I have to transfer roughly 250gb of data from a Master Drive to lots of USB drives, all of identical size and brand. When I copy using the GUI in Mac OSX, it waits to copy all the files to one drive and then copies the same files to drive 2.
Is there a way to copy the files across so that each file/bit is only read once and then written multiple times? This would presumably be faster than reading the same data over and over again. I have seen this question asked before, but I couldn't understand how the terminal commands worked.
Just so you know, I have very little experience with terminal, so if anyone has any great code, could they please explain how I would adjust it work with for me?
