So, I'm back sitting at the problem ... I installed the libcdio-utils and cd-info told me: CD Analysis Report CD-ROM with both Macintosh HFS and ISO 9660 filesystem ISO 9660: 277064 blocks, label `MINDSTORMSNXT' Application: Preparer : Publisher : System : APPLE COMPUTER, INC., TYPE: 0002 Volume : MINDSTORMSNXT But dmesg reported: hfs: can't find a HFS filesystem on dev hda. ISO 9660 Extensions: Microsoft Joliet Level 1 ISO 9660 Extensions: IEEE_P1282 After puzzling around a little bit, I mounted the cdrom with hfsplus: /dev/hda /media/cdrom1 hfsplus,iso9660 uid=1000,ro,user,noauto 0 0 and finally it worked :-D Thanks for your support.
