Automount of external harddrive fails after install from USB CD drive

[Henning Carstens]

It's a USB hard drive with one ntfs partition. When pluggin in it says

Oct 15 19:02:45 fusel kernel: [ 6547.624017] usb 8-5: new high speed USB device using ehci_hcd and address 5

Oct 15 19:02:51 fusel kernel: [ 6553.317529] ISOFS: Unable to identify CD-ROM format.

So it seems the automounter thinks it's a cdrom drive. When I click on "hc extern" (the partition name) in Gnome's location bar, the two last lines repeat (UDF-fs etc.). There is also a error popup:

--
Cannot mount volume.
Invalid mount option when attempting to mount the volume 'hc extern'.
--

Manual mounting works:
# mount -v -t ntfs-3g /dev/sdb1 /media/hc\ extern/
(no message, it just works)

I'm using Ubuntu 8.10 beta. Please answer, if more info is needed. I don't know which program is responsible for automounting...

Can you please post the output of the following commands with the drive plugged in, I think it may be conflicting with an entry in /etc/fstab

sudo fdisk -l
cat /etc/fstab
sudo blkid
mount

[Richard Gash (rdgash)]

I have the same problem, no automount of usb external drives, I can maually mount the drive okay using
mount -v -t vfat -o noatime /dev/sdb1 /media/sdb1. When plugging in the drive, popup appears saying, cannot mount volume, invalid mount option when attempting to mount the volume 'VOLNAME'
 results for requested info is attached

[Henning Carstens (mail-henning-carstens)]

Solution: I installed Ubuntu with a USB stick, probably with /dev/sdb1 as a device descriptor. So I had two lines for CD-ROM in /etc/fstab:

/dev/sdb1 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
/dev/scd0 /media/cdrom1 udf,iso9660 user,noauto,exec,utf8 0 0

When I remove the first one (or add a # before it), everything works fine.

There even was a hint in the documentation (https://help.ubuntu.com/community/Installation/FromUSBStick), I did not see at first.

Thanks for the help.

Since this is not an actual bug, I am setting it to Invalid (Closed) instead of Fix Released. Richard, you should file a help request on the Answers part of Launchpad, or on the Ubuntu Forums.
Thank you.

[Richard Gash (rdgash)]

Thanks,
I was able to fix this by removing the cdrom definition for sdb1 in fstab. I
do respectively disagree about this not being a bug, I believe it to be an
installation related bug. The fstab was created from a fresh 8.10 beta
install from cdrom, the entry for sdb1 should not have been present in fstab
and was apparently placed there during the install process.
Thanks for you help,
Richard

It's a duplicate of bug 150872 (https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/150872).

An I agree with Richard: It's a bug. Non-CD installations are getting more important due to "Netbooks" and cheap flash storage.

The installer even detected my CD-ROM, why didn't it detect that the USB stick is a removable device?

So in my opinion it's a bug and removing the line in /etc/fstab is only a workaround...

[Connor Imes (ckimes)]

Ahh, you are correct, I misread "I installed Ubuntu with a USB stick" for "I installed Ubuntu on a USB stick". I will mark this bug as a duplicate. Thank you.
