PE can not identify the hard drive what's going on

　PE can not identify the hard drive reason:

Generally speaking, the PE can not identify the hard disk mainly has 3 kinds of reasons:

1, hard disk mode settings are not correct

Hard disk Mode settings are more common, the general hard disk has AHCI and IDE common two modes, for some of the older PE tools, only support IDE mode, the user needs in the BIOS settings, the hard disk mode to the IDE, in addition to Win7 above the system or solid-state drives, Typically, you need to open AHCI mode, so if you are unable to recognize the hard drive under PE, you can switch the mode.

　2, hard disk failure (including improper installation of hard disk, hard disk itself hardware failure);

Hard disk failure is mainly the hard drive is not connected or the hard drive is bad, for this situation you can see whether the BIOS to recognize the hard drive, if the BIOS can not recognize the hard drive, the basic description of the hard drive is not installed or the hard disk itself has problems.

3, PE tool version is too low

In addition, some may be the problem of PE tools, such as the PE tool version is too low, the low version of the PE tool, the general need to switch the hard disk to IDE mode to recognize.

　PE does not recognize hard drive solutions

After understanding the approximate 3 kinds of reasons, it is better to solve, if the BIOS does not recognize the hard drive, then the hard disk installation or the problem itself, and the PE tool can not, need to check the hard drive installation and whether it is bad.

If the PE version is too high or low, you can identify it by switching the hard drive mode.
