    3.2 Can the Driver write to an NTFS volume, too?

    Not really, but if you only need to copy files from Linux to Windows on
    a dual-boot machine, see "How to write to NTFS" below for a possible way
    to work around the lack of write support. For write support in Linux,
    read on.

    There are two drivers, currently. The original driver, in 2.4 has some
    write code in it, but it is extremely dangerous to use it. The
    possibility of destroying your filesystem is very high.

    The new driver, introduced in 2.5.11, has some write code, but it's very
    limited. The driver can overwrite existing files, but it cannot change
    the length, add new or delete existing files.

    Adding write support will take a long time. NTFS is built like a
    database. Any changes you make, necessitate making changes in many
    places, for consistancy. Make a mistake and the filesystem will be
    damaged, make too many mistakes and the filesystem will be destroyed.

    Paul.
