This can happen sometimes when machine crashes.  However, I would still 
recheck log files to see if there were any warrnings/errors on /dev/sdb 
(these are usually the very first signs that disk might fail soon).  
Keep an eye on that drive, and recheck logs (/var/log/messages) from 
time to time.  If you see any errors reported on it, replace it 
immediattely.
