My Macbook Pro (specs here): has been having issues keeping a hard drive connected and was having same issues this morning when I noticed my menu bar was almost completely WHITE. I tried restarting the computer and it got down to the spinning circle where it just hung there. I forced it to quit by holding down the power button, gave it a couple minutes and then powered it back up. Upon powering it back up my preferences are kind of off. For instance, My trackpad action is the opposite of how I had it set, Safari opens to yahoo.com instead of the pages that were open on my last session, and I'm guessing there's other preferences that are off that I just haven't uncovered yet. Any idea what's going on?
