Hello Dotan

Ubuntu can not write to NTFS with the standard NTFS driver. That's way you can 
not change the owner. The partition got mounted during boot by root.
Try option umask=000 instead of 007, or do
sudo umount /dev/hdb1
mount /dev/hdb1
Then you have mounted the partition as the running user and now the files should 
be owned by this user.
There is also a different for the mount option, "user" and "users" are not the 
same thing, but I can not remember the difference.
