/dev/hda1: UNEXPECTED INCONSISTENCY: RUN fsck MANUALLY.

[Jay Kelly]

Hello Group,
I am having a problem getting my Potato box to boot. I just installed a Half
Life Game server and it has been working great all day. I tried to read my
mail and after typing mutt I get an error: can't create a temporary
filenames. So then I did a reboot and when it comes to checking /dev/hda1 I
get another error:
/dev/hda1: UNEXPECTED INCONSISTENCY: RUN fsck MANUALLY.
so how do I fix this? Was this coaused by Hale Life I installed? And how do
I run fsck?
Thanks guys
