If the controller chip on that HD fried, then you would have to send the drive off to a professional recovery site that has the hardware/software necessary to do that kind of recovery and it is a huge expense. If your system does not recognize the drive at all in the bios...the controller chip is fried and your in bad shape. Immediately go and buy another HD for back up. They are so inexpensive today tha it makes no sense to run a single drive expressly for the reasons you are now facing!!!
