Answer:
Step-by-step explanation:
The first thing that you would need to do is verify that the drives are being detected within the BIOS. You need to first enter the BIOS by clicking the correct keyboard key on startup. If the BIOS detects the drives correctly, then the most likely problem is that the drive's letter is not assigned. To fix this you need to search for Disk Management within the OS, find the drive, and assign a letter to it. If this does not solve the issue then the cable or drive itself may be damaged and may need replacing.
