我通过 USB2 使用这个带有 Ubuntu 11.10 的外壳： http://www.newegg.com/Product/Product.aspx?Item=N82E16817173042
一段时间不活动后，机箱似乎进入睡眠状态，Ubuntu 无法将其唤醒。我已确认内部驱动器正在工作（没有坏块等）。此外，在 Windows 中，当机箱处于睡眠状态时，Windows 似乎能够在访问驱动器时将其唤醒。在 Ubuntu 中，我只有在访问挂载点时才会收到 I/O 错误。
syslog 的相关部分如下所示。有人能告诉我这是否证实了我上面的想法吗？我该怎么办？

答案1
首先，抱歉我的回复这么慢。
考虑使用cron和touch唤醒磁盘。这将每分钟唤醒一次磁盘。
在终端中运行，crontab -e
现在，nano如果它提示编辑器，请选择。
在文件末尾的新行添加：
*/1 * * * * touch /media/usbdisk/touch.txt
按Ctrl+ O（即字母 O），然后Ctrl按 + X。如果语法正确，命令应该会成功。请将其替换/media/usbdisk/为 HDD 的挂载点。
