The "bad superblock" message indicates that the superblock is corrupt. Typicall this will happen only in the case that something is writing that area of your disk. My first suspect would be the MSDOS FS. Are you mounting your DOS partition read/write? Don't. Other possibilities include: placement of the BSD partition on disk is inconsistent with the partition table and/or disklabel data. Are you sure you told the install the geoemetry that your IDE drive uses?
