我正在使用 Ubuntu 20.04 桌面版。我的 Seagate 硬盘通过 USB 3 端口连接到 Ubuntu 机器。我的笔记本电脑上总共有 3 个传统 USB 端口。在这三个端口上我都遇到了同样的问题 - 当将文件从主文件夹复制到 Seagate 时，速度从 145 MB/s 开始，然后在几秒钟内迅速降至 0 MB/s。它开始以高速复制文件，然后在速度接近零传输速度时迅速停止复制。
因此，我选择在这台 Ubuntu 机器上安装 samba 共享，并将我的主文件夹共享到我的本地网络。我能够从同一本地网络中的 Windows 笔记本电脑访问 Ubuntu 主文件夹，但当我尝试将文件从 ubuntu 传输或复制到 Windows 时，速度非常慢，大约 50 kb/s。复制大量数据需要很长时间。
我还尝试借用带有 USB C 端口选项的扩展坞来连接我的 ubuntu 机器。这个想法也失败了，因为速度一开始很高，然后很快就降到了零速文件传输。
我还尝试在 ubntu 主机中安装 vmware windows。我尝试从 vm 内部访问 seagate，但问题仍然相同。文件传输挂断并提示需要大硬盘，我猜这与 vm 的设置方式有关。
无论如何，我已经想不出如何将数据从这台 ubntu 机器备份到外部硬盘驱动器。请提供任何想法
谢谢
