[arch-general] Can't mount a certain type of ISO CDs
Hi, I can't mount a whole bunch of CDs/DVDs I've burned back in the days I was using Mac OS X. They've been burnt with the 'Hybrid Mac/PC' scheme of the following program: http://burn-osx.sourceforge.net/Pages/English/home.html isoinfo -d dev=/dev/sr0 Gives the following output: CD-ROM is in ISO 9660 format System id: APPLE COMPUTER, INC., TYPE: 0002 Volume id: MY_CD Volume set id: NOT_SET Publisher id: Data preparer id: Application id: TOAST ISO 9660 BUILDER COPYRIGHT (C) 1997-2005 SONIC SOLUTIONS - HAVE A NICE DAY Copyright File id: Abstract File id: Bibliographic File id: Volume set size is: 1 Volume set sequence number is: 1 Logical block size is: 2048 Volume size is: 2275987 Joliet with UCS level 1 found NO Rock Ridge present Unfortunately, mount -t iso9660 /dev/sr0 /mnt/dvd responds: 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 and generates the followings dmesg entries: attempt to access beyond end of device sr0: rw=0, want=68, limit=4 isofs_fill_super: bread failed, dev=sr0, iso_blknum=16, block=16 Regards, -- Bastien

mount -t iso9660 /dev/sr0 /mnt/dvd
Try without the -t part.

I already tried. If I do so, mount asks me to specify the filesystem.
I guess it won't return anything, but please try blkid /dev/sr0 or blkid -p /dev/sr0

Tried both: nothing's returned. Cheers, -- Bastien

This can only mean two things: 1) You get read errors (see dmesg) 2) The file system on the discs is not recognized by util-linux (and thus probably not by linux either)

It has to do with the drive, because I tried to mount the same CDs with an external DVD drive and it worked. Regards, -- Bastien

Hi,

They've been burnt with the 'Hybrid Mac/PC' scheme of the following program:
http://burn-osx.sourceforge.net/Pages/English/home.html
isoinfo -d dev=/dev/sr0
Gives the following output:
CD-ROM is in ISO 9660 format System id: APPLE COMPUTER, INC., TYPE: 0002 Volume id: MY_CD Volume set id: NOT_SET Publisher id: Data preparer id: Application id: TOAST ISO 9660 BUILDER COPYRIGHT (C) 1997-2005 SONIC SOLUTIONS - HAVE A NICE DAY Copyright File id: Abstract File id: Bibliographic File id: Volume set size is: 1 Volume set sequence number is: 1 Logical block size is: 2048 Volume size is: 2275987 Joliet with UCS level 1 found NO Rock Ridge present
Unfortunately,
mount -t iso9660 /dev/sr0 /mnt/dvd
responds:
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
and generates the followings dmesg entries:

Given the fact it's from OS X I guess it can be HFS or HFS+ file system. Try: mount -t hfs /dev/sr0 /mnt/dvd or mount -t hfsplus /dev/sr0 /mnt/dvd Lukas
