Sorry to bump this thread. Using the instructions provided under Ubuntu 12.04 LTS, I get the following errors when mounting the Mac OS X install disk for Snow Leopard:
# sudo mount -t hfsplus /dev/cdrom /cdrom
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
dmesg | tail gives me:
[382843.817892] hfs: unable to find HFS+ superblock
[382851.522141] hfs: can't find a HFS filesystem on dev sr0.
[382864.374908] hfs: unable to find HFS+ superblock
[382870.247657] ISO 9660 Extensions: Microsoft Joliet Level 1
[382870.248071] ISO 9660 Extensions: IEEE_P1282
[383006.369544] hfs: unable to find HFS+ superblock
[398360.434317] hfs: unable to find HFS+ superblock
Mounting the same disk under ISO 9660 works flawlessly, but I get only the partition that is usually reserved for a Windows BootCamp install.
My reasoning is that the Mac OS X Install Disk is a hybrid DVD-ROM which requires some special extra setup for Ubuntu to recognise it as such — Macs are able to do that natively, but Ubuntu might require something else, perhaps using a different block device?
Any clue to what I should be doing?
