DVD光盘内容拷贝时候的警告

jiangning

SUN E420R机器，DVD光驱，DVD光盘容量4G左右，执行如下命令：
cp /cdrom/* /export

产生警告：
Apr 30 12:17:54 v420 hsfs: NOTICE: hsfs: Warning: file system mounted on /cdrom/t9.2_3
Apr 30 12:17:54 v420 does not conform to the ISO-9660 specification:
Apr 30 12:17:54 v420 hsfs: file len greater than max allowed
Apr 30 12:17:54 v420 hsfs: Due to this error, the file system may not be correctly interpreted.
Apr 30 12:17:54 v420 hsfs: Other such errors in this file system will be silently ignored.

这样拷贝的CPIO文件有问题吗？应该用什么命令？
