corrupted drive - red hat won't book
I have an old box running Red Hat 5. I had a misfortune of losing power when the system was running and now it won't boot. It gives me an error message stating that there's a fault on one of the drives, tells me that it has to check that drive, and then it lets me login as a root but will not let me do anything (for instance the networking option does not work). But I did notice that it told me that I should use the 'fsck'. But I'm very much unfamiliar with that. Any idea of what I can do? Thanks for any suggestions?
