- Fix: The driver may returned “No space left on device” error when there was still free space on the NTFS volume.
- Fix: A file may got corrupted when the STANDARD INFORMATION attribute was moved to an extent MFT record. Only the already fixed Advanced NTFS-3G Driver had this problem, not the Stable NTFS-3G Driver.
- Change: 10-50% faster file and directory creation, removal, copy, unpackaging performance.

- Fix: Memory leaked if an extended attribute or alternate data stream couldn’t be opened.
- Fix: Report an error if a filename can not be listed during reading a directory.
- Change: The ‘locale=’ mount option is not used anymore for filename characterset conversion. Instead filenames are always converted to UTF-8.
TEST Version 1.5222-RC (December 22, 2008) — Release Notes
- New: Built-in, transparent UTF-8 conversion support.
- Fix: Report an error if a filename can not be listed during reading a directory.
- Change: The ‘locale=’ mount option is not used anymore for filename characterset conversion. Instead filenames are always converted to UTF-8.
- Fix: Reading a data storage with permanent or temporary physical damage, or a partial read(2) system call could result ignoring the low level hardware error and returning invalid data. Upgrade is recommended.
- Version 1.2926-RC is released unchanged as stable. The NTFS-3G driver is able for unlimited file and directory creation and removal as the result of 13 years continuous development with the help of hundreds of contributors over these years. Congratulations And Thank You To Everybody Who Made It Happen!
- New: Support unlimited file and directory creation. Successfully tested the creation of 54 million (54,000,000) files in a single directory, besides the other test cases.
- Fix: A corrupted directory index entry could hang the driver instead of returning “I/O error”.
- Fix: The allocation size of an attribute may got corrupted if the attribute size change failed.
- Fix: An MFT record could leak on big-endian CPUs if adding a new attribute failed.
- Fix: The system log was flooded if a transparently compressed or encrypted file was tried to be updated repeatedly.
- New: Solaris support.
- New: Libtool-2 support.
- Change: No external dependency on librt anymore when internal FUSE is used (default on Linux).
- Change: The default compiler is gcc.
- Change: Internal FUSE further shrank by 10%.
- Fix: A corrupted size directory or a directory over tens of million files may hang the driver. If NTFS-3G is compiled with an external FUSE library (non-default on Linux) then FUSE CVS is needed until FUSE 2.8.0 is released.
- Fix: Removing alternate data streams and extended attributes leaked memory.
- Fix: Mount could fail with some mount(8) utilities (e.g. busybox one) if the /etc/mtab file didn’t exist or was on a read-only file system. This fix should solve most of the “/bin/mount: invalid option -i” mount problems. If NTFS-3G is compiled with an external FUSE library (non-default on Linux) then FUSE CVS is needed until FUSE 2.8.0 is released.
- Fix: The driver always returned “I/O errors” if the standard file descriptors were closed during mount, e.g. via some usage of udev, hotplug, etc.
- Fix: Building the driver failed if the –prefix=/ configure option was used.
- Fix: Driver compilation may failed with ‘PATH_MAX undeclared’ error message in some (cross)-compilation environments.
- Fix: Mount failed with “Invalid argument” error message if the mountpoint was a symlink. If NTFS-3G is compiled with an external FUSE library (non-default on Linux) then FUSE CVS is needed until FUSE 2.8.0 is released.
- Fix: A corrupted directory could hang the driver.
- Fix: Mount could hang if the block allocation map was corrupted.
- Fix: The driver could hang or misbehave when compressed, sparse or encrypted file attribute flags were corrupted.
- Fix: The driver could crash when both an MFT attribute offset and the allocated bytes were corrupted.
- Fix: Building the driver failed if the –exec-prefix configure option was used without –sbindir=/sbin.
- Fix: Parallel ‘make install’ may failed.
- New: Support building the driver in a separate directory.
- New: Added –enable-mount-helper configure option which installs /sbin/mount.ntfs-3g, so mount via mount(8) and /etc/fstab can work on Linux. The default is enabled on Linux and disabled on all other operating systems.
- Fix: In certain, rare circumstances, any area of the NTFS volume, except the NTFS boot sector, could get corrupted. The chance for this to happen is higher for close to full disk utilisation and using one of the more uncommon, less than 4096 byte cluster sizes. The cluster size is logged under the /var/logs directory usually in the ‘messages’ or ‘daemon.log’ log file, as the blksize mount parameter. All stable releases have this issue since version 1.328. Upgrade is strongly recommended from all NTFS-3G releases.
- Fix: The total file system depth was limited to 4095 characters by FUSE and trying to access files and directories deeper gave “No such file or directory” error. If NTFS-3G is compiled with an external FUSE library (non-default on Linux), then FUSE CVS is needed until FUSE 2.8.0 is released.
- Fix: The symlink(2) system call failed or the size was truncated at modulo 256 if the old path was over 255 bytes.
- Fix: Unprivileged mount may have been denied because supplementary groups were dropped too early as a security measure.
- Fix: Unprivileged mount may have been denied if the /etc/fuse.conf file wasn’t properly configured. This was redundant and the /etc/fuse.conf file is not required anymore.
- Fix: Updating hard link attributes was delayed by one second which resulted softwares seeing their file sizes and timestamps incorrectly during this time interval.
- Fix: The ‘noatime’ mount option additionally and unconditionally was passed to FUSE.
- Fix: The driver crashed when one tried to open a non-existent file which had at least twice as long file name as the one allowed by the NTFS specification.
- Fix: Windows CHKDSK may reported minor inconsistencies because the data and allocation size of some special purpose resident unnamed $DATA attribute in the index and inode FILE_NAME attributes could be incorrect.
- Fix: Unprivileged mount failed if user had rights for everything except the FUSE device file.
- Fix: The ‘dev’ and ‘suid’ mount options didn’t work.
- Change: The rmdir(2) system call returns ENOTEMPTY instead of EEXIST because the GNOME glib library and the Nautilus file browser couldn’t handle the also standard EEXIST value which resulted an error message when for instance one tried to remove a directory containing files.
- Change: The ‘dev’ and ‘suid’ mount options are the default from now on for root mounts, similarly as other file systems behave. These options are always denied for setuid-root and unprivileged mounts.
- Fix: File and directory removal, rename and move may have been denied with an “Operation not supported” error message.
- Fix: Setuid-root ntfs-3g had a local root exploit and other security problems. From now on unprivileged mounts of block devices are possible only with using the integrated FUSE library (default on Linux) which has no known security problem.
- Fix: Unprivileged unmount didn’t always work.
- Fix: Create mount.ntfs-3g symlink always in /sbin where mount(8) needs it.
- New: Added ‘remove_hiberfile’ mount option to be able to read/write mount hibernated volumes for recovery and troubleshooting purposes.
- Change: Keep shrinking driver size.
- Version 1.2125-RC is released unchanged as stable.
- Fix: the 1.2121-RC test release didn’t compile on 64-bit architectures.
- New: Added ntfs-3g.probe utility which probes a volume for read-only or read-write mountability.
- New: To facilitate the use of the NTFS-3G driver in scripts, an exit code is returned to give an indication of the mountability status of the volume. Zero value means success, and all other ones mean an error. The unique error codes are documented in the ntfs-3g.probe manual page.
- New: Built-in FUSE support by using a stripped down, integrated FUSE library. Linux uses this by default which means NTFS-3G doesn’t require the installation of the FUSE package, only FUSE kernel support.
- New: The –with-fuse=external configure option makes NTFS-3G to be compiled with an external FUSE library. For non-Linux operating systems this is the default and the only compilation option.
- New: README file is installed as documentation.
- New: The –enable-ldscript configure option uses ldscript instead of .so symlink.
- New: Added libntfs-3g.pc.in pkg-config and libntfs-3g.script.so.in ldconfig files.
- Change: Rewritten, backwards compatible build system.
- Change: Use ‘make install-strip’ instead of ‘make strip’.
- Fix: The SIGTERM signal may caused deadlock which could block for instance the shutdown process. If NTFS-3G is used with an external FUSE library, which is not the default, then FUSE 2.7.2 package is required.
- Fix: Successful hard link removal may reported “Input/Output error”.
- Fix: Listing the content of a single directory having over 600,000 files and subdirectories may returned “Input/Output error” or truncated directory listing.
- Fix: The atime mount option didn’t work.
- Fix: POSIX file time updates (file access and modification times, inode change time). Please note, though NTFS-3G updates the times correctly now, FUSE may keep caching old, invalid time attributes for a short time after rename(2), creat(2), and some file operations which involve hard links. FUSE has fixed already the first two cases and they may be included in the Linux kernel 2.6.24 release.
- Change: 10-20% write performance improvement.
- New: relatime support was added and made the default file access time update method.
- Fix: Reads over the end of a file could return “invalid argument” error using recent kernels. This problem may have caused Thunderbird to hang.
- Fix: Some versions of the gcc compiler have crashed during compilation.
- Fix: The utimes(2) system call may incorrectly updated the last status change filestamp.
- Change: The ntfs.streams.list extended attribute enumerates Alternate Data Streams (ADS) ‘\0’ separated.
- Fix: big-endian problems exposed by the NTFS-3G Test Suite.
- Fix: free space calculation may was wrong for >1 TB volumes.
- Fix: some faulty Thunderbird versions caused system log flooding.
- Fix: uClibc and uClinux improvements.
- Fix: logging improvements.
- Fix: many other minor fixes.
- Fix: unwritten sparse file regions could get corrupted if the end of a write wasn’t aligned to cluster boundary. Sparse files are very rarely used, most typically by bittorent clients.
- Fix: creation of read-only files failed.
- Change: free inode calculation was CPU intensive during write activity. This could reduce write performance when millions of files are used if a file manager or desktop applet regularly polled for disk space usage. Now the statfs() system call is constant time.
- Change: file creation performance is improved by 40-80%.
- Change: smart directory traversal is 20-200% faster for disk based and 300-600% faster for memory cache based traversals.
- Fix: hibernation check was too rigid and mount was refused in read/write mode unnecessarily in some cases.
- Change: free disk space calculation was highly CPU intensive during write activity. This could reduce write performance severely, especially for huge volumes if a file manager or desktop applet regularly polled for disk space usage. Now the calculation is constant time, around only 10 microseconds on a typical desktop, and it’s completely independent of the volume size.
- All performance improvements are included unchanged from the 1.910-RC test release. Please see those details below.
- Change: significantly improved the performance of writing many files, typically by 50-1000% (copying files, unpacking, untarring packages, compilation, directory synchronization, …).
- Change: improved the performance of writing multi-GB size files, particularly after the creation of many thousands of other files. Previous disk space defragmentation is highly advised for the best possible speed. File level defragmentation is not enough.
- Change: improved concurrent write performance.
- Fix: utime() also updated the timestamp of the parent directory but it shouldn’t have (rsync, backup tool problems).
- Fix: ignore the “volume dirty” bit because its real meaning is “check the volume”. The fact of the real dirtiness is stored in the NTFS logfile which is already checked for.
- Fix: compilation failed with glibc 2.7.
- New: the –disable-library ‘configure’ option can be used not to install but link libntfs-3g into the ntfs-3g binary. This decreases the binary size by about 10-15% and increases performance by about 2-5%.
- Fix: file rename may updated the modification time of some files and directories which caused some backup tools, like rsync, not to preserve always this timestamp.
- Fix: unmount (fusermount -u) was denied for an unprivileged user who was allowed to mount a block device. FUSE 2.7.0+ user space package is required for the full fix.
- Fix: the driver could hang if there wasn’t enough memory during reading a large directory
- Fix: reading a directory may reported success when there was an error.
- Fix: metadata update error was ignored in some very rare cases during writing a file.
- Fix: permissions checking was turned on if umask, fmask and dmask was set to the default 000 value.
- Change: manual update, added Windows filename compatibility section.
- Change: lots of logging improvements.
- Fix: move, rename and hard link could return “input/output error”.

- Fix: default ownership of files weren’t always set to the mounting user.
- Fix: mount was denied if the NTFS Master File Table copy had non-standard size.
- Fix: catch and deny all junction/reparse point write operations.
- Fix: multiply -o options weren’t allowed (FreeBSD’s mount(8) requires this).
- Fix: don’t try to run Linux specific code on non-Linux OSes.
- Change: document and release version update to stable status.

- Fix: Mac OS X portability improvements.
- Change: full file permission checking if any of the uid, gid, umask, fmask, or dmask mount option is used.
- New: top request: setuid root support, the driver can run unprivileged.
- Fix: the ‘user’ and ‘users’ fstab mount options didn’t work (requires setuid root ntfs-3g).
- Fix: time of last file modification and status change weren’t updated.
- New: top request: support old FUSE kernel modules.
- Fix: ActiveSync didn’t work via Samba 3.0.
- Fix: writing large files could be very slow.
- Fix: writing several files at the same time could be very slow.
- Fix: writing at several places into a file at the same time could be very slow.
- Fix: invalid argument error when writing randomly into sparse files.
- Fix: heavy memory usage with sparse files (p2p, bittorrent client problems).
- Fix: inode number wasn’t filled in the dirent structures (CVS, getcwd, gnulib problems).
- Fix: 2-8% speed increase due to using pread/pwrite instead of lseek+read/write.
- Fix: fuse 2.6.x kernel module detection wasn’t reliable.
- Fix: directories were inaccessible on Windows if the cluster size was bigger than 4kB.
- Fix: static linking failed with FUSE 2.6.0.
- Fix: ‘make install’ failed if ldconfig wasn’t in the $PATH.
- Change: more verbose error reporting, explanations, hints for solutions.
- Fix: unmount was unsafe for removable devices.
- Fix: the code wasn’t endian safe.
- Fix: mount arguments were omitted on the 2nd fuse mount attempt.
- New: FUSE 2.6.0 is required to ensure maximum reliability.
- New: bmap() implemented: safe swap file support, LILO bootability.
- Change: the file system type is ‘fuseblk’ instead of ‘fuse’ for block devices.
- Fix: unmount was asynchronous; full fix requires FUSE 2.6.0 as well.
- Fix: mount was denied if $MFTMirr was too small.
- Fix: option parsing was incorrect if there was no space between name & argument.
- Change: new software versioning.
- Fix: file creation at disk-full may lead to i/o errors.
- Fix: statistic of inodes and free inodes was incorrect (df -i).
