With tomorrow's Black Friday's sale i'm looking to either purchase a small portable external hard drive or better yet, a hard drive for my white macbook to replace my current one that only has 60GB's of space, 10GB's currently. I know replacing it is simple but haven't the slightest clue as to what to look for when I purchase a new one. I'm assuming perhaps a specific make/model or number or something? Any help is truly appreciated. BTW, Happy Thanksgiving!
