If you just moved the drives, and did not edit the /etc/fstab
then just boot to single user mode, and edit the /etc/fstab.
Remember that when you boot to single user mode, you will not 
have the partitions mounted, do a mount -a -t ufs to get the 
/ partition to read/write, and then you can mount the other 
partitions as neccessay, I would recommend mounting /usr and
/var so that vi will work, or you can use ed to edit the /etc/fstab.
