今天终于把这个问题搞定，记录下，网上那些文章说得不全，主要是给的网址下不了文件。在XP下安装APS很简单，直接安装就好。
在Ubuntu下就比较麻烦了，一直以来就想解决这个问题，在网上也搜了一些资料看，如：试着做了下，都不成功。
今天下了决心一定要把这个问题解决，就完全按照资料的顺序全部重新做一遍，一直到使用
$ sudo hdapsd -d sda -s 15 -a -v -y
来显示数据都是成功的，下一步
$ wget ~a0604095/hdapsd
这里就下载不了hdapsd这个文件，就通过下deb包，把hdapsd分离出来，并且需要两 个不同的hdapsd文件，一个位于/etc/init.d/，另一个位于/etc/default/（末尾附这两个 文件代码），然后，必须要执行$sudo /etc/init.d/hdapsd restart才能正常工作，不可能每次开机都去输入这条命令吧。
于是要使它开机自己运行，要把它放在/etc/rc2.d/下面，做一个软链接
$sudo ln -s /etc/init.d/hdapsd /etc/rc2.d/S99hdapsd
问题全部解决，开机自动工作，保护硬盘。
