I have a problem with how to format an SD card without a computer. Suppose my SD card is connected to a Pi 3 and this Pi is in a package. As soon as the package is opened, even in power off mode the SD card is broken or formatted. how do I do this?
My idea is that with a battery powered device, it can be unusable or even formatted by connecting the base of the sockets or by applying high voltage.

Oh my goodness, your question is the hardest to understand. No wonder even the seriousEnglish.stackExchange guys could not handle, and send it to us.
Let me try to guess your question.
- You ordered a Rpi together with a SD card [not sure if you ordered an empty card, or one with OS preinstalled.]
- The package arrived [by express delivery, I guess].
- You opened the package and found the Rpi, together with the SD card [which you somehow know is either broken or formatted].
- Now your question. Is it true that either using battery power, or wall wart power to supply the Rpi, you cannot use it or format it?
I gave up. You reminded me that when I was small, I learnt English by listening to the radio, and my English teachers then were The Carpenters, Bee Gees, and Elvis Presley, and their English is very easy to understand! 🙂
