OK. You need to follow the steps in http://www.freebsd.org/doc/ 
en_US.ISO8859-1/books/handbook/raid.html section 18.4.3. Be careful  
to detach/reattach the right disk :-)

When the rebuild has finished you may find that the BIOS doesn't  
realize the array has been rebuilt, but that may not matter (much).
