[ubuntu] Can't get data from exernal hard drive

view story

http://ubuntuforums.org – Some time ago I did something wrong trying to make a bootable USB using my external hard drive. It had to be formatted, but I didn't proceed the operation (when I got, what was going to happen). Now I still have the data on the hard drive -- when I go to Properties, I see 440Gb used and 60 Gb free space -- but I can't reach it. Could you tell me please, is there any way I can do it?
