Unrecognized HDD is a common type of HDD failure. The following is a brief description of how to repair the HDD can not be read out, everyone who is interested can come to understand!


First, the HDD partition problem caused


When using a computer hard drive, you must first set up partitions, and there are divisions between the main partition and the logical partition. In the case of a failure of the main partition, computer failure will occur. You need to enter the DOS mode by booting to enter the FDISK/MBR command to set up, so that the problem can be solved, because the FDISK command file already contains an HDD main leadership program, and some modifications can solve this problem.

Second, due to improper BIOS settings


When setting the HDD working mode on the Bios motherboard, there are three situations, including Normal, LBA and Large. The installation needs to be set according to the situation of the HDD, otherwise, it will be prone to some failures or problems. The correct settings must be made in accordance with the motherboard's BIOS manual and the HDD itself, so as to solve the phenomenon that the computer does not recognize the HDD.

3. The system cannot find the HDD or cannot recognize the HDD after booting


If the computer does not recognize the HDD after booting, it may be whether the compatibility of the HDD has failed, but there are no problems with the HDD and compatibility, so it can be ruled out. This failure is usually due to a problem between the HDD and the motherboard. If such a problem occurs, you can replace a connection cable between the motherboard and the HDD. If this failure cannot be eliminated, you can check whether the master and slave cables are set correctly.
