Common trouble of hard disk and its elimination method

In the actual work, the hard disk is not often the problem of accessories, the normal use of the hard drive can generally maintain five years of work time. And most of the hard disk failure is caused by bad, the solution is to use special software to find out the hard drive of the bad road and hide the period mask.

In the actual work, the hard disk is not often the problem of accessories, the normal use of the hard drive can generally maintain five years of work time. And most of the hard disk failure is caused by bad, the solution is to use special software to find out the hard drive of the bad road and hide the period mask. In many cases, check out the machine hard disk failure, often due to improper settings or other factors caused, here I introduce two examples of more common hard disk failures and troubleshooting methods:

First, the data line caused by bad contact with the hard drive failed to identify instances of troubleshooting

Failure phenomenon: The school network classroom of a student machine, the recent often appear can not boot or after the boot is not able to find the hard drive, through careful examination, after the boot can hear the hard disk disc rotation sound, the system detects boot device when prompted cannot find hard drive. The machine model is: Intel 810 motherboard, Intel Celeron 1.1GHz processor, 256M DDR266 memory, hard disk for Seagate Cool Fish 7200.7 40GB.

Restarting the machine or going into the CMOS reset is all right, but it is often restarted during use, and the hard drive cannot be found after reboot. The beginning of the failure is not serious, but also can be used, but with the increase in the number of uses, failures more and more frequent, so decided to completely solve.

Failure analysis and resolution: According to the normal overhaul sequence, first to the hard disk thoroughly antivirus, with the latest version of Jiangmin and rising after killing nothing, basically ruled out the virus to destroy the boot zone and partition table May. Then began to suspect that the CMOS battery aging led to hard disk sometimes unrecognized, replaced a new battery after the failure is still. According to the symptom, if the software is not a problem, then see the fault from the hard disk itself, is not the quality of the hard drive, because it is in the computer room, each machine configuration is basically the same, this gives the replacement method to bring convenience, the hard drive and another computer interchange, the results of two computers unexpectedly did not appear problem! This is strange, does the hard disk and the motherboard still have compatibility problem? Absolutely impossible, the boards of both machines are one model, all Intel's original 810 chipset motherboards.

Ruled out the hard drive itself after the fault, because the network classroom each computer has its own name, and the IP address is also different, in order to facilitate management, the hard drive and changed back, the result of the fault again to find.

Baffled, how did it go wrong again? Think about it, in addition to the exchange of hard disk when plugged in the data line, the other places did not move, is the data line there is bad contact phenomenon? So hurriedly put a new 80 core data line, the result all normal. After one weeks of testing, it was confirmed that the failure was completely eliminated.

Failure Summary: The main reason for this failure is the 80-core data cable after multiple plugs, because the line diameter is finer, there is the phenomenon of bad contact, and in the overhaul of the two computers swap hard disk, the contact with the bad place, wait until the time to change back again disconnected, resulting in a recurrence of the failure.

To this end, readers are reminded that if you use a hard drive that is still the IDE, then you pull the data line when the movement must be light, be careful, can not be very random at once to pull down the data line, the IDE and the hard drive of the data cable plug very tight situation, it is easy to cause data line Plug and the contact between the core line undesirable phenomenon.

Second, hard disk cooling caused the computer repeatedly restart or blue screen troubleshooting

Failure phenomenon: Friend Reaction, his one purchase for more than two HP notebook, recently always inexplicably repeated restart or blue screen crash phenomenon. The specific performance of the fault is: After the computer, about the normal use of four hours, the computer will be inexplicably restarted, starting again after the continuous use of one hours of time, the computer will automatically restart again. Restart phenomenon is not bad, sometimes in the use of a direct blue screen crash phenomenon, so that friends feel very annoyed, because of the free maintenance period, so find the author to help solve.

Fault analysis and elimination: The friend of this notebook maintenance is good, although there are two years, but looks quite good. Friend Introduction: The use of the book is quite careful, the fault appeared in two weeks ago, according to a friend of the fault, the basic judgment is due to poor heat caused. Open a friend's computer and let it work one hours later (running a simple application), touch the surface of the fuselage with your hand, and find the special heat when the hand touches the part where the hard disk is placed. Notebook hard disk installation should be more obvious than other parts of the heat, but as hot as a friend of the first time to see, not to mention this only work for one hours.

So the notebook opened, carefully observed for the hard disk cooling fan, found that the fan did not rotate. Such a high temperature fan is not reflected, it is no wonder that often restart and panic. Find the root cause of the problem, go to the market to buy a new type of radiator switch on, open notebook detection for seven or eight hours, there are no problems, to solve this problem.

Fault Summary: We all know that the notebook on the thermal requirements of the high, especially the hard disk, the calorific value is significantly larger than other parts, due to the limited size, so in the heat dissipation is generally not very good. Friends used to use the machine has never been used for four hours, and then also in the winter, recently because of the more busy to use the computer, but inadvertently found this fault, I believe this is not accidental bar. So remind friends, if you encounter a frequent restart and blue screen crash phenomenon, you may wish to think more from the heat.
