Your task is to diagnose and correct the problem. In the computer, the top hard drive contains the operating system files. Troubleshoot the hard drives to see why they are not all being recognized. Verify that all drives are detected in the BIOS.

Explanation:

The first thing that needs to be done is make sure that all of the cables are properly connected to each hard drive and that they are powering on when the computer is turned on. Next, enter the BIOS and check to make sure that all of the drives are being detected. If they are not then either the cables or the drive itself may be damaged. If all drives are detected then log into the operating system, on the search bar type and launch Disk Management. Here search for the drive that is not showing up and assign it a drive letter. It should now show up in the file explorer.
