[SOLVED]mounting cdrom and usb devices doesn't work

Hello,

i have trouble mounting my usb devices. automount doesn't work and i can't mount them manually even as a superuser. here's the output of mount command:

mount: wrong fs type, bad option, bad superblock on /dev/sdc,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

i can mount cdrom manually but i can't do the same for my usb stick and external hard drives. it always complains about the above regardless of the filesystem. my devices are working under windows and other linuxes so i know hardware is not the problem.

i'm using lxde with pcmanfm.

if you need any other files just ask.

thanks

Re: [SOLVED]mounting cdrom and usb devices doesn't work

Have you followed the HAL wiki page especially the Trouble Shooting section? Follow the instructions for PolicyKit. That should make it work.

Also use the search function of the forums...this issue has been discussed a lot of times.

Re: [SOLVED]mounting cdrom and usb devices doesn't work

I presume the above was trying to mount a cd? (it may help if you give the actual mount-command!!)
If it was an attempt to mount a usb-stick, then it most certaily should have been:
mount /dev/sdc1 /some/path/mountpoint

cd's and floppies (in general) are the only devices that can be used without partitioning, even floppies will often have a partition on them.

the hal policy-kit stuff should not affect your ability to mount anything as 'root'.

Re: [SOLVED]mounting cdrom and usb devices doesn't work

above was the error when i tried to mount any usb device with "mount -t <type> /dev/sdc /media/mountpoint". and i couldn't mount any usb device as root from console. when i tried to mount devices using pcmanfm it just popped some empty dialogs and i couldn't find any mention of "IsCallerPriviliged failed" error so i (wrongly) presumed it wasn't that. i did try some of the other fixes mentioned in the forum with no success. but adding exec ck-launch-session startkde to my .xinitrc fixed the issue

thanks again

Yup - because you used /dev/sdc and not /dev/sdc1 !!
