Iomega Prestige 1TB Non-Responsive

My "friend" borrowed my Iomega Prestige 1TB while at my place recently, and while I was hunting for the 12v power pack, he decided to sick a 19v power pack in. Needless to say, the unit is not working; the only sign of life is the light on the side which now flashes in steady 1sec intervals. And of course, the unit is out of warranty. All I wan't is to get the data off the disk.

I know enough IT and Electronics to be talked through a solution. I've Googled the question with little to no prevail, albeit a glimmer of hope that if I ask for help, there should be an answer.

Please Help.
