I have tried all possible combinations of chmod but I still cannot access one partition of my hard drive where I keep all my data. I am using Ubuntu 10.04. I have to boot up Puppy Linux to change the permissions. Then after I boot up Windows 8 to play WoW, and come back to Ubuntu, I am locked out of that data partition again. Has this got anything to do with the way Windows 8 takes ownership of the partition?
