我可以
- 读当我的微型 SD 卡处于“锁“ 位置
但当我尝试时事情变得很奇怪“开锁” 它：我没有办法
fsck它，也不- 安装它，也不
- 读过，也不..
- 格式化它！
我需要格式化它，我该怎么办？
这是我的gparted输出：
$ sudo gparted
Created symlink /run/systemd/system/-.mount → /dev/null.
Created symlink /run/systemd/system/boot-efi.mount → /dev/null.

点击Device -> Create partition table
选择msdos, Apply, 稍等片刻
Ignore
然后它开始在这两个错误消息之间循环，直到最后
Cancel。
取消后，状态栏显示
有一段时间，然后
mmcblk0..无论如何，左上角的框中不再可见。
知道可能出了什么问题吗？
如何格式化我的 SD 卡？
难道只是死了吗？
[编辑]更多信息？当插入解锁状态时：

哦好的..
$ sudo e2fsck /dev/mmcblk0
e2fsck 1.43.4 (31-Jan-2017)
e2fsck: Input/output error while trying to open mmcblk0
The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
or
e2fsck -b 32768 <device>
..建议的命令都产生相同的输出。

现在尝试gdisk玩亚历克斯·贝瑞：
第一次尝试，两个分区都已安装：

..我很高兴错误消息（no5）至少与我最深层的想法一致！
拔卡重启..
现在扫描设备后根本gparted不列出：/dev/mmcblk0
