I am a newcomer to Ubuntu. I was not really sure if I should install Ibuntu on my HDD, but now I am sure it is not a bad go, but I have installed Ubuntu 20.04.01 LTS in my USB (128GB SanDisk), and I want your help to safely send my files to /dev/sda3.
I thought I could copy & paste the files when I use Windows 10.
The USB would not open the file (pop-up saying I should format the drive), also sometimes when I mount my disk it reads the folders as read only (but next time I startup it won't). Can anyone help me out and, try to explain the steps?
