Can you try the following patch: OK, on a different system that has similar false CD detection and with the patch and with CAMDEBUG and `camcontrol debug -c all`: # camcontrol cmd cd0 -v -c "25 0 0 0 0 0 0 0 0 0" -i 8 "i4 i4" -791621424 -791621424=20 # tail /var/log/messages (xpt0:xpt0:0:-1:-1): debugging flags now 8 (pass0:ata1:0:0:0): READ CD RECORDED CAPACITY.
