Karmic stopped automounting USB drives and internal DVD

[Elwro]

Hi,

yesterday my 9.10 stopped automounting my external USB drive, and in general any pendrive I put into any USB slot. What's worse, it also does not recognise CDs put into my DVD drive. (The only update I recall doing was the official update to the "sudo" package.)

1. The USB issue.

I plug in my external hard drive. Seemingly, nothing happens. No new icons appear anywhere.

a) Still,

sudo fdisk -l

gives, among other things:

Disk /dev/sdc: 999.5 GB, 999501594624 bytes
255 heads, 63 sectors/track, 121515 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x0002ae3f

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1               1      121516   976074752    7  HPFS/NTFS

and I can mount it "manually" without any problems. Similarly for my pendrives. But I don't want to do it any time I put anything into the USB slot and I have no idea why this function stopped working!

b) I tried gconf-editor and in apps -> nautilus -> preferences "media_automount" is set to YES.

c) After searching around these forums, I even put "usb_storage" into /etc/modules and

<match action="org.freedesktop.hal.storage.mount-removable">
    <return result="yes" />
</match>

into /etc/PolicyKit/PolicyKit.conf and restarted HAL. Still doesn't work!


2. The DVD drive issue.

I put an audio CD in the drive. Usually an 'Audio CD' icon appeared after a few seconds, but now nothing happens. There is a "cdrom0" icon visible in the explorer, but when I click it, I get the following error:

Unable to mount cdrom0

mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

The output of 'dmesg | tail' with the audio CD in the drive is

$ dmesg | tail

[  181.163527] isofs_fill_super: bread failed, dev=sr0, iso_blknum=16, block=16

edit: the output stays the same when I take the disc out from the drive.


So, it seems that for some strange reason my Karmic stopped being able to automount any new media. Does anyone have an idea why it is so and what should I do to bring this much-needed functionality back?

[aadam12]

Same problem here. Just started happening for no apparent reason. Was there some update to Karmic that killed the automount?

[Endomancer]

It happened to me too, I can't mount CDs or DVDs either, in the Places menu I got cdrom0 showing but when I click on it I get

[ CODE ][ /CODE ] Unable to mount cdrom0

mount: special device /dev/scd0 does not exist [ CODE ][ /CODE ]

USB's have been auto mounting as normal for me and after reading this thread I decided to see if my 8 in 1 card reader will finally mount (it previously wouldn't) and I was able to manually mount an SD card through Disk Utility in System/Administration, now it auto mounts.

What does cat /etc/fstab say? You all still got a /dev/scd0? How does fstab look? Something up there?

$ cat /etc/fstab

/dev/sda3 /media/Nowy3 ntfs rw 0 0
/dev/sda2 /media/Nowy2 ntfs rw 0 0
/dev/sda1 /media/Nowy1 ntfs rw 0 0

The external USB drive is recognized by fdisk as /dev/sdc1.

It turns out I CAN mount a DATA DVD just by clicking the "cdrom0" icon. And VLC can play audio CDs from /dev/sdc0, without mounting.

Me too. Everything looks fine in dmesg, I get a

(rhythmbox:31115): GVFS-RemoteVolumeMonitor-WARNING **: invoking IsSupported() failed for remote volume monitor with dbus name org.gtk.Private.GduVolumeMonitor: org.freedesktop.DBus.Error.Spawn.ChildSignaled: Process /usr/lib/gvfs/gvfs-gdu-volume-monitor received signal 11

in xsession-errors but not sure if that's related. I have a few PPA's I'm using though, maybe that has something to do with it?

[Elwro]

I also have some regarding gvfs. Both the output of "dmesg |tail -n 50" and the content of /var/log/kern.log.1 contain similar instances of

[ 2421.233165] gvfs-gdu-volume[3447]: segfault at c ip 00c5ffa7 sp bff612bc error 4 in libgdu.so.0.0.0[c4d000+31000]

I have no idea whether this is in any way relevant, though, since such "segfaults" appear in the kernel log even a few days before I started having any problems.

When you mount a drive is it visable on desktop? If not use the panel right click
add to panel and to disk mounter for time being.
I have same problem but in Lucid 10.04 Places just shows Computer and cdrom0
when it used to show karmic install and windows 7 install.

rick@rick-laptop:~$ sudo mount /dev/sdb1 /media/KINGSTON
rick@rick-laptop:~$ sudo umount /media/KINGSTON
rick@rick-laptop:~$

This of course is how I have been mounting USB and internal drive partitions for now.
space after sdb1.

Your fstab looks good mine looks good but nothing in Places drop down menu and never have had cdrom0 there. Karmic install still looks and works smooth as butter, I thought this was a Lucid thing. Now you come up with it in Karmic. Got to get into this now and try to figure out. Keep in touch on this thread, I am.
Can still mount all from Terminal as long as you have a label like KINGSTON for mine.
Go to gparted in Admin and right click on partition and Label it is just easier. From then on it is always /media/ (whatever you label). Just in case a reader needs to know this.
Strange it is in Karmic though but very interesting.

[garvinrick4]

Disk mounter does not let me umount a disk, it does not believe I am root nor ask me.
Got to be something in there that we might have done maybe. Nobody in Lucid is complaining about this and not many in Karmic. What did we do? And not having partitions in Places I thought was going to be something new in Lucid Lynx. It is only Alpha so was just going along since could still mount just had to be from Terminal. HMMMM

So far I have tried data DVD, DVD movie and audio CDs with no difference
in Disc Utility my DVD burner doesn't even show on the list of drives.
USBs have been mounting as usual and SD cards can now automount since the sudo update which is a small yay
but at the price of no CD/DVDs is not so yay
