Your old SCSI disk was da0.  Apparently your new IDE disk is ad1.  At 
the very least, you need to manually mount the / partition and edit the 
/etc/fstab file to reflect this.  A "live cd" like FreeSBIE 
(http://www/freesbie.org) may help you mount that partition and edit the 
file.

Your applications should all refer to files, not partitions.  So with 
the /etc/fstab file fixed, everything should work again.  You may have 
other hardware that will require changes to configuration files; a 
different network board, for example.

Incidentally, this same problem can occur even if you use the "proper" 
backup tools (dump/restore).  It's the contents of the fstab file, not 
the way you've transferred it.
