You need to make sure you're trying to mount the block device /dev/wd0s1a (or whatever partition you're trying to boot) in /etc/fstab. /dev/rwd0 is the raw disk device; the first few blocks ara your boot blocks and are certainly not a filesystem :) If this doesn't make sense, post your /etc/fstab and we'll make sure it's correct. I assume this error from fsck comes up on bootup.
