I wish I knew. I do know when the drive got wrecked, it was after sitting in my carry on after a 16 hour plane ride overseas. I don't even take it out anymore I'm so scared about the fragility of it. I have to say this, overall it looks better after a year of hard use than most of my Dells. My other notebooks look terrible too, but I attribute that to cheap plastic. Little pieces broken off on the corners, battery that won't stay in place, etc. I use computers hard if you can't tell.
