无论是否不活动，都要保持外部硬盘运行

在闲置约一个小时后，我的希捷3TB硬盘变得无法访问程序（例如Deluge）。在启动任何与文件/目录相关的任务的那一刻，nautilus会提示我一个显示该驱动器内容的窗口，但是当驱动器被视为非活动状态时，其他程序（取决于存储空间）已被预先中断。 无论用户活动如何，有没有办法让硬盘保持运行？

如果所有其他方法都失败了，您可以每隔59分钟执行一次cronjob，在硬盘上复制最小大小的文件，从而创建磁盘活动。

我可能会试试。

-S     Put the drive into idle (low-power) mode, and also set the standby (spindown) timeout for  the  drive.   This  timeout
          value  is used by the drive to determine how long to wait (with no disk activity) before turning off the spindle motor
          to save power.  Under such circumstances, the drive may take as long as 30 seconds to respond  to  a  subsequent  disk
          access, though most drives are much quicker.  The encoding of the timeout value is somewhat peculiar.  A value of zero
          means "timeouts are disabled": the device will not automatically enter standby mode.  Values from  1  to  240  specify
          multiples  of  5 seconds, yielding timeouts from 5 seconds to 20 minutes.  Values from 241 to 251 specify from 1 to 11
          units of 30 minutes, yielding timeouts from 30 minutes to 5.5 hours.  A value of 252 signifies a timeout  of  21  min‐
          utes.  A value of 253 sets a vendor-defined timeout period between 8 and 12 hours, and the value 254 is reserved.  255
          is interpreted as 21 minutes plus 15 seconds.  Note that some older drives may have very different interpretations  of
          these values.
