EXT3-fs error

[Louis Hopcraft <lhopcraft telus net>]

Hello all.

I'm using RedHat 7.2 now and haven't have any problems until today.  I
can still boot into the system at this time, but cannot load X at all. 
I'm getting the following error message when I try to run fsck.

/contains a file system with errors, check forced.
Pass 1: Checking inodes, blocks and sizes
Error reading block 1277964 (Attempt to read block from filesystem
resulted in a short read) while doing inode scan.  Ignore error<y>?

No matter what I do (Y or N) the results are the same.  The problem will
not go away.  Does anyone have any ideas as to a fix, or to what the
problem is?  When I do a fsck and it marks the fs as clean I reboot and
login the system.  But I still cannot load xwindows.

below is some output from dmesg:
