You can.  As Adrian says you should be able to use a
ClientRunBeforeJob directive.  This will tell the client to run a
script which should be a shell script that checks for the presence of
a drive.  If it does not detect the drive, exit with exit code 1 and
the job will not run.  If it does detect the drive, exit with exit
code 0 and the backup job will run.  I missed the previous portion of
this thread, but I'm assuming this is a Linux client that is mounting
a drive.  If that's the case, then you're still functionally getting
an incremental but because the directory was empty last time (when the
drive was not mounted) but now has the entire drive's contents in it.
The incremental job is dutifully backing up all changed data from the
last incremental which happens to be all of the data on the drive now
that Bacula can see it.  Merely detecting the drive with a
ClientRunBeforeJob script will solve that problem entirely.

If you have many drives you interchange in this way, I would recommend
making your script take an argument so you only have to maintain a
single script that can check any drive you want as dictated by the
job.

If you do this I don't see why you would need 2 filesets and 2 jobs.
It should work just fine with one of each unless that is addressing
something I missed from previous emails.
