经过一些更新（4.4.0 内核，Linux Mint 18）后，我发现旧的 USB 记忆棒出现了问题，而新的高速 USB 记忆棒（例如 32GB）却运行良好。
使用我的一个较旧的 USB 记忆棒（格式：fat32），例如 2GB、4GB，会出现问题。在复制大于 1GB 的文件的过程中，nemo 会挂起，百分比保持在例如 85%，我无法中断或停止它。如果我终止该进程，僵尸进程仍然存在。
奇怪的是，在 Linux 中复制总是效果最好。现在有些东西坏了，我猜原因可能是 USB3.0 支持。我读过很多关于 USB3.0 的负面评论。
现在复制已经变成了一个可能成功也可能失败的过程。这让我抓狂。我仔细检查了 USB 驱动器，问题肯定出在软件上，而不是硬件损坏。
有人知道真正的原因吗？
