My WD external hard was dropped. It worked for a little while but it had power issues (would not turn on) so I had to jiggle the power cord to turn it on. It does not work now. I removed the drive and connected it to my PC using the Apricorn universal hard drive adapter. My PC does not recognize it. It shows up in the device manager but states it is not initialized and disk is unlnown. How can I recover the data on the drive?
