the drive going bad might not have had anything to do with "your friend" dropping it on concrete would it? =p
regardless, I definately have to say kudos to Nintendo for their customer service and support behind their system. I myself had a drive that had gotten louder and louder and was buzzin like mad, BUT everything worked just fine. (bought in Jan. 07, sent back in Feb. 08)
They sent me a shipping label and I sent it out and got it back good as new IN UNDER A WEEK, and no cost to myself. Not only that, but when they do a repair...they auto extend your warrantee for an additonal year from repair date (regardless of purchase date).
pretty slick indeed =)
