Get to know more about why hard drive is not being detected by BIOS


The hard drive stores data for the computers. The hard drives included in computers should be compatible with the motherboard since incompatibility results in various issues like hard drive not detected on BIOS, etc. BIOS can be viewed as the critical element upon the motherboard. So any issues with the motherboard would affect BIOS settings too. As a result the BIOS may not identify such devices. The difference in the hard drive type also causes not detected issues with the hard drive in BIOS. The wires and the cables that are improperly connected with the hard drive also cause issues with the hard drive and BIOS settings.


Discussed below are some ways to resolve the issue of hard drive not being detected by BIOS:




  • Check Connections of Hard Drive with Motherboard

  • Check BIOS Settings for Particular Hard Drive Type

  • Check Compatibility with Motherboard



Check Connections of Hard Drive with Motherboard



The physical connections of the hard drive with the system motherboard should be checked. The loose connections would cause 'not detected' issues with the drive. Firstly the user should check the power cable and the data cable that are connected with the hard drive are perfectly plugged in. The user should seek the help of the technicians before opening the system units for checking the wires and cables.



Check BIOS Settings for Particular Hard Drive Type



The hard drives are of various types. SATA drives do not require the jumper switches and will not be detected by BIOS by default. IDE drives require jumper switches and also require primary and secondary configuration settings. Such differences should be considered while configuring drives with the motherboard settings.



Check Compatibility with Motherboard


The motherboard included in the system should be compatible with the hard drive in the system. BIOS is an essential part of the motherboard and any issues with the motherboard would result in problems like the hard drive not detected. Thus the user should check the compatibility of the hard drive with the motherboard and should insert a new one if it shows incompatibility.
