Is there a minimum size that Nero needs / wants before it can write to a CD? I have two files totalling less that 7MB I need to write onto 400 CD's. When I tried the first one it did not work: Nero could not verify and no data was actually written. Any suggestion.
Should not happen. You should be able to write 0 or 1 byte sized discs if you’d want to.
Try the Nero Burning Rom shortcut, not Nero Express.
