I already updated the firmware, but if I put in my RED Mag the option to save copy isn`t available anymore. Only the Buttons Copy and Varify and Fast Copy are choosable.
What is the model number of your Nexto?
In some specific case, 'Safe Copy' is not recommended to prevent accidental error.
For example,
1. Connected through Multi LUN USB card reader.(Where more than one memory slot exist)
2. If the memory card has some cluster chain related error, etc..
