Error - kio_media_mounthelper when removing USB

[Gumper]

Is anyone else having problems when selecting the "Safely remove" option for a mounted USB drive? When I do this I get 2 messages on the screen. The normal one saying that the data is being sync'd and the following error message:

"Error - kio_media_mounthelper when removing USB"

The device is unmounted but the error message is a little annoying.

Thanks

Re: Error - kio_media_mounthelper when removing USB

I did some checking into this and if I use the command "kio_media_mounthelper -u media:/sdd1", I'm able to unmount without any eject errors. If I use "kio_media_mounthelper -s media:/sdd1", I receive the error. When you select 'safely remove' from the GUI menu, it calls "media_safelyremove.desktop" which executes "kio_umountwrapper". This wrapper then calls "kio_media_mounthelper -s media:/sdd1". If I can figure out how to call this without the 's' option, I think I'd be alright.

I could edit "media_safelyremove.desktop" to just execute "kio_media_mounthelper -u media:/sdd1", but then I don't have the progress dialog.

Could someone check if they are able to remove a USB stick without getting any errors?

Thanks

Could someone check if they are able to remove a USB stick without getting any errors?

Usb flash disk mounts Ok but with the "Safely Remove":

Error-kio_media_mounthelper

The device was successfully unmounted, but could not be ejected.

As you noticed:

executes "kio_umountwrapper". This wrapper then calls "kio_media_mounthelper -s media:/sdd1". If I can figure out how to call this without the 's' option, I think I'd be alright.

Thanks Rog131. I will give this a try. I wonder why I'm having this problem now. I didn't have this issue with Gutsy Gibbon.

Re: Error - kio_media_mounthelper when removing USB

Hi, I've got exactly the same problem (on hardy). It has probably something to do with permission rights. I can manually eject my usb stick with sudo (from console), but I cannot do the same without it. To unmount the device however I don't need sudo. My guess is one of the recent upgrades was messed up. Simple change of "unmount and eject" to "unmount only" doesn't solve the problem. I've seen something like this before on debian. It took me a while to solve it. I had to add my user to plugdev group to make "remove safely" option work again (not this time though). Anyway, closer look on /etc/groups file might help.

I added a comment.

PS A possible solution for the desperate ones - adding user to every group on system one by one (and hope the correct group is actually there).

PS2 I checked permissions on /dev (root/root) and /dev/sdh1 (my stick - root/disk). Add your users to the disk group and everything should be fine. It worked for me.

Same problem here.
On laptop, desktop, using multiple flash disks or removable HDD.
7.10 had no issues, so it must be with Hardy 8.04
