Ste*_*ton 2 disk ntfs io ntfs-3g
我有一个 NTFS 磁盘作为数据驱动器安装到 Ubuntu 系统 (19.10)。
在过去的几天里,驱动器变得非常缓慢且不可靠。
日志 (journalctl -r) 显示了这一点:

但是ntfsfix报告磁盘没问题(我认为)

在来自评论的建议中,一些smartctl输出。

我不知道如何准确解释它,但它看起来像一些加热问题?
建议更换驱动器。
Smart 05 表示使用多少备用扇区来替换坏扇区。RAW 值 9840 表示 9840 个扇区,也就是 4920KB。93 是标准化值意味着您仍有 93% 的备用分割线。
但是,同时 197 表示有 41344 个待处理扇区。待处理扇区并不一定意味着这些扇区是坏的,但硬盘驱动器未能完全处理它。(有时是因为在断电前没有刷新)在下一次写入时,它将返回到良好的扇区状态,或者转到 05 并被备用扇区替换。
不管怎样,41344 已经是 20MB 左右了。这已经太多了,意味着您的驱动器不稳定。
