That probably means that your are targetting the wrong partition/slice
of your BSD partition.

I can't guess your setup but you have probably a primary partition
on the slave IDE drive and some BSD slices inside (a/b/c/...)
hdb1 is the whole partition and probably not your BSD slice you
want to mount... Depending on the other primary/extended partitions
on hdb, you might need to try hdb{2...15}.

-> sfdisk -d /dev/hdb
-> fdisk -l /dev/hdb
-> grep hdb /var/log/messages
