Hard disk is a very special one PC accessory, the value of its own is not large (less than the current hard disk capacity of 160G 600), but hard data on the carrying value is an accurate figure can not be measured. In particular, in accordance with the current hard disk capacity, most of the computer users are using more than 100G products, high-capacity hard disk storage of huge amounts of data, it also has a very obvious reason: If your hard disk problems, then all data would have lost the risk of hard disk carrying the greater amount of data, it means greater losses, especially in the disk array, data recovery costs are far more than the value of the hard disk itself.
Of course, for ordinary users, the data seems to be no commercial value. But this does not mean that ordinary users of the data can freely Diushi, for example, that certain users have collection of photos, movie clips and some personal information such as diaries, once lost, Sui Ran seems little direct economic losses but Zhexie information for the users may be very valuable; In addition, it will be hard problems in a certain period of time the system down, causing trouble should not be ignored. According to survey, PC system failure more than 20% chance is caused by the hard disk, so the daily care and maintenance work on a larger significance, and the correct use and maintenance can not only drive longevity, because of data loss and to remove more annoyance and even economic losses.
The internal structure of the hard disk
Although the external structure, all there is a certain difference between the hard disk, but its internal structure is basically the same, after all, the essence of hard work will not change. The core section includes an internal hard disk drive body, spindle motor, read-write heads, Seeker motor. But need to remind you that, do not open in the general environment of free hard disk case, because the internal hard drive can not be tainted with the dust disk, or immediately scrapped.
Road maintenance drives
In fact, on the PC to carry out normal maintenance parts and maintenance, then it must understand the characteristics of their components, in particular, there is harm to its operations must understand, so you can avoid the lines of. We can separate the characteristics of the hard disk maintenance.
1, a fatal weakness - shock
Hard drive are mechanical products, vibration can be said that the sworn enemy of a big hard drive, hard drive internal structure is very sophisticated, heads of thousands per minute transfer from the disc surface, only a few microns in height, once the shock, then there will be more intense reading was caused by abnormal or even physical disc or head injury, very serious consequences.
Hard disk reading and writing are forbidden move: in fact do not work hard in the circumstances, can survive a certain collision, or the drive can not be carried to all over the world. But when hard at work, can withstand the vibration is very small, small vibrations may lead to higher disaster. Especially for the DIY users, like the PC series of events, often of convenience to do with a computer to operate, so that when hard at work moving, this is undoubtedly a very dangerous operation, ranging from loss of data, and at the end of life to the hard disk directly. So we must bear in mind that when hard at work, can not move operation.
Chassis and hard disk can not have resonance phenomenon: Hard at work is in a stable rotating state, such as the current mainstream PC hard drive is 7200 rpm. In a regular rotation with the PC when the hard disk may be in the same chassis resonance point, this way, the hard disk will be in a shaky state, although the amplitude is small, but over many years in this state, then the damage to the hard drive is large, the evolution of quantitative change to qualitative change will eventually lead to hard problems. We can increase the hard rubber pad and other methods to avoid the situation of resonance with the chassis, while also reducing hard drive and chassis resonance and the noise.
First prepared about four 1 mm thick, that crustaceans the size of rubber pad, rubber pad and then use scissors in the middle of the opening, as long as the drive screw to pass through can be. Next, the hard disk drive rack mount chassis, note cards at the same time to the hard rubber pad between the frame and hard drive and hard drive to open the mouth and alignment of the fixed screw mouth. Finally, drive the screw can be tightened through the rubber pad. Alternatively, you can use to produce a flexible rubber strip suspension, which is hard to use rubber strips to hang below the hard drive bracket, thus avoiding the rigidity of the hard disk and bracket connection, thus avoiding the resonance noise.
Computer desk must be stable: the majority of PC users are using the computer desk (or desk) to place the computer. However, the importance attached to the computer desk is not enough, design or poor quality of the computer desk in use long after the phenomenon will have sway, especially in the larger rock when the user typing, for game users, in the fierce When fighting, computer desk calendar will be more rock damage; while some users prefer the use of computers keep their feet away from moving the computer desk, these are very detrimental to the operation of the hard drive. Therefore, we recommend users to buy a computer desk desk perfect material when you use the product, must also use the computer not to develop the habit of shaking the table.
Other: In the interim connected hard drive, try to be flat wrong, preferably fixed on the hard disk bracket, it should not hang in the chassis. Many users think that just a temporary swap data, put the hard disk not leave. In this case, hard side of the read and write data, while in the shaking, the damage on the hard disk becomes evident. The other is the hard drive is best not to put in the work of the provisional state drive, the drive read the disk when the shock is large, and even can be placed on the hard disk drive vibration displacement, so the damage on the hard disk is quite obvious.
2, the sworn enemy of hard drives - high temperature
Hard drive capacity constantly increasing, in which the disc density, the number of sheets and the speed of the disc are to move forward. However, the temperature has been the hard drive manufacturers are one of the difficult headache. Because of this, 7200 still remain the mainstream consumer market, speed, lasted for several years had not even a smooth transition to a low-cost high-capacity 10,000 rpm hard disk up, which heat is a problem. Of course, the hard disk itself, the heat issue can only be resolved by the manufacturer, the user can do to improve the hard drive can only use environment, specific precautions are as follows:
To be enough hard disk space up and down: Hard at work will continue to heat, then the user can do can only be allowed to disperse heat. Most of the heat the hard disk is lost through the top and bottom to, so the upper and lower hard disk space must be left enough so as not to shut down the hard disk space. Many users, when installing dual hard not to consider this, or is the chassis is not enough space to install, took two hard drives installed very close to the location so that the heat on the hard drive is very unfavorable.
Chassis cooling air channel to pay attention: In many cases, the heat inside the chassis are not valid if the excluded, then the temperature of all the PC components will follow the rise, naturally, including the hard drive. So the chassis air duct design can not be ignored, a good duct design will effectively reduce the temperature inside the chassis, and thus to effectively drive heat dissipation.
Duct design to improve matters here is not more narrative, and to remind everyone of the point is not simply that the use of the chassis fan will certainly effective heat dissipation. To be used with caution chassis fan, fan can be placed in proper position to play its due role, otherwise there may be counter-productive situation. For most of the chassis, the installation of additional cooling fans is not only no good, and easy way interfere with the wind, resulting in poor heat dissipation. Therefore, the cooling box to ensure smooth, apart from the fan into the front chassis, rear or top exhaust fan is necessary, is in fact reasonable as long as we build the internal chassis air duct, fan of other locations can not.
Do not air-conditioned environment in the summer time non-continuous use PC: hard disk to use from the start the day, it had already begun its long slow process of aging. Prolonged use of the hard drive, then drive the accumulation of heat will be rising, as not all users have used a good duct design, so the heat and the hard disk given the heat may not be equal, so for a long time After running the hard disk will be increasingly high temperatures, causing failure. Generally speaking, we better not use the PC more than 24 hours continuously, especially in the summer, non-air-conditioned environment, if we really have to continuous use, I suggest open the chassis, with a large cooling fan on the chassis to cool down the whole operation.
3, other harsh environments to minimize the use of PC
In fact, not only temperature, vibration, has a great influence on the hard drive, a number of other harsh environment of the hard disk of the injury can not be ignored. Such as low humidity, strong magnetic fields, dust and larger venues such as voltage instability. The following hazards were to look at them.
Humidity damage: humidity into absolute humidity and relative humidity, absolute humidity is per cubic meter of air contains water vapor quality; relative humidity is saturated water vapor in the air, the degree of saturation to 100% RH. When the absolute humidity at constant temperature, the smaller the higher the relative humidity. In fact, most people think that humidity is too high on the hard drive would be more harmful, does not. Because the hard disk drive body is very good precision sealing components, and humidity will not be any harm, and has been on the humidity in the factory have adaptive testing; and hard on the circuit board are SMD components, SMD One advantage is that components less sensitive to moisture and humidity will not affect work; another hard drive interfaces are the oxidation of the measures has been done, nor excessive humidity will not be oxidized to cause contact bad and so on.
But in fact afraid of the hard disk is too low humidity, in fact, dry environment. In the winter, when dry, often with a static body, if the environment in the carpet even more so. When human exposure to the hard disk or the chassis, the ESD threat to the safety of the hard disk, hard disk chip can withstand the voltage is not large, so in low humidity environments when using the PC, the body must touch the ground to pay attention to the object before and PC contact, in order to prevent electrostatic damage to PC accessories.
Hazards of electromagnetic interference: in fact most of the magnetic material parts are subject to strong magnetic field interference. Here is a simple example, we previously used tape, the head is carried out with a strong magnetic record washing operation. Hard also has a similar reason, it is best not to drive in a strong magnetic field of the environment. For example, in the high-power speaker subwoofer will produce a strong magnetic field, even though manufacturers have repeatedly claimed to be magnetically shielded design, but as long as you get testing equipment to detect what will know that this is no small shielded the water, and speaker magnetic leakage in the course of the opportunity still at stake. For example, a number of other high-power electric motor type of products will generate strong magnetic field, these products should be maintained with 1 meter or farther.
Dust hazards: dust has always been PC accessories chronic killer, how many parts there is the strange problem caused by dust. The same is true on the hard drive is concerned, although the hard disk drive body is tight, but the hard surface of the circuit board near the office and the spindle motor if excessive dust absorption, then, it will also damage to the hard drive, so the PC is larger if the dust environment work, the user should pay attention to dust work well on a regular basis.
Voltage fluctuations damage: Voltage instability is a major killer of hard drives, data surprise loss, the system can not find the hard drive, etc. One reason is the strange phenomena caused by voltage fluctuations. Where voltage fluctuations in two cases, one is unstable mains voltage itself, where more than 46 cities and some of the mountainous areas. If electricity unstable, then it is best on their own power supply with a voltage regulator, on the whole computer can be equipped with a UPS power supply, not only can play the role of regulator, but also for the PC to ensure continuous power supply during power failure , hard at work to prevent a sudden power-down. In other cases, PC power supply voltage instability, some of poor quality or shrink the power supply (the actual power supply is too small) will occur, the user as long as good quality power supply can be replaced. In addition, the user equipment attached too much if it will lead to lack of PC power supply to cause voltage instability, this time on the need to replace the power of the higher power.
4, it is recommended to ensure the system has 512MB of memory
Windows operating system virtual memory mechanism is a very important initiative. The proceeding has now run the growing memory needs, is a QQ chat software, the memory is also quite a lot, let alone large-scale image processing software. If the PC physical memory small, the operating system will allow the hard disk as virtual memory to supplement memory is not sufficient to ensure normal operation of the program. This will undoubtedly harm the hard drive, while the speed of the system also allows users to worry is very, because the hard disk speed and memory speed difference compared to if it is too far too.
Current mainstream operating system is Windows XP, To let it run too smoothly, then, 256MB of memory is to low demand, but when run the program, then more, 256MB of memory is not enough, it is recommended users upgrade to 512MB of memory to ensure system operation speed, while the hard drive is also a very favorable protection program, to say the memory is very cheap now, this investment should not be provincial.
5, hard disk operating habits Note
Read and write data to avoid frequent
To work hard from the start the day, is constantly began its long aging process. Read and write data operation is its quantitative factors in the aging process, so read and write operating frequency, then the hard disk will increase the aging process and even some of unpredictable problems, which points to note are as follows:
Not 24 hours BT download: This does not mean that BT download what the hard drive itself, aggravated assault, but to BT download speed and download content on the hard drive is a large burden, such as downloading a TV series, may be more than 10G, download the seed number is not stable, so the download speed will be affected, often requires users to download within 24 hours continuously, and even a few K / sec to download data on tens of G, so the frequency hard to read and write, but also continuously without interruption to work, drive the aging rate and the probability of problems is increased on the positive.
Defragment the hard disk do not frequent the transition: the system in use for some time, will produce more hard disk file fragments, the larger impact on the speed data access to speed up the aging process of the hard disk. Many users use the system's own Disk Defragmenter to organize a large scale. This measure is good, but we must be careful not to over-frequent, otherwise it will backfire. Because the Disk Defragmenter on the drive itself is frequently read and write operations, if the frequent use of this operation, then, will accelerate the aging process and even damage the hard disk drive. Recommended once every two months, finishing the disk, reinstall a system of six months, this is the most effective way to improve system speed.
Minimize the use of PC hard disk as a server: Since it is the server of course better to use the server components, the ordinary PC hard drive is not designed for servers, but also used in ordinary PC inside, hard disk protection measures for all servers no. As a 24-hour work server, normal PC hard drive is not bear the high intensity of upload and download services, so ordinary users or less is best set up in their own 24-hour server, unless you are prepared to replace a hard drive a year.
Do not power off the hard disk read and write data
Hard drive read and write operations not only can not move, but not power. Although the hard drive manufacturers have done a variety of security measures, but the sudden loss of power for operation on the hard disk or a historic problem, experience has shown that a sudden power failure is likely to result in hard physical injury, this is not just lost data, some physical damage may not recover, so the user must pay attention to avoid the hard disk read and write data in power.
Also, do not frequent switching power supply, and some DIY user injury during some tests, to always switch machine. Such as PC problems after going to the commonly used methods for detection of hardware PC, then unplug the power supply should be hard, otherwise the head would frequently drive through "take off" "landing" process, which certainly increased the damage to the hard disk probability, so we must pay attention.
Do not use hard overclocking
Some users love DIY overclocking, the temperature high enough to not only the CPU, graphics card overclocking, even the hard disk is also overclocking. In fact, this is a very good operation. Hard drive performance after overclocking is very limited, but the resulting harm is considerable. Hard disk and CPU, memory, different, it is the mechanical body parts, after the hard disk when overclocking instability phenomenon, its performance against the direct loss of data, which are CPU, memory is not as losses. Data is priceless, the user is best not to use this method of overclocking worth the wait.
Institute of hard disk damage shield
Hard disk damage is a historic problem, this situation is no longer after the low-cell commonly used method, because hundreds of G's hard to endure the operation, then it is more cruel. In fact, we can use hard disk damage shield to prevent the proliferation of ways to reduce its loss. And when the partition bad sectors to be ruthless snack area, divided into more space, not to small and lost big. In addition, my proposal in bad sectors hard disk inside the data should always be backed up, after all, is a patient, the backup to solve data loss is the safest solution.
