How to add HFS support for Mac CD & DVD

English Hardware
1

I am wanting to copy files from some old, Mac CDs, formatted HFS.

I have installed hfutils.

Attempting “sudo mount /dev/sr0 /mnt/cdrom” results in error:

mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error

I do not see any hfs formats listed in /proc/filesystems, which I suspect is where the problem lies.

How do I add hfs / hfsplus support to /proc/filesystems?

Hi
Install the hfsutils package, if you want a Tcl/Tk frontend install xhfsutil package.

Never used Mac CDs/DVDs, so I cannot really help with that.
But:
hfsutils is a set of command line tools to access HFS volumes/disks, similar to mtools.
They don’t add anything to the kernel (or /proc/filesystems).

You can e.g. use “hls” to list the directory, “hcopy” to copy files, and so on.
hmount would sound like it could mount things, though.

And there is a GUI, “xfhs”.

Although, AFAICS, openSUSE’s kernel package does come with hfs/hfsplus support as a module.

$ rpm -ql kernel-default | grep -i hfs

I guess I wasn’t clear enough that I have already done that.

So, how do we get that working, then?

It should just work, you should just be able to mount hfs partitions.
You could try to pass “-t hfs” (or “-t hfsplus”) to mount to disable autodetection and force hfs(plus).

But maybe CDs/DVDs are not supported, no idea.

Have you tried to use the hfsutils already?
(installing them alone is not enough)

xhfs sends plasmashell into 25% CPU burn on my i7 4790K, so that got deleted immediately. Looks like it hasn’t had any work to update it since 1998 …

Hi
Well hfs is already in /etc/filesystems add hfsplus as well? It will
use as required.

No effect.

I have since dragged an old PowerMac out of the closet and am using it to copy the files. Silly to have to hook up an entire second computer just to read some CDs, but that’s what’s happening.

I ask again: have you actually tried to use the hfsutils command line tools (hls, hcopy, hmount) ?

The man page suggests they should support CDs:

Or did you try “mount -t hfs /dev/sr0 /mnt/cdrom” or similar as I suggested as well?

PS: hmount apparently “mounts” a disk for use with the other hfsutils, it does not really mount it into the system.
https://linux.die.net/man/1/hmount

hmount does not actually mount an HFS partition over a UNIX directory in the traditional mount(8) sense. It is merely a “virtual” mount, as a point of convenience for future HFS operations. Each HFS command independently opens, operates on, and closes the named source path given to hmount.

So as I understand it, e.g. one way to list the CD’s directory would be:

hmount /dev/sr0
hls
