My wife (that's my story, and I'm stickin' tuit) accidently plugged her Toshiba laptop power supply, 19v, into her WD external hd, 12v. The power light on the drive started flashing off and on. Now, with the correct power supply, it is still flashing. It won't turn off, or on, and the computer cannot see it. The drive was working fine last night. Did the 19v kill it, or any ideas? I can't find any kind of reset button on the drive.
