My WD Essential External Hard Disk is not getting detected on any machine. On connecting to the laptop / desktop, the light on the Hard Disk glows but the hard drive doesnt get detected.
If the drive is not seen when you connect it to your computer then you should try some basic troubleshooting:
1- Connecting the power adapter to the wall directly.
2- If the computer is a desktop, connect it on the back USB port (directly to the PC, not through a hub).
3- Make sure you hear the connection sound windows makes when recognizes a USB device.
4- Go to "Disk Management” to verify if the drive shows up there.
If the drive shows up in disk management but it is not seen on Computer, then it means the partition is corrupted and you will have to format it in order to use it again. Please note that formatting the drive will delete all data stored on it.
