How to mount NTFS partition in FC6 on a RAID with ntfs-3g ?

[vhol]

I am running a PC with SATA RAID 0 and Fedora Core 6. I installed ntfs-3g.
I am having difficulties with mounting the NTFS partition that is placed on an extended partition on the RAID.
Obviously fdsik -l lists only physical drives so I can't mount /dev/sda3.

Anybody can help?

OK, found the answer. The trick was to mount the device found under /dev/mapper/... instead of the physical /dev/sda3
Following command did it:
ntfs-3g /dev/mapper/isw_cghfgghddh_ARRAYp3 /mnt/windata

I tried this too but it still doesn't work.
My fs structure is:

# fdisk /dev/mapper/nvidia_efegdffd -l

Disk /dev/mapper/nvidia_efegdffd: 320.0 GB, 320083591168 bytes
255 heads, 63 sectors/track, 38914 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

When I type:

# ntfs-3g /dev/mapper/nvidia_efegdffd6 /mnt/windows/

, I get this error message:

Error opening partition device: No such file or directory
Failed to startup volume: No such file or directory
Failed to mount '/dev/mapper/nvidia_efegdffd6': No such file or directory

Am I missing something?
