My acer laptop broke a while back and I took the 250GB out of it and put it in an enclosure and I am now using it as a portable hard drive. The problem is it still has windows vista installed and loads of other things that are taking up 30GB on the hdd. It won't let me delete them when I try. It also still reads it as a partition so when I plug it in it comes up with 2 drives.
How do I remove all the windows files and the partition on this hdd?
