Hey guys, about a month ago I received an email letting me know that my iMac was part of that growing number of machines affected by failing Seagate HDD's. I really haven't had any time to make an appointment at my local Apple store but I think I may do it in December. Has anyone gotten theirs replaced by apple, and if so what did they do with the old hard drive? Do they erase the data, how to keep all that info from falling into the wrong hands? Thank you.
