安装软件时发现 无法 stat “./usr/share/man/man3”
于是我在终端打开看看，当运行下面时：
dpf@C1:/usr/share/man$ ls
cs fr.ISO8859-1 it man1 man6 pl.UTF-8 sv
de fr.UTF-8 it.ISO8859-1 man2 man7 pt_BR tr
es gl it.UTF-8 man3 man8 ru zh_CN
fi hu ja man4 pl ru.KOI8-R zh_TW
fr id ko man5 pl.ISO8859-2 ru.UTF-8
发现硬盘红灯亮，响声吱吱拉拉了一会才显示内容。

我又运行
dpf@C1:/usr/share/man$ ls -l

发现自己的man3是坏掉了。
于是想删除它
dpf@C1:/usr/share/man$ sudo rm man3
rm: 无法删除 “man3”: Permission denied
dpf@C1:/usr/share/man$ sudo chmod 777 man3
chmod: 无法访问 “man3”: Permission denied
可是出现了上面的结果，请高手们指点下怎么删除掉它，或者有没有什么更好的解决方法！
我万分感谢！
求求大伙了！
希望版主能帮帮俺！

响声吱吱拉拉,唉,不知UBUNTU对硬盘的读写采用的是什么技术,XP下硬盘灯再狂亮也不会听到这样的声音啊.
