NTFS-3G is an open-sourcecross-platform implementation of the Microsoft WindowsNTFS file system with read-write support. NTFS-3G often uses the FUSEfile system interface, so it can run unmodified on many different operating systems. It is runnable on Linux, FreeBSD, NetBSD, OpenSolaris, illumos, BeOS, QNX, WinCE, Nucleus, VxWorks, Haiku,[1]MorphOS, Minix, macOS[2] and OpenBSD.[3][4] It is licensed under the GNU General Public License. It is a partial fork of ntfsprogs and is under active maintenance and development.
Sep 19, 2011 Base iso did not come with ntfs-3g installed by default. Same for Core Iso. On my Desktop in M/C shop running AntiX 11 Base. I used this thread mounting-usb-devices-in-rox-t3048.html for automounting usb drives in rox file manager also. After installing ntfs-3g. If me I would change some of the lines in your fstab to. Hi I got a similar problem. In my case (Ubuntu 12.04, using gparted and pysdm) I got a loading problem at start up, sdb2 was not able to mount at media/partitionName, where partitionName was the folder I set up with pysdm.In my case I was able to use and automount at.
NTFS-3G was introduced by one of the senior Linux NTFS developers, Szabolcs Szakacsits, in July 2006. The first stable version was released on 2007-02-21 as version 1.0. The developers of NTFS-3G later formed a company, Tuxera Inc., to further develop the code. NTFS-3G is now the free 'community edition',[1][failed verification] while Tuxera NTFS is the proprietary version.
May 11, 2014 客户有个电脑，装了linux系统，准备往电脑里拷文件，自己带过去移动一盘，插上一看，不识别。。。原因是当前linux系统不支持ntfs的分区。。网上查了下，幸亏有个小工具，叫ntfs-3g然后就从这里. 博文 来自： bubbleyang的博客. $ mount /mnt/ Unprivileged user can not mount NTFS block devices using the external FUSE library. Either mount the volume as root, or rebuild NTFS-3G with integrated FUSE support and make it setuid. Blog about Debian and other GNU/Linux distributions, configurations, scripsts, desktop environments and similar things.
Ntfs-3g /dev/sda1 /mnt/xp/ Unprivileged user can not mount NTFS block devices using the external FUSE library. Either mount the volume as root, or rebuild NTFS-3G with integrated FUSE support and make it setuid root. Please see more information at http://tuxera.com/community/ntfs-3g-faq/#unprivileged.
Features[edit]
NTFS-3G supports all operations for writing files: files of any size can be created, modified, renamed, moved, or deleted on NTFS partitions. Transparent compression is supported, as well as system-level encryption.[5] Support to modify access control lists and permissions is available.[6] NTFS partitions are mounted using the Filesystem in Userspace (FUSE) interface. NTFS-3G supports hard links, symbolic links, and junctions. With the help of NTFS reparse point plugins, it can be made to read chunk-deduplicated files, system-compressed files, and OneDrive files.[7] NTFS-3G provides complete support and translation of NTFS access control list (ACL) to POSIX ACL permissions. A 'usermap' utility is included to record the mapping from UIDs to Windows NT SIDs.
NTFS-3G supports partial NTFS journaling, so if an unexpected computer failure leaves the file system in an inconsistent state, the volume can be repaired. As of 2009, a volume having an unclean journal file is recovered and mounted by default. Scratch live old versions. The ‘norecover’ mount option can be used to disable this behavior.[8]

Performance[edit]
Benchmarks show that the driver's performance via FUSE is comparable to that of other filesystems' drivers in-kernel,[9] provided that the CPU is powerful enough. On embedded or old systems, the high processor usage can severely limit performance. Tuxera sells optimized versions of the driver that claims to have improved CPU utilization for embedded systems and MacOS.[10]
The slowness of NTFS-3G (and FUSE in general) on embedded systems is attributed to the frequent context switching associated with FUSE calls. Some open-source methods provided to reduce this overhead include:[11]
- The underlying FUSE layer has an option called
big_writes to use larger blocks when writing. Using a larger block means fewer context switches. This is in fact a solution recommended by Tuxera.[12] A patch is available to use an even larger block.[13] - There is also a Linux kernel option called
lazytime to reduce the writes on file access. - Synology Inc. uses a modified NTFS-3G on their NAS systems. It replaces the ntfs-3g inode caching
CACHE_NIDATA_SIZE with a different mechanism with unsure benefit. (It also includes an alternative Security Identifier translation for the NAS.)
History[edit]
- NTFS-3G forked from the Linux-NTFS project on October 31, 2006.
- On February 21, 2007, Szabolcs Szakacsits announced 'the release of the first open source, freely available, stable read/write NTFS driver, NTFS-3G 1.0.'
- On October 5, 2009, NTFS-3G for Mac was brought under the auspices of Tuxera Ltd. and a proprietary version called Tuxera NTFS for Mac was made available.[14]
- On April 12, 2011, it was announced that Ntfsprogs project was merged with NTFS-3G.[15]
- NTFS-3g added TRIM support in version 2015.3.14.

| Unprivileged user unable to mount using NTFS-3g As the subject states:
~> ntfs-3g /dev/ad0s1 winxp
mount_fusefs: /dev/fuse1 on /home/robert/winxp: Operation not permitted
fuse: failed to mount file system: Unknown error: 0
If I setuid in /usr/loca/bin/ntfs-3g
[robert@asus64] ~> sudo chmod 4755 /usr/local/bin/ntfs-3g
Password:
[robert@asus64] ~> ls -l /usr/local/bin/ntfs-3g
-rwsr-xr-x 1 root robert 29968 Feb 6 06:31 /usr/local/bin/ntfs-3g
then
[robert@asus64] ~> ntfs-3g /dev/ad0s1 winxp
Mount is denied because setuid and setgid root ntfs-3g is insecure with the
external FUSE library. Either remove the setuid/setgid bit from the binary
or rebuild NTFS-3G with integrated FUSE support and make it setuid root.
Please see more information at http://ntfs-3g.org/support.html#unprivileged
In /etc/rc.conf I have:
fusefs_enable='YES'
[robert@asus64] ~> kldstat
Id Refs Address Size Name
1 11 0xffffffff80100000 b6e000 kernel
2 1 0xffffffff80c6e000 205f8 geom_mirror.ko
3 1 0xffffffff80c8f000 230b0 snd_hda.ko
4 2 0xffffffff80cb3000 67458 sound.ko
5 1 0xffffffff80d1b000 4828 nfsmb.ko

7 1 0xffffffff80d23000 4fd8 atapicam.ko
8 1 0xffffffff80e22000 aa7a fuse.ko
How do I rebuild with integrated FUSE? It is not an option in the port.
[robert@asus64] ~> uname -a
FreeBSD asus64.shasta204.local 7.1-STABLE FreeBSD 7.1-STABLE #13: Fri Feb 6 14:43:48 PST 2009 root@asus64.shasta204.local:/usr/obj/usr/src/sys/GENERIC amd64
All ports were updated to the latest as of Friday.
Thanks in advance

| Re: Unprivileged user unable to mount using NTFS-3g I'm not sure if FUSE/FreeBSD supports block device based unprivileged mounts. Probably yes.
Please remove the relevant check from the source code and let us know how it works. If it will work for you fine then we will enable this in the next NTFS-3G version. Thank you.
| | Sun Feb 08, 2009 23:22 | Re: Unprivileged user unable to mount using NTFS-3g I have been searching but I can't seem to find the relevant code. It has been a long, long time since I have done any C coding. so a little help would be appreciated.
Thanks
Robert

| Re: Unprivileged user unable to mount using NTFS-3g It's in the src/ntfs-3g.c file at the beginning of the main() function. The main() function is at the end of the src/ntfs-3g.c.
| | Mon Feb 09, 2009 12:40 | Re: Unprivileged user unable to mount using NTFS-3g Thanks for that. I was not thinking too well yesterday. I did search for the file ntfs-3g.c but of course after cleaning a port it is no longer available.
In case you are not familiar with FreeBSD ports system, the 'make' will expand the *.tgz and place everything into a work directory. I commented out the #ifndef statement and rebuilt the port. (see below). I was then able to do an unprivileged mount after setting the setuid bit at /usr/local/bin/ntfs-3g.
I was unable to do an unprivileged umount. This is a minor annoyance but I thought that I should bring it to your attention.
Thanks again for your help.
Robert

| Re: Unprivileged user unable to mount using NTFS-3g For unprivileged unmount please try 'fusermount -u mountpoint'.
| | Mon Feb 09, 2009 19:08 | Re: Unprivileged user unable to mount using NTFS-3g I believe that fusermount is a linux only command.

| Re: Unprivileged user unable to mount using NTFS-3g In Debian the fusermount shows to be contained in the package fuse-utils. There is no such port or package available to FreeBSD.
As I stated before, it is a minor annoyance. I can use sudo to umount.
I want to again thank you for your help. ntfs-3g is now doing everything I really need it to do.

2) Has been achieved.
What parts of code should be modified/deleted in order to achieve 1) and 3)
Thanks in advance.
