i can not set permissions as root or as a user, so i can not make folders, copy files, etc. not even in terminal mkdir....

More details please. That's really not enough to go on.

Is this the primary hard drive or is it a secondary or external one? If it's the latter, check that it's mounted with read/write access.

Run the command cat /etc/mtab in a terminal and post the output here.

Try to copy a file to the target in a terminal and post the output of the command. The error messages may be helpful.

only one i can "yuse" is the file system main drive

I've never mounted an ntfs partition as type "ntfs", but always as type "ntfs-3g". I'd try that first.
