 fsck -f fixes it, thanks. It seemed to be fixed by each reboot and still 
 kept coming back so I never tried to force fsck. I never had any error 
 message about it while booting or in /var/log/messages. Assuming "fsck 
 -f" fixes it definitely, when such problems occur, should a message be 
 output and the file system be marked "unclean" or something like that so 
 that a reboot would somehow force the user to "fsck -f" ? (sorry if if 
 seems stupid).
 
 Thanks again,
