Ubuntu 9.04: Ripping CDs with grip?

Question

I tried to rip a CD tonight, and couldn't figure out how to configure grip - /dev/cdrom doesn't seem to be the mount point for music CDs any more.

How can I configure grip to find CDs?

Update:

/etc/fstab has

/dev/scd0       /media/cdrom0   udf,iso9660 user,noauto,exec,utf8 0       0

But there's nothing visible in /media/cdrom0 (or /media/cdrom, which is a symlink to cdrom0)

There's an icon on the desktop labeled "Audio Disk" and opening it shows the .wav files on the CD. The location is cdda://sr0/, but grip doesn't like that either.

Trying to manually mount /dev/sr0, I get

$ sudo mount -t auto /dev/sr0 foo/
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: you must specify the filesystem type

Update 2:

Tried to change the media handling preferences (From a file browser, Edit->Preferences, Media, CD Audio) to "Do Nothing". CD Still doesn't mount.

Update 3: With an audio CD in the drive:

$ ls -l /dev/ | grep cd
lrwxrwxrwx  1 root   root             3 2009-09-15 22:13 cdrom1 -> sr0
lrwxrwxrwx  1 root   root             3 2009-09-15 22:13 cdrw1 -> sr0
drwxr-xr-x  2 root   root            60 2009-09-15 22:13 pktcdvd
lrwxrwxrwx  1 root   root             3 2009-09-15 22:13 scd0 -> sr0
crw-rw----+ 1 root   cdrom      21,   2 2009-09-15 22:13 sg2
brw-rw----+ 1 root   cdrom      11,   0 2009-09-15 22:13 sr0

Answer 1

You don't mount a music CD. No. Never. Don't. They're not files. There's no filesystem. It's not iso9660. Or UDF. It's 16-bit stereo PCM at 44.1kHz, with a teensy bit of data overhead for track breaks, lead-in, lead-out, etc. You can't mount it. Stop trying. No, seriously, stop.

(If you've got a data section on an Audio/Data mixed-mode CD, you'll need to mount that to access the data, but for most audio CDs that's not necessary. Or, ya know, possible.)

Grip needs to know the device of your CD, and if that device is a SCSI device, needs the generic SCSI device as well. So check your /dev entries (/dev/cdrom or /dev/cdrom0 is probably a symlink to the proper device):

> ls -l /dev/cdr*  
lrwxrwxrwx 1 root root 3 2009-09-29 22:11 /dev/cdrom -> hdd  
lrwxrwxrwx 1 root root 3 2009-09-29 22:11 /dev/cdrw -> hdd

In this case, the device is straight IDE, and a generic SCSI device is unneeded; put "/dev/hdd" in the Config -> CD: CDRom Device entry.

Your system probably looks more like this (judging from your /etc/fstab posted above):

> ls -l /dev/cdr*
lrwxrwxrwx 1 root root 3 2009-09-29 22:11 /dev/cdrom0 -> scd0

Although, you did post this:

There's an icon on the desktop labeled "Audio Disk" and opening it shows the .wav files on the CD. The location is cdda://sr0/, but grip doesn't like that either.

So in Grip's configuration, you need to enter both of these:

1. Config -> CD: CDRom Device: /dev/sr0 (or could be /dev/scd0)
2. Config -> Rip -> Ripper: Generic SCSI Device: /dev/sg0

---

Update 1: Given this update on your configuration:

$ ls -l /dev/ | grep cd
lrwxrwxrwx  1 root   root             3 2009-09-15 22:13 cdrom1 -> sr0
lrwxrwxrwx  1 root   root             3 2009-09-15 22:13 cdrw1 -> sr0
drwxr-xr-x  2 root   root            60 2009-09-15 22:13 pktcdvd
lrwxrwxrwx  1 root   root             3 2009-09-15 22:13 scd0 -> sr0
crw-rw----+ 1 root   cdrom      21,   2 2009-09-15 22:13 sg2
brw-rw----+ 1 root   cdrom      11,   0 2009-09-15 22:13 sr0

You need to tell Grip to use

1. Config -> CD: CDRom Device: /dev/sr0
2. Config -> Rip -> Ripper: Generic SCSI Device: /dev/sg2

For the CD device, any of these should work. If the Generic SCSI device is not properly set, none of them will work.

• /dev/cdrom1 (symlink to sr0)
• /dev/cdrw1 (symlink to sr0)
• /dev/scd0 (symlink to sr0)

Update 2: this from a Jaunty user posting on the Ubuntu boards about this bug. (Fun related details at this kernel bug if you want them.)

The bug doesn't sound like it matches exactly what you're seeing, but the workaround may work for you. Basically, Grip and the HAL are conflicting over the CD device. A workaround is to disable the HAL:

Disable HAL polling of the sr0 device:

sudo hal-disable-polling --device /dev/sr0

This disables any HAL automounting of CDs and such, so you'll need to re-enable with this:

sudo hal-disable-polling --device /dev/sr0 --enable-polling

If this works, you might try running grip in a script sandwiched between the two above calls:

#!/bin/sh
sudo hal-disable-polling --device /dev/sr0
grip
sudo hal-disable-polling --device /dev/sr0 --enable-polling

Answer 2

Actually, /dev/cdrom is the device pointer, and not the mount point itself. The actual mount point will probably be found under /mnt/cdrom/ or a similar variant.

Try that instead.

Answer 3

How about /dev/sr0?

Update: The grip manual tells that you to try /dev/sg0

Answer 4

Look at /etc/fstab on your machine - that is where your CD drive mount point is configured. I'm running Ubuntu 9.04 (Jaunty), and the drive is configured to mount on /media/cdrom0.

Alternatively, pop a CD/DVD into the drive, wait a few seconds for it to be auto-mounted, and run the mount command to check the mount point.

$ grep cdrom /etc/fstab
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0

$ ls -ltr /dev/scd0
lrwxrwxrwx 1 root root 3 2009-09-24 12:38 /dev/scd0 -> sr0

$ mount |grep cdrom
/dev/sr0 on /media/cdrom0 type iso9660 (ro,nosuid,nodev,utf8,user=nagul)

Answer 5

mount: you must specify the filesystem type

You just have to set the filesystem type, since he seems not to be sure what he's tying to mount:

sudo mount -t iso9660 -o ro /dev/sr0 foo/
