I think my hard drive in my Macbook is dying a slow death. When I get home I am going to verify that Time Machine has a good backup and do some extra backups on DVD before calling Apple.
Update: Yep, it is the hard drive. The Apple tech support guy didn’t even question me, he just started the process to get it repaired. Also going to get the trackpad button on my Macbook fixed…it has been sticking recently. Time to do some mega backing up.
