[edit] My SD card stops working? Do I need to reformat it again? Why does this happen?

If this is not done then the SD card may get corrupted and may need to be reformatted. If “Busybox” is installed on the platform a "sync" command should also be ran prior to removing the SD card from the device. This will prevent SD cards from corruption.
