Thanks, this worked out fine.  I used the disk from one of the defect
servers on another machines E-SATA connector:

# mount /dev/sdc3 /mnt
# chown -R mfs.mfs /mnt/*
# echo /mnt >> /etc/mfshdd.cfg
# /etc/init.d/mfs-chunkserver restart; tail -f /var/log/daemon.log

This dropped my missing chunks count from ~10000 to 1783. After one
night no chunks were under goal; so I can now proceed with the next
disk.

After some failed attempts to mark the disk for removal by prepending * in
/etc/mfshdd.cfg this worked also.

Thank for your Help!
