Here's a snippet from a bash script I use to do the same thing with
a dvd burner. The burner is external, so the script has alread checked
to see if the burner is mounted.
melding=$(sudo mount -t ufs -o rw /dev/cd0a $montering_punkt 2>&1)
#Om mount ikke returnerer 0, er noe galt.
if [ $? -ne 0 ]
then
if [ "$melding" = "mount: /dev/cd0a: Device not configured" ]
then
HTH,
