I have a large file (67 gb) in my external hard drive. Every time I tried to copy the file to the desktop from my external drive, transfer stops at the exact same percentage. If the file size is small I can copy it without any errors from the same hard disk (like 10 gb). I honestly have no idea what is going on. Can someone please help me. I need this file for my new project it is literally life and death for me at this stage.
