对比了一下自已的笔记本电脑，在Ubuntu Linux 下确实比 Windows 下响很多，当然Windows下读写数据时声音较之要小一点。
查了很多资料终于找到了一个命令 hdparm ，它可以设置很多和硬盘相关的参数，，硬盘响声也可以。
命令的说明如下：
Usage: hdparm [options] [device] ..
Options:-a get/set fs readahead-A get/set the drive look-ahead flag (0/1)-b get/set bus state (0 == off, 1 == on, 2 == tristate)-B set Advanced Power Management setting (1-255)-c get/set IDE 32-bit IO setting-C check drive power mode status-d get/set using_dma flag-D enable/disable drive defect management-E set cd/dvd drive speed-f flush buffer cache for device on exit-F flush drive write cache-g display drive geometry-h display terse usage information-H read temperature from drive (Hitachi only)-i display drive identification-I detailed/current information directly from drive-k get/set keep_settings_over_reset flag (0/1)-K set drive keep_features_over_reset flag (0/1)-L set drive doorlock (0/1) (removable harddisks only)-M get/set acoustic management (0-254, 128: quiet, 254: fast) “可以设置声音 🙁 ,linux 下居然这也能设置，如果只用windows 永远也不知道还有这回事啦 :-)-m get/set multiple sector count
. 省略………
sudo hdparm -M128 /dev/sda
设置后效果明显好转,其它参数有待于再研究了。
由此看来，这声音还有助于发现硬盘读写状况，和硬盘指示灯功能差不多了。

也有善意的提醒：何不去远方！昆明呀——赶一个花海;
