Urgent Help Filesystem corrupted (automatic fsck failed)

[OOzy Pal]

Hello,

Suddenly my file system says I have a read-only filesystem.
I restarted the computer. I then got

checking root file system....
/contains a file system with errors check forced (something like that)

Then I got so many of
/:Multiply-claimed block(s) in inode xxxxxxxx: xxxxxxxx

after that I got fsck auto failed (or something like that).

Then I get taken to the command line to do manual fsck.

Ahhh, what should I do?
