External storage device not mounted automatically

Hello,
I when i plug an USB storage device, it isn't mounted automatically. Instead, i have an error message:

Error mounting: mount exited with exit code 1: helper failed with:
Unprivileged user can not mount NTFS block devices using the external FUSE
library. Either mount the volume as root, or rebuild NTFS-3G with integrated
FUSE support and make it setuid root. Please see more information at
http://ntfs-3g.org/support.html#unprivileged

The thing is, the error occur even when the device has no NTFS partition...

Re: External storage device not mounted automatically

Did you check Hal Troubleshooting already?

Re: External storage device not mounted automatically

I thought devicekit-disk/udisks and HAL were two differents things ?

Re: External storage device not mounted automatically

I think you have an issue with privileges, have you tried editing the permissions with chmod?

Re: External storage device not mounted automatically

Please post the output of 'fdisk -l <device>'.

Re: External storage device not mounted automatically

I fixed the problem with 'ntfsfix /dev/<ntfs-partition>'. I've also updated the NTFS-3g wiki page.

Re: External storage device not mounted automatically

Thanks, but i have no NTFS partitions on my devices. And this is why this error message is so weird...

Re: External storage device not mounted automatically

Probably not the solution you want, but you can automount with udev instead of udisks - details in the wiki.

Re: External storage device not mounted automatically

I recompiled udisks with debug flags and debugged it using GDB, and i found the cause of my problem...
I already had an entry for /dev/sdb1 in my /etc/fstab specifying it as a ntfs partiton. I did that a long time ago, for another device, and forgot about it.
I think i need to read http://wiki.archlinux.org/index.php/Per … ice_naming
