my hard drive to the WD Scorpio Blue 750GB one and I'm about to cry I just paid back my mom the other day for this 13" $999.99 laptop I got at Microcenter and I knew this was going to happen one day but I didn't want this to happen right now. Whoever assembled my laptop screwed in the screws really tightly and I had the right screwdriver and while I was unscrewing the two middle tiny screws, my screwdriver slipped and now there's an 1/2 inch black scratch near one of them. I also scratched the aluminum near another screw but you can barely see it (a clear scratch I guess but you can feel the indent) How do I buff the black line away? Is there a special silver aluminum paint I can buy or some type of polish? Thank you!!!!!
