NTFS is supported for OS X 10.6 and later versions.

By default, Mac OS can only read external mobile hard disks and USB flash drives in NTFS format. Only disks in the FAT32 or extfat format can be read and written.

Therefore, devices in NTFS format must use some special methods.

I have used ntfsmounter and found that it is not very easy to use. Paragon NTFS 10, very easy to use, but the price is too expensive.

But the disk cannot be identified in XP and Windows Server 2003.

Therefore, the macfuse solution is the most reliable, and the third-party software is easy to card the disk.

The following is an article I have found that I agree with it.

In Mac OS X, NTFS partitions can be read freely, but how to write is a common problem in many forums. I have seen a few good foreign posts recently. I will compile them for your reference.

0. Use the NTFS write function provided by Mac OS X

Requires Mac OS X to be later than 10.6

0. 0. Implementation Method 1: manually Mount partitions

This method is similar to the following method, but it is very troublesome to use the corresponding parameter Mount after manual umount.

0.1. Implementation Method 2: Modify the mount command to automatically mount partitions
[The following operations involve modifying the system. Please perform these operations with caution.]

Open the terminal:

Sudo mV/sbin/mount_ntfs/sbin/mount_ntfs.orig
Touch mount_ntfs

An empty mount_ntfs file will be generated in your home directory. Open it in a text editor. Enter the following content and save it.

#! /Bin/sh
/Sbin/mount_ntfs.orig-o rw "[email protected]"

Next, go back to the terminal you opened and execute it:

Sudo MV mount_ntfs/sbin/mount_ntfs
Sudo chown root: wheel/sbin/mount_ntfs
Sudo chmod 755/sbin/mount_ntfs

Now, your system will load the NTFS partition in read/write mode by default. In the future, if recovery is required, run the following command on the terminal:

Sudo mV/sbin/mount_ntfs.orig/sbin/mount_ntfs

0. 2. Method 3: Modify the/etc/fstab file to enable automatic mounting.

First, confirm that your NTFS partition has been mounted to the system. Open the terminal and execute:

Diskutil info/volumes/volume name

Here, the volume name is the NTFS partition name you want to mount. If you are not sure about it, you can enter Mount directly on the terminal and you will see the following:

/Dev/disk0s2 on/volumes/data (HFS, local, journaled)

The/volumes/data after "on" is your mount point, and the data is the partition name.

Well, let's get back to the point. Execute diskutil info and get the result similar to the following:

Device identifier: disk0s2
Device node:/dev/disk0s2
......
Smart status: verified
Volume UUID: B23CF4FE-EDBE-3E0A-8871-46078026CE40

Copy the content after the volume UUID, which is the unique ID of your partition.

Open/etc/fstab to edit the file. (If you have not done any other operations before, this file is not available by default ):

Sudo nano/etc/fstab

Enter the following in the file:

UUID = UUID of the NTFS partition none NTFS RW

If you have more than one NTFS partition, enter it in the branch. After editing, press Ctrl-X -- y -- enter to complete the editing.

At this time, the system will be automatically loaded after you restart the system.

0. 3. Implementation Method 4: Free Software ntfsmounter

Download ntfsmounter.com.

After the software is installed, a cat header appears on the top bar. When an NTFS partition is inserted, click the cat header to view the list of all partitions and click a partition, the system automatically reloads the selected partition in read/write mode, which is very convenient.

If you need to automatically load the software at startup, you also need to load the software in the system preference settings-account as the default program for boot.

0. 4. Notes

Any of the above methods basically use the read/write program that comes with Mac OS X.

In fact, Mac OS X comes with an open-source program. If you are interested in studying the source code, you can check it here.

The built-in program has some known problems:

If there are some inconsistent information in the NTFS partition, it cannot be loaded, that is, any of the above methods is still loaded in read-only mode.

This is because the default read/write program is only/sbin/mount_ntfs, and there is no newfs_ntfs (that is, the NTFS mode cannot be formatted), and there is no similar fsck tool. Solution: Mount your NTFS partition to windows for a disk repair. If it is USB, remember to exit safely.

Although it is native, Apple does not have Microsoft authorization or knowledge sharing, so this method is also dangerous and unstable.

On the Internet, some people may find that the actual file is lost, all the file icons are lost (that is, you can see an empty disk in the finder), and the copy file is lost.

If you encounter an inexplicable problem unfortunately, the first option is to fix the disk on Windows and exit safely.

1. Use third-party software

The common third-party software is as follows:



1.0. Paragon NTFS for Mac OS X

Currently, Paragon NTFS is the Latest Version 11.0 and is a commercial software.


According to its website introduction, it has developed a ufsd universal partition format that maps NTFS to this format (corresponding software maps HFS and other formats to this format on windows, to read and write Mac partitions on Windows ).

After installation, You can see several files under/sbin:

-R-XR-x 1 root wheel 44584 4 7/sbin/fsck_ufsd_ntfs
-R-XR-x 1 root wheel 61296 4 7/sbin/mount_ufsd_ntfs
-R-XR-x 1 root wheel 57860 4 7/sbin/newfs_ufsd_ntfs

We can see that it is relatively complete, not only mount, but also the corresponding fsck and newfs, that is, you can repair the partition yourself and create a new partition. After installation, there will be more paragon columns in the system preference settings, where you can choose whether to enable and which partitions to mount.

It is very easy to use.

In my personal use, we found that paragon is far less stable than propaganda.

Note that if you drag a file directly to the icon of a folder in the NTFS partition (that is, copy to the corresponding folder), the error probability is very high, in addition, you may not be able to find this file any more, as if it had entered a black hole. In addition, this problem also occurs when a large number of small files are copied at a time, and several will be lost.

For a large number of small files, the solution is to put them in a folder and drag the folder icon directly to the NTFS partition, which is much more stable. Of course, these are just my personal experiences, but they are only special cases.



1.1. macfuse + NTFS-3g

Macfuse, as I mentioned in my previous post, will be installed with VMWare Fusion in earlier versions; it and NTFS-3g are free software, no copyright concerns.

Considering the convenience of getting paragon in China, it is rarely used. According to feedback from foreign netizens, It is not stable. To achieve automatic loading, manual operations are required.

I will not go into details here. If you are interested, search by yourself. There are detailed tutorials in this regard.
