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

[satimis]

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.

If the music CD disc is working without problem of scratches, I can copy all track.wav files with copy&paste command seamlessly. This is a damaged music CD disc. I can't do it in the same way..

Performed following test:-
$ cd ~/Downloads/Test_folder/

$ abcde -a cddb,read,encode,tag,move,clean -d /dev/cdrom \
> -j 4 -o flac,vorbis:"-q 6" -V -x

.....

11: Il corsaro: Atto terzo. "Per me infelice" (Corrado, Medora, Gulnara, ancelle, corsari)
12: Il corsaro: Atto terzo. "O mio Corrado, appressati" (Medora, Corrado, Gulnara, ancelle, corsari)

I'm stuck here.

If the music CD disc is working without problem of scratches, I can copy all track.wav files with copy&paste command seamlessly. This is a damaged music CD disc. I can't do it in the same way..

If it won't automatically mount with gvfs like other music CD's and you can't rip it, then the disc is probably damaged too badly, especially if a normal CD player can't read it. Even if you get the right gvfs mount command, it's not going to work in that case. I hope I'm wrong, but good luck..

How it works (to the best of my knowledge):

A ripper works one track at a time using location information in the CD's table of contents (TOC). If the TOC of the CD is damaged, the start bit of tracks may not be readable. So it can't be ripped. There is no fix. If you bought the CD, You need to get a replacement.

This is an old music CD

OK

Let me try a working music CD disc first.

What command shall I execute to copy all output of
$ gio list cdda://sr0

to a folder after | command

Thanks

If it's a good playable CD, then I have only used the GUI ripper/encoders. For example, asunder. It has a preferences dialog with all the encoder settings, like destination, encoding format (mp3, aac, flac, etc), quality, and the format for what the file names look like. I can't advise on the gio thing you show.

If it's important to replace, being old doesn't mean you can't find another for sale on the internet. New or used.

You might try using ddrescue to create an image of the CD on disk. ddrescue (gddrescue package name) will keep trying to get all the data is can, assuming the device can be seen by the OS. Let it have 5+ passes to try. If it finishes, then it thinks it got the data/iso. Then you cal look up the specific loop mount required to open it for ripping. The resulting file is like pointing at a real disc device.

This is just a lead. I can't provide exact commands or steps. Sorry. I've never used it with a music CD, but I have used it with data disks that also had 10% par2 files. It worked well enough that no data was lost.

Try this (although my CD was not damaged)
It will copy all the tracks.

cp -r /run/user/1000/gvfs/cdda:host=sr0 ~/Downloads/Test/

N.B. Your destination folder has a slightly different name.

For good music CD disc

$ cp -r /run/user/1000/gvfs/cdda:host=sr0 ~/Downloads/Test_folder_3/

$ ls Downloads/Test_folder_2/

'cdda:host=sr0'

$ ls Downloads/Test_folder_2/cdda\:host\=sr0/

'Track 10.wav'  'Track 15.wav'  'Track 1.wav'   'Track 24.wav'  'Track 6.wav'
'Track 11.wav'  'Track 16.wav'  'Track 20.wav'  'Track 2.wav'   'Track 7.wav'
'Track 12.wav'  'Track 17.wav'  'Track 21.wav'  'Track 3.wav'   'Track 8.wav'
'Track 13.wav'  'Track 18.wav'  'Track 22.wav'  'Track 4.wav'   'Track 9.wav'
'Track 14.wav'  'Track 19.wav'  'Track 23.wav'  'Track 5.wav'

For damaged music CD disc
It can be mounted

On File-manager:
It also shows all track .wav files

$ mkdir ~/Downloads/Test_folder_3
$ cp -r /run/user/1000/gvfs/cdda:host=sr0 ~/Downloads/Test_folder_3/
It holds there for prolonged time, no files copied.

cdrdao (see the link in post #27 by tea for one) looks like it is a utility that would help in recovery when the TOC has errors. It's new to me and I'm making note of it if ever needed. I suggest you try what is done there. It's probably already installed (see below). So there is a way to possibly recover the music, but the original CD will never play again. All you can do is burn a new CD once all the music is recovered.

Possible useful utilities for your task:

brasero/mantic 3.12.3-2 amd64
  CD/DVD burning application for GNOME

cdrdao/mantic,now 1:1.2.4-3 amd64 [installed,automatic]
  records CDs in Disk-At-Once (DAO) mode

cue2toc/mantic 0.4-5.1 amd64
  converts CUE files to cdrdao's TOC format

post #27 is for Linux Mint. I'm now working on Ubuntu 22.04. I don't know whether the steps work here?
