Have you checked Disk Management?

It’s normal for the drive to come on when connected to the USB port

Thanks for you help, but i think you did not get my issue.

The hard drive is not been recognized by 3 3 different computers that i checked, also not recognized by WDTV live device.

The light staid bliniking even after i am disconnecting the USB cable, and only the power cable is connected.

Thanks

Put your ear to the drive when it is powered on and connected with USB cable. Do you hear anything? Spinning, buzzing, ticking, silent?
