You adjust permissions for cdroms and Windows drives by editing the /etc/fstab file. In the fstab, look for the lines that refer to the devices you want to edit. Then adjust:
#example:
/dev/hdc /mnt/cdrom iso9660 defaults,owner,ro 0 0
/dev/hda1 /mnt/win vfat defaults 0 0
Change above to (by adding, removing certain things):
/dev/hdc /mnt/cdrom iso9660 defaults,
users,ro 0 0
/dev/hda1 /mnt/win vfat defaults,
umask=0 0 0
Edit: 'users' lets reg users mount the cdrom, 'umask=0' sets permissions on windrive to rwxrwxrwx.
