我正在运行 Ubuntu 12.04，似乎我的 SSD 出现故障。经过任意时间后，end_request i/o error, dev sdc sector xxx当我输入命令（例如ls或其他任何命令）时，磁盘才会打印。这种情况可能发生在 24 小时后或几分钟后。
所有的 SMART 测试（短/扩展）都通过了，并且没有重新分配的扇区，尽管我不确定 SSD 是否像旧的磁性类型那样处理它。
程序失败计数似乎是 SMART 日志中最突出的问题。4745980543444 次失败？这差不多有 5 万亿了吧？
与普通硬盘驱动器相比，我能做什么特别不同的事情吗？

看起来这更像是一个糟糕的固件，而不是什么太严重的问题。参见：
以下是相关内容：
该驱动器可能在通电 5184 小时后挂起：

请参阅以下网页以了解固件更新：

您最近已超过 5184，因此这看起来更加相关。
无论哪种方式，请备份并准备将其转移到另一个磁盘上。
