踩

probing the target board failed.

搞了个电信的android手机，结果送了个sd卡有点问题，在windows下试了多种办法都不行，既不能修复，也不能低格，于是尝试在linux下格式化试试。

将sd卡插入读卡器，就自动挂载了，所以要先卸载。

$sudo -i

取得root权限

# mount

可以看到最后一行的设备号

/dev/mmcblk0 on /media/FCC8-85C1 type vfat(rw,nosuid,nodev,uhelper=udisks,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush)

umount这个sd卡

# umount /dev/mmcblk0

然后使用fdisk工具

# fdisk /dev/mmcblk0

WARNING: DOS-compatible mode is deprecated. It's stronglyrecommended to

switch off the mode (command 'c') and change display unitsto

sectors (command 'u').

Command (m for help): m

Command action

a toggle a bootable flag

b edit bsd disklabel

c toggle the dos compatibility flag

d delete a partition

l list known partition types

m print this menu

n add a new partition

o create a new empty DOS partitiontable

p print the partition table

q quit without saving changes

s create a new empty Sun disklabel

t change a partition's system id

u change display/entry units

v verify the partition table

w write table to disk and exit

x extra functionality (experts only)

先P，可以看到sd卡的现在分为4个区。

然后d，删除原分区，之后再n，创建新分区。

Command (m for help): d

Partition number (1-4): 1

Command (m for help): d

Partition number (1-4): 2

Warning: partition 2 has emptytype

Command (m for help): d

Partition number (1-4): 3

Command (m for help): d

Selected partition 4

删除分区之后再查看一下

Command (m for help): p

新建分区

Command (m for help): n

Command action

Last cylinder, +cylinders or +size{K,M,G} (1-62784, default62784):

（回车）

Using default value 62784

因为我只建立一个分区，所以在First cylinder (1-62784,default 1): 和Last cylinder, +cylinders or +size{K,M,G} (1-62784,default 62784):都不填写，直接回车

然后查看分区类型代码

Command (m for help): t

fat16为6,是我要的格式，所以Hex code (type L to list codes):后面填6,回车

最后保存分区表

Command (m for help): w

The partition table has been altered!

Calling ioctl() to re-read partition table.

WARNING: If you have created or modified any DOS 6.x

partitions, please see the fdisk manual page foradditional

information.

Syncing disks.

然后格式化分区

mkdosfs /dev/mmcblk0p1

完成~取出sd卡，再装进去，系统能够识别出来分区“2.1 GB SD 卡驱动器: 2.1 GB文件系统”，希望可以用了。。。

最后确定还是卡坏了~唉，这电信啊，送个kinston的卡，结果芯片厂商数据都读不出来，有点离谱了……
