我应该换SSD吗？

Demsg 显示了这一点

我也不能用磁盘做很多事情。简单的命令如

失败

如你所见，我每次重启都会检查

我的提供商说他做了一些 fchk，现在它又开始运行了。然而，这种情况已经发生过好几次了。每次发生这种事都会让我付出很大的代价。我想知道这是硬件还是软件？

答案1

您可能想使用smartctl它来访问聪明的在驱动器上。它有很多选项，其中一些是针对 SSD 的特殊选项，因此请阅读其手册页。一般来说，如果您的驱动器报告硬件错误，则需要备份（如果您还没有这样做）并更换它 - 今天的硬盘驱动器有足够的备用空间用于坏块重新分配，因此如果它报告问题，则很可能该缓冲区已被使用（或者驱动器出现其他问题）。但这并不一定意味着该驱动器没有其他用途（除了桌子的垫板之外）。

答案2

在大多数发行版上，您可以从命令行使用 fsck 立即进行磁盘检查 /sbin/fsck。例如：

% sudo /sbin/fsck -t ext4 /dev/sda1

警告：首先卸载文件系统！输入man fsck并阅读它以获取更多信息。

有时，这种检查看似可以通过驱动器创造奇迹，但不要屏住呼吸。这似乎是一个坏驱动器。根据我的经验，SSD 不太可靠。
