I am currently trying to backup data from my computer's hard drive to an external one while live-booting to Ubuntu from a USB, and I've encountered a bit of a problem. You see, I cannot mount my hard drives.
I have been trying to mount directories in linux additively and fail to do so. I have three directrories a, b and c. a contains file x, b contains file y and c contains file z.
Now when i mount "a" and "b" into c and then open c there are only x and y present in "c". when i mount a, b and c into c the directory c is empty and ls says permission denied.
