因此，我最近购买了一块小型开发板 (radxa)，与备用外部驱动器一起使用，以便创建 dropbox 克隆。起初我使用 Owncloud，但由于我的系统限制（32 位），php 无法处理超过 2gb 的文件，因此我切换到 seafile，因为我有很多超过 2gb 的文件。上传较小的文件（<1gb）一切顺利。尝试上传超过 1.5 gb 的文件时，情况发生了变化。
我的外置硬盘是普通的 1Tb 希捷硬盘，配有电源适配器，格式化为 EXT4。它设置为在启动时自动挂载（/dev/sda1 到 /media/ExtDrive），一切运行正常。
上传大文件时，我收到来自 seafile 的错误，提示无法读取数据位置（驱动器）。然后我使用 fdisk -l 检查它是否已安装，但似乎没有。我可以进入驱动器的文件夹，但出现权限错误，更改权限时出现文件系统只读错误。
重新启动时，PC 似乎崩溃了（无法通过 SSH 连接），需要断开 PC 和外部驱动器的电源线，然后一切似乎都正常，直到我重试上传大文件，然后同样的事情发生。有时我甚至需要在外部驱动器上运行 fsck，因为它已损坏。
可能是我的外部驱动器工作不正常或者是我尚未配置的设置？
多谢你们 ！

答案1
我可以通过拔下鼠标并将外部驱动器插入 USB 集线器来修复它。我不明白它为什么能工作，但至少它能工作！
