Ubuntu / Mint上的Linux USB问题

经过一些更新（4.4.0内核，Linux Mint 18）后，我意识到旧的USB记忆棒在新的高速USB记忆棒时遇到了麻烦，例如： 32GB运行良好。

使用我的一个旧USB记忆棒（格式：fat32），例如2GB，4GB造成问题。在大于1GB的文件的复制过程中，nemo挂起，百分比保持在例如85％，我无法打断或阻止它。如果我杀了这个过程，僵尸进程仍然存在。

奇怪的是，复制在Linux中总是最好的。现在有些东西坏了，我想原因可能是USB3.0的支持。我读过很多关于USB3.0的坏评论。

现在复制已经成为一个可能有效的过程。这让我发疯了。 我已经仔细检查了USB记忆棒，问题肯定是软件，而不是硬件损坏。

有人知道真正的原因吗？
