http://ubuntuforums.org – I had tired to set it up as a bootable ubuntu drive BUT I stopped the process because that program was paused for a very long time. Now my jump drive says there is only 801mb on the drive even after I formatted it. It is supposed to be 4gb. I dont know what else to do. Thanks for you help in advance. (Hardware)
