Possibility to format card

[simon88]

Hi

It would be nice to have the possibility to format a SD card, for example I'm working with https://learn.adafruit.com/adafruit-spi-flash-sd-card/overview Adafruit module and now my card is bricked so the module is ready to go to the trash because I've no possibility to try to format it.

The "SdFat" library does provide a formatting capability:
