wurm, try booting with your backup drive to see if it has the same problem

Classical symptom of a bad hard drive.
I expect SMART Utility will indicate a failing drive.
I doubt it will. If wurm had made a chart of the number of bad sectors over the last year, my guess is it would have been steadily going up and is now going up faster. My experience is that SMART Utility gives the best info when you pay attention to it and will usually only give a clear warning in a period of about 72 hours before it completely fails.
I am not sure if you agree or disagree with me here, because my guess is that the disk has bad sectors, and SMART Utility will indicate as "Failing".
I have seen exactly this effect on a super slow MBP, lots of failing sectors and sometimes reading errors. I put in an SSD and new OS and it is zippy now. Will return it today to my friend.
