How to handle a hard drive that is not recognized by your computer

Hard disk in use, because of natural aging or improper operation and other reasons, there may be a variety of failures, the computer does not recognize the hard disk, is one of the most common failures. Because of the large amount of data stored on the hard disk, the risk of data loss is faced once a failure occurs. So, how do you deal with a computer that doesn't recognize a hard drive to avoid data loss?
The failure of hard disk can be divided into pure hardware fault and software fault. Relatively speaking, because the hard disk involves the system software and application software, the software caused by the hardware failure is more complex, but the solution is sometimes relatively simple, such as the main boot sector was illegally modified to cause the system can not start, abnormal shutdown caused by the logical bad path, generally by re-partition format can be resolved.
Hardware failures include head damage, circuit board problems, chip information loss, motor not rotating, etc., the most intuitive phenomenon is to enter the motherboard BIOS settings, the hard drive is not recognized. We can see through the eyes of the circuit board whether there is a chip burned, with ears carefully listen to the start of the abnormal sound and other ways to judge. In some cases, the hard drive cannot be self-checked to the hard drive due to a partial burn in the circuit board. In some cases, the hard drive may appear after overclocking "hard disk read and write failure", many hard drives under high FSB will have some problems, light will not start, heavy data loss. Because the hard drive after overclocking the overall system upgrade is not very large, and very poor stability, so it is highly recommended to overclock the hard drive.
Whether it is hard disk hardware failure or software failure, in the absence of a certain technology to check, it may be very difficult. Sometimes self-operation on the hard disk generated two damage, the creation of data can not be recovered, it is not worth the candle, so when your hard disk failure, hard disk storage of important file data, it is recommended to consult Professional Data Recovery Center. We recommend the Day Shield Data Recovery Center , whether in the hard disk Open data recovery or server array recovery, are in the leading domestic level, through strong technical equipment support, with independent research and development of professional data recovery software, day Shield Data Recovery Center engineers will help offsite users to detect hard disk failure , and provide the appropriate data recovery services. This is a free service designed to help users understand how to protect their hard drive from data loss and provide them with the appropriate problem resolution strategy.
