About two years ago the internal hard drive crashed (did not know there was an additional internal drive) and the computer store in our community, which does 90% repairs and support, did replace the drive. Is this suspect? Probably, although they have a great reputation in our adult golf and retirement community of 5,000 homes. I did notice the black double faced tape was "tacky" feeling but also did not know the front was only held on by adhesive tape because I saw, what I thought were metal clips across the top. Not sure what they are for but honestly, was more interested in having it replaced as soon as possible. I received a call late today and it is ready to pick up. I've seen many things "happen" in my 82 years and blame no one and this is the case here. I appreciate the responses from the Forum as after having Macs for over 25 years have never been there. My wife was an IBM employee and therefore did not use Macs until I went to the Kodak Center for Creativity in 1991and was introduced to Photoshop One and the change became a necessity.
