我真的需要问这个问题,因为这对我来说非常令人沮丧整个星期。
我有一个 2 TB 外部硬盘 (Transcend 25H3),用于备份 Linux Mint 20 (Ulyana) 中的数据。我注意到文件传输速度非常慢(最大~1 MB/s),我首先将其归因于外部驱动器的性能。我已经将磁盘重新格式化为 NTFS 多次,但性能仍然相同。此外,磁盘需要很长时间(卡在旋转的圆圈中)才能通过Disks Utility
Mint 卸载/关闭。发生这种情况时,我尝试关闭计算机,但我被重定向到锁定屏幕。因此,我只是拔掉电缆,从而损坏了我chkdsk
在 Windows 10 中使用的修复文件。
然而,当我插入另一个外部驱动器(1 TB Seagate Backup Slim)时,我注意到性能和可拔出性方面也存在同样的问题(如果该词存在)。
使用umount
(even umount -f
) 也需要很长时间才能完成。我查看mount
并确认驱动器已不再安装,但ps aux
显示mount.ntfs
安装驱动器确实仍然处于状态Ds
。
当我在 Windows 中使用 Transcend 驱动器测试读写时,我获得了很快的传输速度(约 30 MB/s),并且卸载/安全删除也轻而易举。
话虽如此,这可能是一个可能的问题吗ntfs-3g
?或者,是 Linux Mint 磁盘/分区本身的问题吗?我正在运行双引导的 Windows (NTFS) 和 Linux Mint (ext4) 系统。

它是这么说的Device can operate at SuperSpeed (5Gbps)
,但让我担心的是它是这么说的Hub Port Status: Port [1-6]: 0000.02a0 lowspeed L1
。这是否是 USB 读写速度如此缓慢的限制因素?我尝试过使用 Linux Mint 和 Arch Linux 的实时启动,但两者也显示相同的集线器端口状态。

这是输出lsusb -t
