[newbie] Disk problems

[Strike, Jeff]

My system locked up and couldn't get any sort of response from it so I ended
up hitting the <shudder> reset button.  Now when it boots up I get a message
saying: /dev/hda1 unexpected inconsistency.  Run fsck manually.  I have to
enter the root password and it puts me at a prompt.  I run fsck and it just
says Parallelizing fsck version 1.14 and does nothing.  fsck --help does the
same thing,  I type man fsck and it tells me command not found.  What do I
do from here?
