-p当帮助中说选项无效时,为什么选项无效Automatic repair (no questions)?那么我该如何修复我的 SD 卡呢?

查看两种情况下输出的第二行。fsck --help使用fsck.ext3(系统上的默认设置)并显示对该工具有效的选项,但fsck -p /dev/mmcblk0使用exfatfsck它是因为这适合您的 SD 卡。

很遗憾exfatfsck 无法修复错误,它只能报告它们。所以跑

fsck /dev/mmcblk0

查看是否有任何错误;如果有,您将需要一些其他策略来修复文件系统:

  • 使用另一个带有能够修复文件系统的工具的操作系统(Windows?);
  • 或者在 Linux 上,将所有文件复制到其他位置并重新格式化卡。
