You can only run fsck(8) on partitions containing filesystems. The
'b' partition is usually a swap area, which doesn't use any sort of
filesystem at all. The 'c' partition usually maps to the whole slice
-- that is, it overlaps all of the actual partitions you're using for
your file systems. You very rarely need to access the 'c' partition
specifically -- commands that affect the whole slice nowadays tend to
take ad4s1 or the equivalent as an argument.
Your /var and /usr partitions probably live on partitions 'e' and 'f'
-- possibly 'g' or 'h' as well if you have any other
partitions. disklabel(8) will show you what partitions have been
