Name-error when formatting NTFS on OS X 10.8.4 using "diskutil" (Terminal)

I have a 2011 Macbook Pro 13 inch - OS X 10.8.4 (Mountain Lion), which i upgraded with a SSD. I installed the original HDD as second drive instead of the optical. I need to change the filesystem for volume (disk1s4) from HFS+ to NTFS. Paragon NTFS 10.0.2 driver is installed and activated. I just keep getting an error saying that the name is not a valid volume name for that file system. BTW: I also tried with Tuxera NTFS before installing Paragon.

Here is the Terminal log:

windows does not appear to be a valid volume name for its file system
******-Mac:~ ******$ diskutil eraseVolume NTFS "windows" disk1s4

******-Mac:~ ******$ 

EDIT:

Just to be clear. This is the volume i would like to format:

4:                  Apple_HFS Win7 boot               44.3 GB    disk1s4

EDIT 2:

I think I found a workaround-solution by searching google. In a thread (answer #3) in the tonymacx86 forum I found this line diskutil eraseVolume fat32 WINROOT /Volumes/WINROOT. I changed it to diskutil eraseVolume fat32 WIN7 disk1s4. It is now formatted as FAT32, which i think can be changed using the Windows 7 install disk.

Now it looks like this:

This is not possible using stock OS X since even on a normal drive (and not getting into any core storage considerations), diskutil does not support the UFSD_NTFS and NTFS formats:

Mac:~ bmike$ diskutil listFilesystems

These file system personalities can be used for erasing and partitioning.

You would need to use a tool other than diskutil to perform the formatting, but the Apple tools will respect and leave alone these volumes or make space for them by leaving free space or a FAT/ExFAT partition that you could then erase and leave NTFS data on the drive. Additionally, the Paragon pre-sales FAQ for 10.0.2 doesn't mention either Fustion Drive or Core Storage, so I would assume they don't support this. Have you asked them if core storage is supported?
