Help, I can't mount USB devices

[aManFromOuterSpace]

Hi again,

Something very strange has happened. For some reason when I plug in a USB device into my F12 rig up pops a error saying,

Unable to mount <name of device> file system
Not Authorised

When I try to mount from the CLI I get,

mount: can't find /dev/sdb1 in /etc/fstab or /etc/mstab

I'm not really sure what this is telling me or what I need to do to fix it.

Thanks

Is this a change? When you previously plugged in a USB device, was it recognized and now it is not?

Are you doing the mount command as root?
What command do you use to mount manually?

[aManFromOuterSpace]

Yeah it previously worked fine, I'd plug a usb stick in and then up would pop the filesystem contents.

A manual mount can only be done as root, I get the message quoted second in my first post.

The only way I can navigate a connected device is to mount manually using "mount /dev/sdb1 /mnt"

If you're doing mount -a, then it mounts according to your fstab file. Normally you would not have an entry for a USB stick in fstab, since HAL takes care of mounting.

That error usually indicates something weird with your consolekit/polickity session.

The Arch wiki entry on HAL has some possible solutions.
