我试图访问 exfat 格式的 Seagate 外置硬盘上的目录，但一直出现以下错误。在我的 Mac 电脑上，我可以毫无问题地访问目录并运行脚本，但当我在笔记本电脑上使用 Ubuntu 时，我开始遇到以下错误。到目前为止，我在笔记本电脑上访问这些目录时没有遇到任何问题，但从今天开始，我在访问某些目录时收到以下错误：
ls: reading directory '/Volumes/EEG000/eeg/data/2015/book_17/00002026_20151021/patient/reports': Input/output error
这种情况只发生在少数几个目录中，我还没能找出原因。我在 Mac 上访问这些目录没有问题。
dmesg似乎也没有报告任何与外部硬盘有关的可疑情况。以下是最后几行：

我已经安装并重新安装了 exFat-utils 和 exFat-fuse。
另外，这里是 fdisk 中与外部硬盘有关的最后几行：

我尝试在磁盘上运行fsck，结果发现一些容易出错的目录中的文件校验和不正确，于是修复了这个问题。我通过运行磁盘实用程序修复了 Mac 电脑上的损坏文件。
