How to rescue .wav files on the scratched music CD.

[Dennis N]

Do you know where is the mount point of the CD disk/DVD-Writer if mount GUI (via its icon) ?

I used the mount command and saw this line:

gvfsd-fuse on /run/user/1000/gvfs type fuse.gvfsd-fuse (rw,nosuid,nodev,relatime,user_id=1000,group_id=1000)

Then:

dmn@Sydney:~$ ls /run/user/1000/gvfs
'cdda:host=sr0'

so I can tell this is for the optical drive.

You can look up gvfs on Google to get information. Too technical for me.

BTW,

df -Th did not show anything on this connection.
and
lsblk -o name,mountpoint does not give a mount point for sr0. That column is blank for this device.

(Using Ubuntu 23.10)

It raises the question, why do we need a ripper application if we can just read and copy the tracks with the file manager?

Technically, you dont, but .wav's take up more space than FLAC, and aren't as friendly to tag.

Thanks for your advice.

For both working Audio Disc and problem Audio Disc

$ sudo mount /dev/sr0 /mnt/cdrom

mount: /mnt/cdrom: can't read superblock on /dev/sr0.

Why ?

To see mount points, use either the lsblk command or df -Th.
Beware that some "fake" mounts will be shown and sometimes gio/gvfs mounts don't get shown at all - i.e. fake.

Thanks

It is very strange.

File Manager shows all tracks of the problem Audio Disc but no mount point could be found. Please see attached screenshots

I couldn't play the tracks running VLC Media Play. The PC will freeze if playing any track.

But checking a working Audio Disc with "df-TH", also no mount point is found. Please see attached screenshot;

That is expected. Again, audio CD's do not have filesystems that mount normally. The system is using gvfs to make it look like a data CD. You can look at:

gvfs-mount

There's probably a way to copy the tracks like files with gvfs, but you are doing this the hard way. Use a ripper like k3b. It will check the disc for errors with libcdparanoia, convert from .wav to whatever format you want, and automatically name and tag the files for you. Or you can just rip to unnamed, untagged .wav files if that's really what you want for some reason.
