What if the computer can't find the hard drive?

Hard disk in the hearts of every computer user, hard disk occupies a very important position, because we almost all the usual use of a large number of important data is stored in the hard drive, once the hard drive has a problem, then the loss is big.

But for each hardware device, in the application process will always appear in such or such an unexpected situation, the hard drive is no exception, but if the hard disk has occurred, then how can we avoid enough to solve it? Let's take a look at some of the following solutions or experience.

　　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.
