I just had the misfortune of having my poor hard working notebook die on me.
My gut feel is that it is the notebook motherboard. I am hoping and praying that this is the case as there is some stuff on the notebook hard disk that I really want to get back.
It turns out that there is hope. Since I was already looking at replacing the notebook, if I can get the hard disk data off, then I won't be so unhappy.
My hope is that when I get a notebook adapter cable, I will regain access to my notebook hard disk via my desktop PC. These handle little adapters can convert a 2.5" (Notebook) Hard Disk Drive into a 3.5" Compatible IDE Hard Disk Drive.
