NetBSD, Windows, and Linux each support both FAT and NTFS file systems.
Short for New technology File System, one of the file system for the Windows NT operating system (Windows NT also supports the FAT file system). NTFS has features to improve reliability, such as transaction logs to help recover from disk failures. To control access to files, you can set permissions for directories and/or individual files. NTFS files are not accessible from other operating systems such as DOS.
Windows makes use of the FAT and NTFS file systems.
System files are files necessary to boot an operating system. They do not necessarily exist on any given NTFS volume, and the choice of file system does not affect which system files are present.

If you are talking about accessing the partition from Linux, the kernel file system driver does not allow writing to NTFS partitions. You can write to the partition in Linux if you install the NTFS-3G file system. This is the only form of "write-protection" that should be on your system.
NTFS read support has been in the kernel since 2.2. 2.6.0 supports read / write operations.
Mac OS X cannot read an NTFS file system without the assistance of a third party program. See the related link below for a list of solutions if it is absolutely necessary to open NTFS file systems using OS X.
