Advice 1: For what reasons can fly hard disk

Hard disk — a storage medium which is installed on the computer operating system and software. Therefore, when the failure of the hard disk with the operating system, the computer loses the performance.

Warranty period of operation of computer hard disk drives (HDD) can be 36 months, however, sometimes the drives fail after a couple of months after purchase. In some cases faults can be fixed easily, and all the information on the media fails to restore. And there are times when failure is unavoidable.

Faulty hard drives



All the faulty HDD can be divided into two categories: software and hardware (mechanical). In the first case, faults can usually be resolved at home with the help of specialized software. And in the second case, you must contact the service or warranty Department of the store (with a valid warranty card).

The most common causes of faults



As for the hardware failures, they can be a result of the breach of the conditions of operation of the drive and the computer in General. For example, the computer may not be placed in hot and humid areas, put it near a radiator. Hard drives are "afraid" shock and vibration, so they need to fix in the system block. When removing or installing the hard drive in the enclosure must be carefully not to drop the disc, as from a blow on the floor and other surfaces it can fail.

Mechanical failures can cause the sudden power outage or a sudden voltage drop in the power grid. Therefore, the use of uninterruptible power supply (bespereboynik) allows you to extend the lifespan of your hard drive. As soon as the tension head of the hard drive can damage the surface of a magnetic disk on which information is recorded.

Software malfunctions too often arise through the fault of the user, most often they cause experiments by logical partitions. They can also be caused by any computer virus. To avoid software malfunction, hard drive, it is recommended not to turn off the computer by such methods as pressing the power button on the case and pulling the power cord from the outlet. This can not only lead to program failures, but also to mechanical breakdowns.

It also happens that the carrier has a manufacturing defect. So it some parts prematurely fail. When the disk audible clicks or crackling, it is better to take it to the warranty Department. In such a situation you should not wait until the drive stops working. If it is a defective copy, then after the examination you will be given a healthy new disk.

Advice 2 : How to repair a Winchester

Winchester is one of the most important parts of any computer. It contains all the information that is usually very important and necessary to the user. In case of breakage of the Winchester the person may lose much more than ten times the cash value of the disc.
How to repair a Winchester
Instruction
1
If the computer does not see the hard no apparent reason, the first thing do is unplug the computer from AC power and perform General cleaning inside the case, pay special attention to the adapters and connecting wires (cables). This is fairly common problem when dust accumulates in the connectors of cables, and certain parts cease to function. Winchester in this case is no exception. Remove it from the system unit, then carefully clean and dry each adapter and the input on the Winchester. Now connect it back and restart the computer.
2
If such cleaning does not work, again remove the hard drive, figured take a screwdriver and Unscrew the screws holding the cover on the drive and remove it. Check that there are no cracks, chips or other obvious damage on internal circuit. If outwardly all is in order, do a thorough cleaning of the inner parts of the hard drive and connect it to the computer on completion.
3
If the computer does not see the hard drive, regardless of whether or not there were any defects in the disk or not, go to the service center on repair of computers. Most likely, the repair will not be denied, and moreover he is likely to end in success, but be prepared for the fact that the cost of repair may be comparable to the cost of a new hard drive. For this reason, if the warranty has expired, and particularly important information on the hard drive are not available, think about whether the repair costs.
4
If you refused to repair, and info on the hard drive is important to you or the road, try to find Amateur specialists on the Internet. So, some programmers often offer help with data recovery from "dead" carriers. Of course, that's no guarantee of the reliability of this method, but if there's no other choice, you should try this method.

Advice 3 : How to repair a hard drive yourself

Causes problems with your computer can be a huge amount. If you have not loaded an operating system, or you have to reinstall, think about the need to test your hard disk. Due to voltage drops in the mains suffers from the health of hard drives, and they gradually (and some immediately) fail.

  • - Live CD.
Instruction
1
Take a drive LiveCD any Assembly. Such discs can be bought in shops that sell various movies, games, software. It is also worth noting that the images of such systems are no problem to find online and burn to disc. Be sure all check downloaded files with antivirus software since viruses can get into your system. Importantly, the disk contained a program to test hard drives from different manufacturers. Boot the computer from an optical disc, putting the right priority in the Boot section of the BIOS and motherboard.
2
Run the program to test the hard drive. For example, Victoria will give information about the status of the hard drive and will test it for the presence of BED-sectors. Bad sectors is a sign that Winchester is out of order. Usually this program scans your hard drive for a few hours, and the time depends on the size of the disk, so you have some time to wait.
3
If the program found bad sectors, use the utility hard drive recovery. For example, the utility HDDRegenerator testing the hard drive and immediately corrects found BED sector. Upon completion of the program displays the number of corrected bad sectors. Repeat the procedure again in a month. If bad sectors are found again, it is likely that Winchester will have to change, so as to store information (and especially to install) do not.
4
If your house is often flashing lights or turned off altogether — install an uninterruptible power supply. Due to power surges not only can you lose data on your hard drive, but also deprived of basic parts of a computer power supply and motherboard.

Advice 4 : How to identify a faulty hard drive

Hard disk drive (HDD) is one of the main units of the modern computers, along with motherboard and device input and output. And at the same time the HDD is very fragile and unreliable mechanism due to the fact that has a significant number of moving parts. Timely diagnosis can help the user to avoid problems such as physical destruction of the HDD and data loss, recovery of which is often impossible even for an expert.

You will need
  • A special software.
Instruction
1
Pay attention to the nature of the work HDD. In some cases, there are visual changes that are "thought" hard drive, its periodic "freezes". The computer fan works in all and almost never turns off. Or, on the contrary, it is not noticable at all. In this case, you need to check the HDD temperature with the help of special software. Suitable software quite a lot, for example, you can use the services of Everest. Not recommended to touch the part of the computer case and laptop where is the hard drive, because you can get burned.
2
Install the program and spend monitoring the temperature of the HDD, which should not exceed 45 degrees Celsius. If the value is greater need to inspect the fan and clean the fan grille dust-free to HDD cooling was effective. It should be noted that overcooling of hard drive leads to failure, so the installation of an excessive number of coolers may result in damage and stopping the HDD.
3
After processing the temperature data, run the utility S. M. A. R. T., which allows to evaluate the state of the hard disk of the computer. In the process of testing the S. M. A. R. T. checks are critical to HDD performance parameters, such as: Raw Read Error Rate, Spin-up time, Uncorrectable Sector Unit and many others. Found S. M. A. R. T. defective sector are presented to the user in the report on the test results.
4
After the detection of bad-sectors download from the Internet and install it on your computer one of the many utilities for HDD diagnostics, which is free to access. Professionals recommend such as HDDScan, HDD Health or HD Tune. If the test with the help of this software will reveal a large number of bad –sectors, independent attempts to save the data from the disk will only worsen the situation. In this case, it is strongly recommended to use the services of specialists.
5
Try to copy the contents of the HDD before it stops working completely. Use a special program for data recovery. One of the best is EasyRecovery. There are other utilities, but they are less known. It should be especially noted that the data recovery process is possible only in a small number of the affected sectors of the HDD. If a lot of them, the hike in service cannot be avoided.
