Thread: Hard drive not shown in BIOS

I have Compaq PC and it supports SATA hard disk. I am attempting to attach new SATA hard drive to it. But problem is hard drive is not detected by my PC. So please help me to solve this problem.

I think hard disk is not attached to system appropriately. So attempt again by reattaching it appropriately on motherboard.

If new SATA hard drive is not shown in BIOS after reattaching it to structure then problem is with SATA cable which used for linking hard drive on motherboard. So try to connect this hard drive on other system with similar SATA cable. Then you will recognize problem.

If this hard drive is shown by other desktop PC by similar SATA cable then problem with port of motherboard. If other ports available then attempt connecting it to them. This may solve the problem.
