Hey guys. I'm changing my stock 320gb hard drive for a 500gb scorpio blue and everything was going fine till I got to the part where you have to take the four screws off the old hard drive... I used a T6 Torx screwdriver but the screws were as soft as a marshmallow and have totally threaded Plus they didn't move in the slightest when I turned. So now I don't really don't know what to do and I was wondering if you guys could help! Thanks.
