Please help me to set the full write supprot! the kernel don't support full write support !

dont do it. NTFS write support is not yet flawless.

NTFS write is not properly supported in the Linux kernel driver. You can try Captive-ntfs to get write support.

but if u still want to do then u need
to rebuild ur kernel
well i am a RH user
i can tell u with RH refrence
during recompiling ur kernel
use
make xconfig
it will open the options and as well load the old config.
then from there click filesystems
then find "support ntfs filesystem (Read only)"
when u click this option to make it compiled as module or
with kernel
another option with"ntfs support read/write (DANGEROUS)"
click it and then compile ur kernel

What's the simplest way to put this...

DONT ENABLE NTFS WRITE SUPPORT!

Enabling NTFS support can be done by rewriting the kernel, simply dont do it, it's not only flawed, writing to a mounted NTFS drive can cause permanent damage to your hard drive.

is the way to go!...here's a suggestion, make an extra vfat partition on your HDD and mount it under linux with the command beneath this, use it to transfer files between windows and linux.

to mount the hard drive:
mount -t vfat /dev/hda1

replace hda1 with the hard drive you wish to mount, replace vfat with the file system used.

Another suggestion: If you are moving smallish files and have a memory card reader use that as your intermediary for transferring files to Windows. NTFS read hasn't given me any problems besides the fact it forces me to be root to do it.. go figure.

You may want to try external application to enable ntfs write support.
