Format a protected (corrupted) sd card
I have a linux command for you: hdparm
Set the readonly flag, card will be readonly:
markus@markus-ThinkPad-W530:~$ sudo hdparm -r 1 /dev/mmcblk0
/dev/mmcblk0:
setting readonly to 1 (on)
readonly = 1 (on)
Clear the readonly flag, card wil be read-write:
markus@markus-ThinkPad-W530:~$ sudo hdparm -r 0 /dev/mmcblk0
/dev/mmcblk0:
setting readonly to 0 (off)
readonly = 0 (off)
Query the readonly flag, 0 = readwrite, 1 = readonly:
markus@markus-ThinkPad-W530:~$ sudo hdparm -r /dev/mmcblk0
/dev/mmcblk0:
readonly = 0 (off)
