I have a laptop running on Ubuntoo. My friend has given me some text file to copy a data from removable media to the laptop. Similarly when I connect the external drive and access in command line mode then the screen returns ENODEV error. What does this means. Second thing I am trying to open a text file in the same way two new errors come up. They are ETXTBSY & EFBIG on the screen. Need some solution for the same. Thanks.
