COMRESET失败(errno=-16)
COMRESET失败(errno=-16)
提问于 2017-12-23 10:49:45
有时，当我打开我的笔记本电脑，第二硬盘没有挂载。启动时间也很长。如果我关闭它并重新启动，它可能会工作。我发现了下面的错误，但我不知道如何修复它。我使用Ubuntu16.04.3 LTS。硬盘是希捷ST2000LM007 2TB SATA硬盘驱动器安装在惠普Omen。

启动从现场媒体，看看你是否有相同的问题。如果不是，它指向一个软件问题，如果是这样，您有一个硬件问题继续读。
识别您的模型并检查系统板与硬盘的连接。如果它是电缆，更换它，如果没有，确保插座没有松动的主板和驱动器是正确的位置。如果可能的话，在另一个具有已知良好连接的系统中测试驱动器，以确定问题是否遵循驱动器，如果是这样，则替换它。如果对这个答案有什么不清楚的地方，请给我一个评论，我会尽力澄清的。
