i tried "fdisk",but when i execute"fdisk /dev/mmcblk0",system is down.


i tried again with a sd card that i canfix it use card reader.

1,insert a formatted sd card, powerup, txt out:.....14.8Gb/mmcblk0p1;

2,execut"fdisk /dev/mmcblk0",type "m" for help,and type "d" for delete patition,type "w" and quit, powerdown;

3,powerup,txt out:....14.8Gb/unknown patition table;

4, i can not do anything unless put the sd card to cardreader and format with PC.
