, and the addition and deletion of programs will also generate a large amount of non-contiguous disk space and disk fragmentation. When the number of non-contiguous disk space and disk fragmentation increases, it will affect the read performance of the hard disk. If the data is added or deleted frequently or the software is frequently changed, you should run the disk defragmentation tool that comes with the Windows system at regular intervals (such as one month) to reorganize the disk fragmentation and discontinuous space. Performance is at its best.
Finally, if you often use software with a lot of memory requirements (such as image processing, model design, etc.), you should increase the memory to reduce the amount of read and write operations on the hard disk during a large number of file exchanges, thus extending the use of the hard disk. life. In addition, be sure to use a stable power supply. If the power supply is not pure or the power is insufficient, it will easily cause data loss.
