Mounting audio CDs

[mb720]

Hi!

Is there a way to mount CD-ROMs with udiskie?

I tried udiskie-mount /dev/sr0 but the error message said it was an unhandled device.

Hi,

mounting CDs should be possible. What is the output of udiskie-mount -v /dev/sr0? It should display which rule was used to discriminate against the device.

The output of udiskie-mount -v /dev/sr0 is

Hi,

thanks for the output! Looks like the device for the CD drive is not properly handled by the cases in Mounter.add. I put this on my TODO for the next release, but I can't promise making it timely, I'm afraid.

Best, Thomas

Thanks for looking into this! :-) There's no rush, by the way.

Hi, I reinstalled a CD drive in my laptop (:D) and couldn't reproduce the issue. In order to determine what might be the problem, it would be helpful to also have the output of udisksctl dump, everything for /dev/sr0 and the object listed as its drive.

[coldfix]

One issue that I found is that it can take relatively long for the filesystem to be recognized (depending on the CD drive and the quality of the CD/DVD) such that udiskie will consider the device unhandleable for a certain amount of time.

I forgot to mention that I tried to mount an audio CD; udiskie works flawlessly with a CD that contains files: it mounts the CD's file system automatically. :-)

I'm not sure it's possible to mount an audio CD, is it?

For audio CDs, I can get the tracks using abcde anyway.

For the record, here's the output of udisksctl dump for the audio CD:

Hi,

I'm no expert in these things, but from google research it's not possible to mount audio CDs.

This also agrees with the fact that udisksctl dump doesn't list a org.freedesktop.UDisks2.Filesystem interface for the CD.

Should you happen find that there are indeed drivers that allow exposing the audio tracks as a filesystem, please let me know here (for my curiosity and future readers).

I'm closing this for now since you say that normal data CDs work.

Best, Thomas

This did not work for the audio CD:

sudo mount -t iso9660 -o ro /dev/sr0 /run/media/mb/

Got an error:

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