Check that you have write access to this file or that enough disk space is available.
even when I try putting rw switch
chmod 777cdrom2.loop does not work even as root
I am not sure to understand what this relates to...
A little bit of context and feedback on my previous answers will be apreciated.

If the cdrom2.loop partition device is not NTFS and you got write access granted
to the partition using the mount -f -o remount,rw ... it shoudl work....
