You can refer to the following tutorial.

Step 1: Remove all external storage devices like USB drives, external hard drives, RAID, etc.

Step 2: Enter into BIOS or use the DiskPart command to check the number of hard drives connected to the PC.

Check the connection in BIOS:

Follow the wizard that appears on the screen when you power on the system to enter BIOS.
Skip to Boot Expand Hard Drive directory to see how many disks your PC can detect.

Check connection with DiskPart:

Open the Command Prompt window from WinRE and enter the following commands one by one. Then, you can see the number of hard drives detected by your PC.

Diskpart
List disk

list disk to see the number of hard drives detected by the PC

Step 3: Remove the internal hard drives and plug them in correctly if the hard drives can't be detected by your PC. If the hard drives still can't be detected by your PC after you reconnect them, you should check whether there are problems with cables or the hard drives.

If there is a problem with your hard drives, but they are still detected by your computer, you can get them repaired through method 6 to 7.Note: If the hard drive fails to be repaired, you can apply method 9 to recover data and replace the problematic disk.
