I have used Ubuntu before using Wubi but, I found that I needed the extra space which I installed Ubuntu in. I have tried VirtualBox for Windows and Mac to try to full install Ubuntu, I even installed the extension pack and updated it. But it will not work, on Mac it greys out the USB device are when I try to attach it to the virtual machine. In Windows it attached but Ubuntu couldn't detect it. Unfortunately it had to be formatted to HFS as NTFS wouldn't work. Any ideas on how to get this working? It's a 1TB WD My Book Elite though I doubt you needed that info. I hope it will work or this thing will sit gathering dust forever.
