Daily maintenance rules for computer hard disks under Windows

1. Do not turn off the power while the hard disk is being read or written. When the hard disk is being read or written, the disk is in a high-speed rotation state. If the power is forcibly turned off at this time, the magnetic head and the disk will be violently rubbed, thereby damaging the hard disk. Therefore, when shutting down, be sure to pay attention to the hard disk indicator on the panel to ensure that the hard disk is closed after reading and writing. 2. Keeping the environment clean and dirty If the dust is too much in the working environment, the dust will be absorbed on the surface of the hard disk printed circuit board and inside the spindle motor. Operating the hard disk in a humid environment can cause insulation resistance to drop. These two phenomena can cause the computer to be unstable, and some electronic devices may be damaged, or some dust-sensitive sensors may not work properly. Therefore, it is necessary to maintain the sanitation of the working environment and reduce the amount of dust in the air. In addition, the user can not open the hard disk cover by himself, otherwise the dust in the air will enter the disk, and the possibility of scratching the disk or the magnetic head during the read/write operation of the magnetic head will be greatly increased, so the hard disk is never allowed to be in the ordinary condition. Remove the disk housing screws underneath. 3. Preventing vibration The hard disk is a very sophisticated device. When working, the head has a flying height of only a few microns on the surface of the disk. When not working, the head is in contact with the disc. When the hard disk is being read or written, once a large vibration occurs, the magnetic head may collide with the data area, causing the disk data area to be damaged or scratched, or even losing the file information in the hard disk. Therefore, it is strictly forbidden to move the notebook computer greatly before the hard disk spindle motor has been shut down during work or shutdown, so as to avoid the impact of the magnetic head of the hard disk and the disk, and scratch the magnetic layer on the surface of the disk. 4. Preventing the effects of environmental humidity and magnetic fields When using a laptop in a wet season, care should be taken to dry the environment or to constantly power up the system, and to evaporate the water vapor from the machine by its own heat. In addition, try not to bring the hard disk close to a strong magnetic field, such as speakers, speakers, motors, radios, etc., so as to prevent the data recorded in the hard disk from being damaged by magnetization. 5. Prevent computer viruses from damaging the hard disk Computer viruses are a big threat to the data stored on the hard disk. Therefore, you should use the newer anti-virus software to perform regular virus detection on the hard disk. If you find the virus, you should immediately remove it. Try to avoid formatting the hard drive because hard drive formatting will lose all data and reduce the life of the hard drive. When copying information from a foreign floppy disk to the hard disk, first perform a virus check on the floppy disk to prevent the hard disk from being infected with the virus. The size of a reasonable partition hard disk partition seems to be not very related to the maintenance disk, but the reasonableness of the partition is closely related to the future maintenance, upgrade operating system
and optimization, and must not be ignored. . Setting the appropriate partition size at the beginning will save you a lot of unnecessary trouble and facilitate future management. 7. Clean up disk fragmentation For some users, disk defragmentation seems to be a must-do every day, but if the system's virtual memory is placed in a separate partition, then Windows
system Generated Win386. The SWP will be generated in successive blank clusters, and this is the case every time. Therefore, disk fragmentation caused by virtual memory does not exist, which eliminates a large source of disk fragmentation. Moreover, since the impact of fragmentation on audio and video file playback is almost negligible (play speed and quality depend on the memory buffer settings and CPU capabilities), if the user does not write and delete files in large quantities, generally only the C drive is browsed. The device will generate disk fragmentation (the default path of the system. If it is changed, the partition where the temporary file is buffered should be defragmented). The rest of the songs MP3, video and game partitions, one month or even two months to sort out. Because the speed of the system depends on the partition of the operating system, as long as the system files of the C drive are kept tidy, the data structure of other partitions has little effect on the system speed and stability. Of course, if users also store files that are frequently edited or modified in other partitions, they should also be sorted frequently. 8. Try not to use the hard disk compression technology. When the hard disk space is small, we always try to save the hard disk space. The common method is to compress the hard disk space through the Doublespace and Drvspace commands, but when the compressed volume file is gradually increased, this method There is a very obvious shortcoming, that is, the speed of reading and writing data on the hard disk is greatly slowed down. With the rapid development of hard disk technology, the capacity of the disk is also climbing, so it is difficult to find that the hard disk space is often not enough, and we do not need to use hard disk compression technology. 9. Backing up the hard disk partition table Backing up the hard disk partition table and checking the integrity of the backup is also very important for protecting the data on the hard disk. Because the Windows operating system is broken, it can be reinstalled. If the hard disk partition table is broken, the system will not recognize the hard disk. The problem is much more serious. We can use the tools such as KV3000 or Ghost to back up the entire Windows system partition into a file and store it separately. When the hard disk is faulty due to a problem with the hard disk partition table, rewrite it to the C drive. Furthermore, after two or three months of use, the newly installed Windows system is optimized almost anyway. It is almost impossible to maintain the original speed. If we back up the entire Windows system partition, we will periodically It is ok to write to the C drive. In short, backing up a partition and overall Windows state can solve more problems than simply backing up several registry core files separately, and the operation is relatively simple.
