Windows 7 partition (drive) don't showing up on Snow Leopard Build 10A432 64bit mode

I found this:

• How to check Whether your Mac has the 32-bit EFI or 64-bit EFI :
When you are reading this i m sure you understand that you can boot into full 64bit mode if your Mac has 64-bit EFI. Also note that Apple disabled 64-bit kernel support for any Macbooks, even with 64-bit EFI. So if you have an older Mac Pro, iMac and you wants to check Whether your Mac has the 32-bit EFI or 64-bit EFI just enter the following command in Terminal.

ioreg -l -p IODeviceTree | grep firmware-abi

And you’ll get the answer either “EFI32″ or “EFI64.”
• How to boot 64-bit Kernel by default at every boot : Though you have a EFI64 and 64-bit compatible Mac your install will boot into 32-bit kernel by default. Thanx to Netkas for highlighting a trick to change default boot kernel. All you have to do is edit a string file in com.apple.Boot.plist To edit boot.plist navigate to /Library/Preferences/SystemConfiguration/com.apple.Boot.plist and open the boot.plist with text editor and find the following string.

<key>Kernel Flags
</key><string></string>

and change it to

<key>Kernel Flags</key>

<string>arch=x86_64</string>

That’s it, now your installation will boot in to 64-bit kernel mode every time. So no more holding down the ‘6′ and ‘4′ keys during boot. Just in case if you need to boot the 32-bit kernel just hold down the ‘3′ and ‘2′ keys during boot.

------------------------------------------
Check if you running in 32 or 64 bits kernel mode:

open Terminal and type "uname -a" (without quotes). It should return something that ends in either i386 (32-bit) or x86_64 (64 bit)

My Mac has 64-bit EFI

It works like a charm accept: everytime i boot into Snow Leopard "64-bit kernel" my Windows 7 partition (drive) don't showing up (no problem on the 32 bit-kernel), how can i solve this?

Anyone?????

Thanks in advance.

 

Thanks for your comment. Found it! I disabled my NTFS-3G prefpane (32-bit), for write permissions on my Windows 7 volume, and it's activated. Searching for another option to get write permissions on my Windows 7 Volume.
