[tbam]

I searched the internet and got 4 answers.
first two commands has been test successfully indeed,however told

"dd: reading `/dev/cdrom': 输入/输出错误",
"cat: /dev/cdrom: 输入/输出错误".

I don't know why!

if the 3th 4th right?

代码： 全选

#dd if=/dev/cdrom of=/root/rh1.iso 	
#cat /dev/cdrom > /root/1.iso 
#cp -r /home/user name.iso
#mkisofs -a -l -J -L -r -o filename.iso /directory

1."dd: reading `/dev/cdrom': 输入/输出错误",
it means there is no such device on your pc named "/dev/cdrom" , try type "Tab" , or "/dev/cdrom0"

2.same error like above

my suggestion is try to understand what pc tring to tell you , not scared when showing some error (error is very common).

the 4th one , change "/directory" into "/dev/cdrom0"

wish u have a good time in Ubuntu , lol

有个叫mkisofs的工具，挺方便的。

我郁闷的是
明明他告诉我
输入输出错误
但还是成功的保存成iso了
（我的目的是把cd-rom的几张光盘保存成iso便于读取……）
