hard disk failure or???? URGENT

After a reboot I got following message after the console login: clm-6005: writing mode 737 on readonly FS My normal graphical login was absent and there is no login possibility after this message. Neither as root nor as user. Before I go into my SuSE 8.2 with the rescue mode I would like to know what I should do and where I should start repairing. Any ideas. Need more info?
