I can't unmount usb flash disks

[puratu]

hello. When I try to unmount a flash disk, I get this:

This happens if I try to unmount it by clicking "Safely remove" after copying some files to it. What should I do to get rid of this?

I'd first try removing the spaces from the mount point (e.g. set it to /media/stone_plus).

You can also replace the 'space' with '\040' instead. So, instead of having:

/media/Stone Plus

you have:

/media/Stone\040Plus

Also make sure you don't have any files open that are on the drive. Close all files before trying to unmount.

I don't think it's about that space because I didn't have such a problem with other distributions with the same device That's my mp3 player and I'm having this problem with all usb drives. Any other ideas?

If you are running Feisty Fawn, you may have to unmount media as root.

If it's in your fstab, could you post the entry?
If not, after inserting it, execute "mount" and post the line applicable to this drive.

It's not in the fstab.
Here is the "mount" output:

/dev/sda1 on / type ext3 (rw,errors=remount-ro)

Hmm...
Could you also post the output of "groups"?

Re: I can't unmount usb flash disks

Hmm... Everything looks fine.

How are you mounting it? Just sticking it in and letting KDE mount it?

Have you tried unmounting it as root? I know from experience, sometimes you have to unmount media as root.

The point is to not have to unmount it as root. And you said that already.

And I also had a thought. Try sticking this in your fstab:

/dev/sdb1 /media/disk auto rw,nosuid,nodev,noatime,user,uid=1000,gid=1000,utf8,shortname=lower

Though I'd recommend looking up the UUID (look in /dev/disk/by-uuid) and selecting a different mount point.
