Sometimes our PC fails or just refuses to recognize the External Hard Drive even after confirming the successful connection. The problem occurs mostly when the device driver is either corrupted or outdated. Such problems can be quite tricky to fix. You can spend hours but find no solution. Try these workarounds and see if the problem of the External Hard Drive not being detected in Windows is resolved.
External hard drive not showing up
Before you begin unplug the external hard drive from the port and insert it into another port. If it works, maybe your first post is dead. Alternatively, use another USB and check. If it works fine in both ports, perhaps your USB is dead.
Run the Troubleshooters
The first thing you want to do is run the Hardware and Device Troubleshooter and the Windows USB Troubleshooter and check if it helps. The automated tools check the hardware/USB connected to the computer for any known issues and fix them automatically.
You could search for them via your Start Search, or you can access these Troubleshooters via the Windows 10 Settings Troubleshooter page.
Update or Reinstall the device driver
To do this, go to Device Manager by pressing Win+R together to open the “Run” dialog, enter devmgmt.msc. Next, locate the external device from the list. If you see a yellow/red sign appearing against the driver, right-click on its name and select “Update Driver Software…”. Also if you find any “Unknown device”, update it too. Select “Search automatically for updated driver software” and then follow the instruction to finish the process.
If this does not work, uninstall and then reinstall the driver.

Create new partition on your removable drive
If you never connected your hard drive to your PC earlier and are trying to connect it for the first time, then, the drive may not be detected since you do not have any partitions created for it. However, the same may be recognized by Windows Disk Management tool. So, verify if Disk Management tool can locate the external hard drive.
Open Disk Management tool, go to Search, type diskmgmt.msc and press Enter. If the external drive is found listed in the Disk Management window, simply format it properly, so that it shows up next time you connect it to your PC.
If you see that the drive is unpartitioned or unallocated, the format and then create a new partition there and see.
