我有一张 128 GB SD 卡，用于在我的 Lenovo Thinkpad X1 中永久存储。我已经用这一行将它安装在 /etc/fstab 中：
UUID=37733366-e936-41df-983a-f084352b3a5b /home/kristian/sd128gb auto defaults 0 0
这工作得很好。直到我把我的机器挂起，返回时我收到错误：
Error mounting system-managed device /dev/mmcblk0p1: Command-line
`mount "/home/kristian/sd128gb"' exited with non-zero exit status 32:
mount: File exists
挂载点目录为空，但尝试挂载它会给出
$ mount sd128gb/
mount: according to mtab, /dev/mmcblk0p1 is already mounted on /home/kristian/sd128gb
系统日志给出
