I have bought a new Western Digital External Hard drive and it used to work fine in my Vista system. Usually, when ever i connected this hard drive to my computer, then after a couple of minutes of its driver installation, vista would recognize the drive and i would be able to browse all and my files and can even play them. But since yesterday, after plugging this hard drive, it is not showing up in the computer. But there is still the safely remove hardware icon visible. Even in device manager the hard drive is working fine, as it says. I am totally blanked here, if the hard drive is working then why it is not showing in my computer, can anyone help.
