[CentOS] Raid issue

I am curious about something.  I have a friend that made a software raid 
1 partition across a 250 gig 7200 rpm drive and an 80 gig 7200 rpm hard 
disk drive.  he shut the system down normally to clean it out and when 
it came back up he gets the following:
a superblock on /dev/md0 failed

would mdadm --assemble --force fix it or lead to more damage?

My "Foundation" verse:
Isa 54:17  No weapon that is formed against thee shall prosper; and 
every tongue that shall rise against thee in judgment thou shalt 
condemn. This is the heritage of the servants of the LORD, and their 
righteousness is of me, saith the LORD.
