刚刚购买了 SanDisk microSDHC 8Gb 卡并尝试将文件系统更改为 ntfs（通过终端使用 cfdisk）。无法安装设备。尝试改回FAT32，还是无法挂载。运行： sudo mount /dev/mmcblk0p1 /mnt -t vfat 我得到这个结果：
mount: wrong filesystem, invalid option,
bad superblock in /dev/mmcblk0p1, ...
另外，dmesg 的日志：
[13891.357486] mmcblk0: p1
[13933.891942] mmcblk0: p1
[13974.716677] mmcblk0: p1 p2

[14157.995864] FAT-fs (mmcblk0p1): Can't find a valid FAT filesyste
节点看起来是金色的。 lsblk 给了我：
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 465,8G 0 disk
├─sda1 8:1 0 461,9G 0 part /
├─sda2 8:2 0 1K 0 part
└─sda5 8:5 0 3,9G 0 part [SWAP]
sr0 11:0 1 1024M 0 rom
mmcblk0 179:0 0 7,4G 0 disk
├─mmcblk0p1 179:1 0 7,5M 0 part
└─mmcblk0p2 179:2 0 7,4G 0 part
cfdisk 运行正常。此外，fdisk -l 不会返回任何内容。 （运行 Linux Mint 17）
关于如何安装有什么想法吗？
编辑：我使用sudo fdisk.当我插入时 dmesg 正在识别：
arthur@arthur-Aspire-5750 /sys/block $ dmesg | tail

[16314.439371] mmcblk0: p1
但是我仍然无法安装（同样错误的文件系统错误）。
答案1
mmcblk0 179:0 0 7,4G 0 disk
├─mmcblk0p1 179:1 0 7,5M 0 part
└─mmcblk0p2 179:2 0 7,4G 0 part
mmcblk0p1 只有 7.5 MB 大，您可能打算运行
sudo mount -t vfat /dev/mmcblk0p2 /mnt

请记住，使用 更改分区类型是不够的cfdisk，您还需要格式化分区。
