growisofs -dvd-compat -Z /dev/hdc -R -J file1 file2 

And what is in your environment variables $1, $file1, $file2 ? 
If they don't get set before the growisofs call something weird is bound
to happen. Also are you sure you want to keep all access permissions
(-R)? That way you can't use the DVD onm other systems, but it *is*
useful for local backups. using "-r" would set read access for

Hmm.... again my manpage of mount suggest to put all options first and
*then* only the device and (existing)  mountpoint.

     mount [-fnrsvw] [-t vfstype] [-o options] device dir
