Nj series SD Card not backing up

[Maher Salem 0]

I have a SD Card on NJ series cpu don't accept the backup

I formatted it by using PC  and can't do backup from cpu

What is the causes ,?

Is the formatting by computer affect the SD card ?

If there is a password on cpu will it prevent me to format or intialize  the card by using sysmac studio ?
