Please refer to Case 4 and use MiniTool Power Data Recovery (Damaged Partition Recovery) to help you recover data. Then use MiniTool Partition Wizard Free Edition to do the formatting.
Case 6. Drive not enabled in the BIOS
If hard drive is not showing up in Disk Management and Device Manager, it may be because it is not enabled in System Setup (BIOS). Some motherboard manufacturers disable unused ports in the BIOS by default, which is the common reason for the 2nd hard drive not showing up in Windows 10/8/7. You will need to enter BIOS to verify their current states and make sure all hard drives are enabled. Note that different computer manufacturers have different methods to enter system BIOS, please check your system documentation for specifics.
Case 7. Faulty cable or port
If the data cable is damaged or the connection is incorrect, the BIOS will not detect the SATA cables and can sometimes fall out of their connection. Be sure to check your SATA cables are tightly connected to the SATA port connection. The easiest way to test a cable is to replace it with another cable. If the problem persists, then the cable is not the cause of the problem.
Case 8. Troubleshoot drivers
Usually, Windows offers hard drive drivers and the manufacturer of your SSD may also have released some drivers to support your disk. However, it is possible that they are the causes of your hard drive not showing up problem. If the driver you use is outdated or problematic, you need to disable or uninstall it. If you are not familiar with the process, use professional driver tool to help you get rid of the worries.
Case 9. Virus attack
Some malware or viruses can lead to hard drive not showing up issue. It is possible that there are such malware or viruses on your computer. In this case, please run security software on your computer to scan out and remove these malicious programs. Then, check if Windows doesn't recognize external hard drive issue still persists.
Case 10. Faulty hard drive
If you have completed the above checks and the external hard drive is still not showing on your computer, you should send the hard drive to repair center and check whether it fails. If it is still in the warranty, please proceed to begin a warranty replacement.
