NTFS 其實就是window的一種file system.

NTFS is the standard file system of Windows NT, including its later versions Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008, Windows Vista, and Windows 7. Mac OS X v10.3 and later includes read-only support for NTFS-formatted partitions.

如果當你有external hardisk 是ntfs，那怎麼辦呢?

當然有solution~ 利用一套軟件 NTFS-3G，一套免費的，原自於linux 的軟體。

NTFS-3G is a freely and commercially available and supported read/write NTFS driver for Linux, FreeBSD, Mac OS X, NetBSD, Solaris, Haiku, and other operating systems. It provides safe and fast handling of the Windows XP, Windows Server 2003, Windows 2000, Windows Vista, Windows Server 2008 and Windows 7 file systems.

因為mac 是linux / unix? base 的，所以要移植一些opensource 的linux software 其實是不太困難的。

NTFS-3G 就要靠另一個opensource software Macfuse ，是google 其中一個programmer 寫出來的, Amit Singh。

之後就好簡單，只是install，restart 之後，mount drive ，就搞定了。Chowky 應該要用感思的態度去用這套software 呢~
