Repair Hard Disk Not Detected Error

Try the following steps to try and isolate/troubleshoot the problem.

Method 1: Drive not enabled in the BIOS

System Setup is also called the "system BIOS" or sometimes the "CMOS Setup". Different computer manufactures have different methods to enter Setup, so please check your system documentation for specifics. For example, on Dell computer you will see "F2=Setup" in the upper right hand corner during the computer boot-up, This means to press the F2 key to enter Setup (the BIOS). Then you should add a second drive to the system, it may be need to be enabled by turning it ON in System Setup.

Method 2: The Serial ATA motherboard drivers are not properly loaded.

When you install older versions of Windows on a drive that will be the boot drive (ie, the C: drive), when it comes time to install Windows, the drive may not be detected. You might need to update the driver for your computer storage controller.

Method 3: Faulty or Unplugged Data Cable

The BIOS will not detect a hard disk if the data cable is damaged or the connection is incorrect. Always inspect the motherboard and hard disk connections for bent or misaligned pins. Folding, crimping, pinching, or creasing data cables can cause the wires to break inside the insulation. When in doubt of data cable condition, replace it.

Method 4: Drive is not spinning up

If the drive is not receiving power or receiving an incorrect level of power, it will not spin up.
If you cannot determine whether the drive is spinning:
       1.  Reboot the computer and listen carefully.
       2.  Disconnect the power cord from the computer itself.
       3.  Disconnect the power cable from the questioned hard drive.
       4.  Reconnect the power cord to the computer itself. Boot the computer up to see if the drive sound was audible before.
       5.  Check the power supply on your computer to determine whether it is providing sufficient electrical power to operate the drives and devices you have in your computer.
       6.  If the drive is still not spinning, connect it in another computer if possible.
