Computer hard drive loud how to solve

Computer hard drive loud how to solve

One, hard drive bad road

This is the most common cause of a hard disk squeak, and in many cases the hard drive is broken, which can be cleaned up by a disk Cleanup program or other proprietary software to fix it.

Second, mechanical problems

Sometimes the hard drive is in use, will suddenly "when" ring, and then can not continue to read and write data, or even restart the computer in the BIOS can not find the hard disk, the more common is just when the hard disk is used normally, but when the hard disk use one or two hours later, suddenly appear above phenomenon.

Reason: Hard disk in reading and writing data, spindle motor high-speed rotation, control chip under the control of the drive arm to carry out the corresponding action, to complete the data reading and writing operations. Spindle motor high-speed rotation in the constant speed of work, if the hard disk power supply voltage changes too large, will cause a change in the speed of the hard disk, then will appear magnetic arm positioning is not correct or wrong, resulting in no normal reading data or hard drive bad road increase.

Failure Analysis: The hard disk circuit board and the hard disk body of the magnetic arm power supply interface caused by poor contact. The hard disk circuit board and the disk power supply phase part is not the use of pins or flexible cables, but the use of crimping, because the hard disk for a long time, coupled with poor working environment, circuit board interface Tin oxide, plate spring plate oxidation, resulting in poor contact between the two, resulting in the magnetic arm seek motor power supply instability, and appear to seek abnormal, The hard drive is not working properly.

Troubleshooting: The solution is also very simple, open the fixed circuit board four screws, remove the circuit board, up to pick up the circuit board, in the circuit board interface side will have two rows of spring, we need to be careful with the use of sandpaper will each spring piece of contact polished. At the same time, the corresponding contact points on the circuit board should also be polished, and then the circuit board can be loaded back. notebook computer, if it is your computer, it is best to take advantage of the three packs of time, a new better.

Third, the voltage is insufficient

The hard drive needs a steady voltage and sufficient current supply to work. If the voltage is not stable or the supply of current is not enough, it will appear difficult to find, hard disk "ka" straight, or can not find hard disk or data read difficult, it may be shown in the process of the hard drive suddenly lost, the data can not read and so on. The higher the configuration of a notebook computer, the higher the power requirements of each component, and the more likely it is to have a laptop than a regular desktop because of its limitations.

These two situations are usually the power of the switch power supply that our computer uses is insufficient or have trouble to be able to appear afore-mentioned circumstance. For power supply +5v and +12v voltage instability, we can use the multimeter test to judge. Too high and too low are not good, generally within 10% fluctuations can be considered normal situation. For the power supply to provide a shortage of current situation, we can according to their own host of the hard disk, optical drive and related configuration to calculate the full load of the power required to work, and we use the power of switching power supply compared. In general, the power supply should be greater than 10% of the maximum power of each component, but not the same.

Four, the hard disk control chip damage

Unlikely because the hard drive is usually less faulty than the computer accessories, unless subjected to larger shocks.

If it is found that the use of the computer hard drive loud, a squeaking sound, then you can refer to the above mentioned content to troubleshoot and solve.
