I had the exact error 9 months or so ago (look for a similarly titled  
thread in the archives).  It was a disk going bad.  Get all the data  
off you need now and replace the disk ASAP.  It may run for a few  
days/weeks before it gets mounted again read only, but eventually you  
will lose some data.
