I've installed Ubuntu 12.10 on a USB stick it kept running very well and I could access my hard disk and other removable media, until suddenly I can't access the hard disk and any other removable media and I get this message every time I click on the hard disk item from the file browser.:

Error mounting /dev/sda1 at /media/ubuntu/1C489D42489D1B98: Command-line `mount -t 
"ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=999,gid=999,dmask=0077,fmask=0177" 
"/dev/sda1" "/media/ubuntu/1C489D42489D1B98"' exited with non-zero exit status 21:
mount: according to mtab, /dev/sda1 is already mounted on /media/ubuntu/1C489D42489D1B98

Are you able to access the partition through /media/ubuntu/1C489D42489D1B98 ? If yes, you may create a shortcut to this folder as a workaround. I don't know why ubuntu tries to mount it again.
