can't see file system after mounting in Debian

#mount -t iso9660 /dev/hda /media/cdrom
mount: block device /dev/hda is write-protected, mounting read-only

#cd /media/cdrom
autorun.inf udfrinst.exe

chmod 666 /dev/hda .The device 'hda' user is 'root 'and group is 'cdrom'. That is why I decided
to give rw priviliges to all.

#umount /dev/hda /media/cdrom
device busy (I can't unmount until restarting the computer). I tried giving a symlink 'ln -sf /dev/hda /dev/cdrom which is most likely unecessary.
My USB flash device mounts with no problem and all the files are seen. The DVDrom drive with cdrom disk seems to mount but can't see any files.

I would appreciate some help

This CD was either created by Roxio DirectCD or Nero InCD. These CDs use the udf instead of the iso9660 filesystem. Those files you see are drivers that windows will automatically load if the system your using does not have them already installed.

mount -t udf /dev/hda /media/cdrom

Not sure if udf is included in a default debian install.

When you umount make sure that nothing is accessing the CD including the shell. Just cd somewhere else.

I mounted a debian #5 disk and that mounts with files seen.
You are absolutely correct. I formated the problematic cd using the udf (roxio windows program) and that was the issue of my not seeing the files.
I will try your suggestions in regards to udf.
Thanks very much
