我插入 1TB 可移动硬盘,Ubuntu 将其挂载。我开始提取 45GB 的 7z 压缩照片,一段时间后(大约 10 分钟),硬盘卸载,提取失败。
我怎样才能停止驱动器卸载?
我读了一些得出这个结论的帖子,然后卸载了 laptop-mode-tools,但这并没有帮助。
dmesg 提供此输出。

我的 fstab 非常简单
# /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).

我已将其添加到 fstab 中,以便始终以相同的方式挂载它。

dmesg | tail 提供此功能。
sayth:~$ dmesg | tail

而且 fsck 也帮不上忙,我真的没有主意了。
sayth:~$ fsck /dev/sdb1
fsck from util-linux 2.20.1
fsck: fsck.ntfs: not found
fsck: error 2 while executing fsck.ntfs for /dev/sdb1
答案1
听起来你的驱动器已损坏:
[ 372.444424] end_request: I/O error, dev sdb, sector 250589039
您可以尝试以下操作:
将驱动器连接到 Windows 计算机并在那里运行检查磁盘。在 Windows 下,NTFS 检查可能更好(这是假设)。
运行
ntfsck
。在 Debian 系统上,/sbin/fsck.ntfs
是 的符号链接/bin/ntfsfix
,但在 Ubuntu 上似乎并非如此。因此,您需要ntfsck
手动运行。这应该已经安装,但如果没有,请使用 进行安装sudo apt-get install ntfs-3g
。然后运行sudo ntfsfix /dev/sdb1
用于
smartctl
显示驱动器的 SMART 状态:sudo smartctl /dev/sdb
这虽然不能解决任何问题但可能有助于调试问题。
