##dmesgでSDカードのマウント先を検索

なんかバーッーと出る。

[ 105.319267] mmc0: card 1234 removed
[ 109.679864] mmc0: new ultra high speed SDR50 SDHC card at address 1234
[ 149.680068] mmcblk0: mmc0:1234 SA32G 28.9 GiB (ro)

##SDのマウント先で、それっぽいの探す。

"mmcblk0" がSDっぽいので

SDをDDイメージにして、ホームフォルダへ。"user"は各自の環境で。

$ sudo dd if=/dev/mmcblk0 of=/home/user/image.dd | watch -n 10 pkill -USR1 dd

DDしたイメージを、SDへ。

$ sudo dd if=/home/user/image.dd of=/dev/mmcblk0 | sudo watch -n 10 pkill -USR1 dd
