双系统问题，如何能互相访问？

安装ntfs-3g.这玩意很成熟了
然后挂上去就K.O.了
ntfs-3g is an NTFS driver, which can create, remove, rename, move
files, directories, hard links, and streams; it can read and write
files, including streams and sparse files; it can handle special files
like symbolic links, devices, and FIFOs; moreover it can also read com-
pressed files.

EXAMPLES
Mount /dev/hda1 to /mnt/windows:

ntfs-3g /dev/hda1 /mnt/windows

or

mount -t ntfs-3g /dev/hda1 /mnt/windows

Read-only mount /dev/hda5 to /home/user/mnt and make user with uid 1000
to be the owner of all files:

ntfs-3g /dev/hda5 /home/user/mnt -o ro,uid=1000

/etc/fstab entry for the above:

/dev/hda5 /home/user/mnt ntfs-3g ro,uid=1000 0 0

Unmount /mnt/windows:
