The seven taboos for the use of mobile hard disks

Mobile hard drives have become an important device for data interchange by virtue of their large capacity, high speed and portability. For this reason, the probability of problems in use is also large. More. Many users have encountered various problems in storing and reading data while using a mobile hard disk, causing various losses. Here Xiaobian will explain to you some of the contraindications of mobile hard disk use, I hope that you can reduce the occurrence of problems during use.

1, the hard disk can not suddenly shut down when working

When starting work, it is generally in high-speed rotation. If we suddenly turn off the power in the middle, it may cause the head and the disk to rub sharply and damage the hard disk. Therefore, it is best not to shut down suddenly. When shutting down, be sure to check whether the hard disk indicator on the panel is still flashing. Only when the hard disk indicator stops flashing and the hard disk ends reading and writing, the computer's power switch can be turned off.

2, to prevent dust from entering

Dust damage to the hard disk is very huge. This is because in a dusty environment, the hard disk can easily attract dust particles in the air. The attracted dust accumulates in the internal circuits and components of the hard disk for a long time, which will affect the heat dissipation of the electronic components, making the circuit board, etc. The temperature of the component rises, causing leakage and burning the component.

In addition, dust may also absorb moisture and corrode the electronic circuits inside the hard disk, causing some inexplicable problems. Therefore, the dust volume is small, but the damage to the hard disk cannot be underestimated. Therefore, it is necessary to maintain environmental sanitation and reduce the humidity and dust in the air. Remember: General computer users cannot open the hard disk cover by themselves, otherwise the dust in the air enters the hard disk and scratches the disk or the magnetic head during the reading and writing operations of the magnetic head.

3, to prevent excessive temperature

Temperature has an impact on the life of the hard disk. When the hard disk works, it generates a certain amount of heat, and there is a heat dissipation problem in use. The temperature is preferably 20 to 25 ° C. If the temperature is too high or too low, the clock frequency of the crystal oscillator will change. The temperature will also cause the circuit components of the hard disk to malfunction, and the magnetic medium will also cause recording errors due to the thermal expansion effect; if the temperature is too low, the moisture in the air will be condensed on the integrated circuit components, causing a short circuit.

When the humidity is too high, the surface of the electronic component may adsorb a layer of water film, oxidize and corrode the electronic circuit, resulting in poor contact or even short circuit, which may change the magnetic force of the magnetic medium and cause data to be read and written. error. If the humidity is too low, it is easy to accumulate a large amount of static charges generated by the rotation of the machine. These static electricity will burn out the CMOS circuit, absorb dust and damage the magnetic head, and scratch the disk. The humidity in the equipment room is preferably 45-65%. Be careful to keep the air dry or to constantly power up the system, and evaporate the water vapor inside 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, mobile phones, etc., so as not to damage the data recorded by the hard disk due to magnetization.

4, to regularly anti-virus hard disk

The scope of the current virus attack is more and more extensive, and the hard disk as a computer information storage base, usually the first choice for computer virus attacks aims. Every year on April 26th, every computer user has a lingering fear. Several hard drives on the unit have been attacked by CIH. Therefore, in order to ensure the security of the hard disk, we should pay attention to the use of the latest anti-virus software to kill and kill the virus, while paying attention to the protection of important data and regular backup.

5, be careful when holding the hard disk by hand

In daily computer maintenance work, it is more frequent to take the hard disk by hand. Perhaps the most common thing that can't attract our attention. In fact, it is still a matter of learning to take the hard disk by hand. A little carelessness will also make the hard disk "discard". Therefore, we should grab the hard disk when holding the hard disk and avoid direct contact with the circuit board on the back. Some types of hard disks will be covered with a protective film on the outside. In addition to the shockproof function, the protective film protects the circuit board, so that we can not worry about static electricity.

6, can not move the hard disk at work

Hard disk is a high-precision device, the flying height of the head on the surface of the disk is only a few microns. When the hard disk is in the read/write state, once a large vibration occurs, the head may collide with the disk and cause damage. So don't move the running microcomputer. Care should be taken during the installation and disassembly of the hard disk. When the hard disk is moved or transported, it is forbidden to bump. It is best to protect it with foam or sponge to minimize vibration.

7, the biggest taboo is accidentally fell, followed by plugging and unplugging when running!!

The life of the mobile hard disk or the use time of the mobile hard disk is a comparison Concerned, for this study, you can effectively improve its service life. Do not know, you noticed that, as long as you pay attention to use, be careful to keep it, at least for more than 5 years. The power-on time should be no less than 30,000 hours for the standard calculation.
