Hard Disk can't read in "my computer ", "initialized",I/O device error

I have a big problem here,
I have used my hard disk for 9month,
Yesterday when I watched movie on the half way,
My hard disk suddenly disfuntion,
And I thought my laptop problem due to always lagging so I restart my computer.
But after that I can't read my hard disk (WD)in my computer.
It can read in computer management there.

Ways I try:
1)I try to uninstall and reinstalled again,BUT it doesn't work.
2)I try to unchecked the hide folder and device at view.
3)I try to update the software BUT it still disfunction.
4)I try to use disk management and initialized it BUT there appeared CANNOT INITIALIZED Due to I/O device error.

Any solution for me ?

The most usual cause is that the Hard Drive is beginning to fail. Back up your stuff. Go to the website of the manufacturer and test the drive.

Hopefully u haven't sent it yet, because 99% you will NOT get back any of your old data (in case you needed it :))
