Wd external hd is not working

my external hard drive is not showing up on my pc and the light is flashing.how can i get it to work so thatbi can see the data on it.

Hello,

Please try the following troubleshooting steps:

1- Connect 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.

I have the same problem now it only comes up asking to initializ disk when I do it comes up i/o device error is there a way to fix that
