I have just installed ubuntu 12.10 and everything is running fine but there are a few things that I am not sure about.
In computer, when I click on the hard disk it says "unable to mount location - can't mount file" and when I right click it the type/size/volume/accessed/modified are all unknown. However everything seems to be partitioned correctly.
Also, when I right click file system properties it lists the correct amount of free space, but volume is unknown and the contents reads as 140 TB.
As I said everything is working fine but are these issues I should be concerned about?
