computer does not read hard drive how to solve

Computer does not read the hard drive the reason and the solution one:

The hard drive is not detected by the computer.

1, in fact, can not detect the hard disk is not only the motherboard or hard drive reasons. Describes how to detect the elimination of this type of failure and the computer can not detect the hard disk mode:

2, first of all, to detect the hard disk line problem, because the hard disk line problem is very common, and easy to exclude, manual operation simple and fast. Try a new hard drive line. If the hard drive is detected, the problem is resolved. If it is not detected, continue.

3, second, to change the hard drive back up, try to find. The operation is relatively simple, if found to detect the hard drive, then complete. If it is not detected, continue.

4, and then talk about special circumstances. If the optical drive and hard drive are the same port, then you can detect the jumper, first the optical drive does not see whether the hard disk can be detected, if detected, the problem is the jumper. The solution is to repeatedly replace the hard drive jumper and the optical drive jumper until all can be found.

5. There is also a special situation, for the motherboard has done diskless system, in the CMOS settings changed, need to be based on each brand of the motherboard to adjust, but will not adjust also does not matter, tell a very simple way: the motherboard battery to take off a while up will be able to restore the default settings. In the default settings, the motherboard will not be able to block out the hard drive.

Secondly:

If the physical hard drive is broken, it will be difficult. You can find a professional repair person or company.

If it is a minor damage, you can try to insert a win PE CD, run the Win PE system, enter the D disk data read out.

A computer hard disk is the most important storage device for a computer. HDD (RTHK called hard disk, English name: Hard disk Drive short HDD full name Winchest) consists of one or more aluminum or glass discs. These discs are covered with ferromagnetic materials. Most hard drives are fixed hard drives that are permanently sealed and fastened to the hard drive.

The early hard disk storage medium is replaceable, but today the typical hard drive is a fixed storage medium that is sealed on the hard drive (except for a filter hole to balance the air pressure). Along with the development, the removable hard disk also appeared, and more and more popular, the kind also more and more. The hard disk installed on most microcomputers.

Because of the use of Winchester (Winchester) technology is called "Winchester hard Drive", or "warm disk." The so-called Winchester disk is actually a technology, developed by IBM at the Institute of Campbell Winchester Avenue, California, which was first applied to IBM3340 Towers storage in 1973, and therefore called the Winchester Technology.

Computer does not read the hard drive reason and solution two:

The first type of failure is more common failure: The system did not find or can not identify the hard drive after the boot

The hard drive cannot be found after you start the computer by other means. In this case, the solution is still very simple, because so far, has not heard that the hard drive will appear and the motherboard compatibility issues, such failures are mainly in the hard disk and the connection between the motherboard, so here we recommend that you may wish to switch between the hard disk and the motherboard connection between a root, If it is not connected to the problem, then you look at the hard disk on the master-slave line is set correctly, how to set the status of the master and slave jumper will generally be on the hard disk on the tip, according to your own needs to set the hard disk as the main disk or from the disk can solve such problems

Second type of failure: improper BIOS settings can also cause hard drive problems

Today's motherboards are used to actively detect the type of hard drives and brand models, so we usually do not modify this, but because some motherboards in the runtime may identify the problem of the type of hard disk state, this situation will generally lead to the system can not boot from the hard disk. In addition, in the BIOS of the motherboard can also set the hard drive Normal, LBA and large, and other work mode, which must be based on the hard disk conditions to set up, otherwise it is likely that there will be other problems. This kind of situation is not difficult to solve, as long as the motherboard BIOS instructions and the hard disk itself, the correct settings can be resolved.

Third failure: A primary partition fails to start the hard drive

The hard drive has a primary partition in which the primary partition is started, and if the primary partition is faulty, then the system cannot be booted from the hard drive, which is a normal thing. It's not a very complicated thing to get this out of the way, as long as you enter the FDISK/MBR command in DOS mode, which is important because in the FDISK command file, it already contains the main leader of a hard drive, and now that Microsoft has thought about it, why not? From the current situation, the system can not properly lead the system of the situation there are many, but the common basis are mentioned in this article.

Fourth failure: The BIOS can identify, but the system is not recognized

This fault is when you add a new hard drive to your computer, in the BIOS can be seen, but the system in the Disk Management, Device Manager is not visible, in addition to the common jumper, set the master and slave disk, there is a little often overlooked, that is in the Device Manager, "IDE ATA/ATAPI Controller"-" Important IDE Channel "or" Secondary IDC channel "(You put the hard disk in the port to set that one) properties," Advanced Settings "--device 0--device type, if it is" none ", please change to" active detection ", and then restart it.
