Possible to exclude a drive from event processing at startup?

Question

I clone my iMovie drive regularly as part of my backup plan.  As a result whenever I open iMovie it sees the same events on both disks and takes lots of time processing them(there's a good 1.5TB to look through).  Is there a way to have this initial scan ignore the backup?

Here is my current version of the shell script.
#!/bin/sh
#disktool -e disk0s9
for ((i=0;i<4;i++))
diskutil unmount /Volumes/classic | grep "Volume /Volumes/classic unmounted"
rc=$?
echo "rc="$rc
if [ $rc -eq 0 ]
then
echo "unmounted i="$i
break
fi
echo "i="$i
sleep 8
}
