1)As I said to you before, NTFS support under linux is read-only at best. This means you can read whatever is on it, but you can not write files to it. So no, you cannot write to it.

Due to the uncertain legal status of using the NTFS driver, RedHat and Fedora have chosen to leave the driver out of their kernels.
Please read the documentation.
As indicated on that page, here is the link to the ntfs rpm's.
