Ubuntu – Can’t open a separate usbdrive when booting from a liveusb install 12.10


My problem is using a separate flash drive when running from my live usb of ubuntu 12.10. The problem is that when I choose to Try Ubuntu from this usb drive it no longer lets me access my other flash drive. It automatically sets it to part of the live usb but it's a completely separate flash drive.
Ubuntu loads fine and everything but when I go to access my other flash drive nothing happens. When I try to open it from the home folder it gives me
Unable to mount 3.5 volume
Adding read ACL for uid 999 to media/ubuntu failed: Operation not supported message.
My live usb is on a 8gb flash drive and my other flash drive is 4g.

There was change for 12.10 where the mount point for automount devices is now in /media/username. Previously the mount point was in /media. I'm not sure why they changed it, but it seems like that the creation for /media/username at boot time was forgotten for the LiveUSB/DVD.

Try making the directory and see if the automount now works:

sudo mkdir /media/ubuntu

If that doesn't work, try mounting manually:

sudo mount /dev/sdc1 /mnt

...assuming the device you are trying to mount is /dev/sdc. The mount point will be /mnt, or you can use /media/ubuntu if you wish since you just made it.
