I took the hard drive (a barracuda 7200.7 30 gig by seagate) out of my dell Pc when I got this laptop for Christamas(wife). I was told that I could take the hard drive out put it in an external hard drive case. I did so, however, it recognizes it as Mass storage device/ then it says the new hardware is installed and ready to use/ then it says there was a problem during install and the hardware my not work. I have been through MS Support /Seagate/ support/ Gateway support. Please I have so much data on the drive it is extremely important. Any help would be incredible!!!!!!!
