Since then, there is still clicking, but that particular hard drive is not showing up. Is that a sign that it's dead and the data is gone? Or is there a possibility that the data is still there, somewhere? Should I disconnect that hard drive in hopes of salvaging data?
For the record, Grandma told me she had been hearing the clicking sound for several weeks prior to all this happening. She didn't know what the sound was and didn't bother to tell anyone.
