NTFS is not 100% supported. There is full read support, so copying from Win32 to Linux shouldn't be a problem but only partial, and experimental write support for NTFS. It could mess something up.
You're kernel must be compiled to use the NTFS file system. If it's not then you'll have to do so in order to do this.
