I just traded a friend for this Xbox, it wasnt reading discs and even opening and closing the tray didnt always work. it has the Hitachi GDR-3120L drive and supposedly they had replaced it. when you would put in a disc it would try to spin up and would show as reading on the screen. then it would make a terrible screaching noise. I have never had a 360 before or worked on one. but have hacked/modded alot of other things. so i took it apart to see if they had messed it up somehow. long story short. now the drive wont do anything, the laser wont realign, the tray wont even try to eject and i just dont have any idea whats going on. thoughts ideas? I was thinking of getting http://www.thegamersfix.com/product.php?productid=16164 but if the drive doesnt respond at all what are the chances that the board is bricked? what are my options?
