Problem Booting (Bad Super Block)

I've started having problems on my FreeBSD box; I've installed FreeBSD
on this system at least 5 times before without any problems.
This time, the installation took many attempts, and the following error
message occurs when I attempt to boot up:
/dev/da0s1a: BAD SUPER BLOCK: VALUES IN SUPER BLOCK DISAGREE WITH
THOSE IN FIRST ALTERNATE
/dev/da0s1a: UNEXPECTED INCONSISTENCY: RUN fsck MANUALLY
Automatic file system check then fail, the boot process aborts, and the
system starts in single user mode.
How can I fix this error so that the machine boots normally? I am
unable to run fsck from the prompt by just typing 'fsck'....
