My one Tb Transcend hard drive just stopped working. When I plugged it on my PC, it vibrate and the light indicator shows up but not recognized on the PC. It's also not in the list when I used the disk list on CMD console. I also tried disk management console and it's not part of the list.
It could be related to a driver issue. Open Device Manager, find and right-click on your hard drive's driver, then choose Update driver.
If you can't find the driver, or if the problem persists, go to View > Show hidden devices. If you see grayed-out drivers that are related to that hard drive, right-click on them, choose Uninstall and restart your PC.
