今天醒来后,我发现我的 ubuntu 家庭服务器的外部硬盘被关闭了,尽管正在进行应该使用硬盘进行下载的活动。
通过USB3.0连接,安装ntfs-3g。
这是我的 fstab:
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

以下是我认为包含相关信息的系统日志片段:

其余的是大量垃圾邮件条目,导致 ntfs_read 失败。
发生此事件后,我无法重新安装驱动器,因为它不再出现在 /dev/ 中。即使重新连接 USB 电缆也无济于事。设备的硬盘 LED 已关闭。我不得不重新启动机器才能使其再次工作。
问题是,这是什么原因造成的?我以后该如何避免这种情况?您需要任何其他信息吗?
