A few weeks ago we published a press release with Syabas about the integration of Tuxera NTFS into Syabas set-top boxes. Here’s a brief overview how everyone using Syabas products benefits from Tuxera NTFS inside. In the below pic you have Syabas’ Popcorn Hour set-top box at Tuxera labs ready to rock:

syabas_box

On the left you have two USB ports and on the right a removable hard drive bay circled. You can plug any NTFS-formatted portable hard drive or USB stick full of high-definition movies into the USB ports and it is plug & play. The same goes for the hard drive bay: take your NTFS-formatted drive from your Windows box and it works seamlessly with the Syabas media tank without any additional drivers.

We think Syabas’ example shows where the market is going. With both disk and file sizes growing, NTFS is currently the best — and in increasing cases the only — format option if you want your storage media to work plug & play with all computers from PCs to Macs and Linuxes as well as the latest consumer electronic devices.

For more information please see

http://macntfs-3g.blogspot.com/2010/06/ntfs-3g-for-mac-os-x-2010522.html

The latest release candidate of Tuxera NTFS for Mac, our high-performance commercial NTFS driver is out as well.

Changes since Tuxera NTFS for Mac 2010.1:

  • Extended attribute support. Tuxera NTFS for Mac now supports storing Mac streams such as Finder information and resource forks as extended attributes, translating to Alternate Data Streams in Windows terminology. This means that NTFS drives will no longer be littered with ‘._’ (AppleDouble) files. Services For Mac attributes are used for the special attributes ‘com.apple.FinderInfo’ and ‘com.apple.ResourceFork’.
  • Support for storing the Mac OS backup timestamp.
  • All new features, enhancements and fixes included in stable NTFS-3G for Mac 2010.5.22.

Tuxera NTFS for Mac gets more reviews

Following the latest release, Tuxera NTFS for Mac is receiving positive reviews all over the net. For example movie and television industry veteran David Roth Weiss has in mind a use case where large movie files are post-produced on a Mac and then submitted to clients who have PCs:

Until Tuxera, the 4Gb file size limitation made it impossible to copy files over 4Gb to a FAT32 formatted drive, and NTFS formatted drives could only be read on Macs, writing to them was not possible. … that could be a real deal breaker for many editors on Macs. Tuxera changes all that, and creates a seamless method for delivering files on hard drives to your PC-based clients.

Earlier also MacObserver picked Tuxera as the NTFS solution for Mac.

As a final note, Softpedia gave us “100% CLEAN” award :)

Release: Tuxera NTFS for Mac 2010.1

The latest release of Tuxera NTFS for Mac is now out!

Note: This release contains an important bugfix for the issue described in KB974729. All users are urged to update as soon as possible.

Changes since 2009.10:

  • A fix for the issue described in KB974729, in which NTFS drives were rendered unmountable in Windows Vista and Windows 7 in rare cases after being used extensively with Tuxera NTFS for Mac or NTFS-3G. After this update, Tuxera NTFS for Mac will no longer trigger this condition.
    To fix existing drives, please install the hotfix provided by Microsoft and follow instructions.
    If you have been affected by this issue and need assistance, don’t hesitate to contact our premium support email address (see your activation email).
  • Performance improvements: Tuxera NTFS for Mac now includes many of the improvements featured in Tuxera NTFS for Embedded systems, designed to further increase performance and reduce unnecessary driver workload, especially when working with many smaller files and traversing large directory hierarchies.
    For example, when crawling a test volume recursively, 2010.1 was nearly 40% faster than 2009.10 in our tests.
  • Performance improvements: The caching layer has been improved with more efficient lookup, which means less CPU overhead, and measures have been taken to minimize the amount of excess data that is read when accessing files in a random fashion.
  • Feature: Tuxera NTFS for Mac now includes a new preference pane option “Disable recovery dialog for hibernated volumes”, which makes the driver ignore NTFS volumes that contain a hibernated Windows session instead of showing a dialog asking the user whether it wants to purge the hibernated state or abort mounting.
  • Bugfix: Fix for some users of Snow Leopard who had problems with formatting NTFS volumes (Tuxera NTFS was not displayed as a formatting option at all times).
  • Fix: General usability improvements in the installer and preference pane.
  • Fix: Minor fixes to improve compatibility with the built-in NTFS driver.
  • Experimental: Tuxera NTFS for Mac now attempts to mount Windows LDM partitions by default. This will not work at all times, but one user did benefit from this change.

Release: NTFS-3G 2010.1.16

Happy New Year 2010 To All Tuxera Users!

The first open source NTFS-3G stable release of the year contains only important bug fixes:

  • Fix: Vista, Windows Server 2008 and Windows 7 couldn’t access a volume, file or directory if it had a non-resident TXF_DATA attribute despite being allowed by the NTFS $AttrDef attribute specification file. This scenario is very rare and hard to reproduce. Currently we have 1900 downloads a day and received only very a few such problem reports. Solution is also available from Microsoft. Please see more information at KB974729. Upgrade is recommended!
  • Fix: NTFS-3G may crashed if a junction point referred to a non-ASCII file.
  • Fix: Compilation errors on Mac OS X, OpenSolaris and openSUSE.

The source code of the latest stable driver is available at http://www.tuxera.com/community/ntfs-3g-download/

Many thanks to Microsoft, Jean-Pierre Andre, Erik Larsson, Anton Altaparmakov, Dominique Leuenberger, John G. Ireland, Virial, Elby, and Fuzzf.

We are happy to announce the next stable NTFS-3G release. It is based on the latest Advanced NTFS-3G release which is already used by several distributions as the default NTFS driver. The changes include:

  • New: Full file ownership and permissions support. The ownership and permissions of files are interoperable with Windows and conforms to the POSIX rules.
  • New: POSIX ACL support. The ACLs are an extension to ownership and permissions as defined in POSIX.
  • New: Optional Windows-type inheritance of ACLs.
  • New: Full extended attributes support for all namespaces: user, system, security and trusted.
  • New: Junction points support. The junction points and symbolic links created by Windows are seen as symbolic links.
  • New: Access is possible to NTFS internal data like Windows style archive bit and file attributes. They are mapped to extended attributes for easier access.
  • New: Compression write support: sequential writing to compressed files is supported.
  • New: Support copying and restoring encrypted files without decrypting them.
  • New: Support getting and setting high-resolution file timestamps.
  • New: Support to get, set and remove DOS filenames.
  • New: Tools for managing ownership, permissions and ACLs: secaudit checks the integrity of ownership, permissions and ACL, usermap gives help to configure ownership.
  • New: Implemented setchgtime() on Mac OS X.
  • Fix: Improved Windows junction and symlink handling.
  • Fix: Improved ACL handling.
  • Fix: Unicode normalization on Mac OS X.
  • Fix: Implemented true fsync() on Mac OS X
  • Change: Performance optimizations. Frequently used data are cached to improve speed. Space allocation for fragmented and sparse files has been improved.

We are also very glad to announce the new NTFS-3G lead developer, Jean-Pierre Andre who consistently demonstrated outstanding problem solving skills, taking great attention to the details and the ability to ensure the high-quality and reliability of the NTFS-3G driver in the past years.

Release: Tuxera NTFS for Mac

Erik Larsson

We are proud to present the Tuxera NTFS for Mac 2009.10 release!

Changes since version “1.0-RC”:

  • Preference pane internal classes were renamed to avoid a namespace collision with the NTFS-3G preference pane. If you had both NTFS-3G and Tuxera NTFS installed you could experience some strange behaviour in System Preferences.
  • Version number scheme changed to year.month[.revision].

Tuxera NTFS for Mac licenses can be purchased from the Tuxera Online Shop. As a customer, you are entitled to free updates. Your product key will continue to function in updated versions of the driver.

We also have a dedicated customer support email address where you can reach us and get help with the product, or get feedback on any problems that you may have.

Technical briefing

We were asked for a technical write-up regarding the changes that have been made to the NTFS driver for Tuxera NTFS for Mac, so I’m going to make an attempt to describe what we have done.

The most important issue that we identified when studying how to build a commercial grade product from the existing NTFS-3G for Mac OS X product was that performance still wasn’t optimal. This has been a problem for NTFS-3G from day one, caused by inefficient kernel/userspace interfaces to the raw disk devices provided by the Mac OS X kernel. Even after applying relevant patches to supply a caching layer between the disk device and the file system driver, we never fully reached the performance level that we would have desired.

Also, the existing caching layer (originally from the FreeBSD port of NTFS-3G) introduced a new problem: written data could stay in memory for long periods of time without being flushed to disk. This means that if the Mac would run out of battery, encounter a system crash, or if someone would disconnect an external drive without unmounting it first, then the latest changes to the data on the NTFS drive would not have reached the disk. The result in this situation is that people would lose the latest data that was written to the NTFS volume. Volume inconsistencies needing to be fixed with ‘chkdsk’ in Windows would also be very likely.

Essentially with NTFS-3G, people were forced to choose between better performance (caching on) and keeping the data safe in the event of a system crash (caching off).

We eventually decided to write a new caching layer from scratch, partially to be able to experiment with performance and to squeeze the best performance out of the disk, but also to be able to incorporate smart cache flushing to ensure that data doesn’t stay in memory longer than it absolutely needs to.

This proved to be very successful. With the new caching layer we have in many cases recorded performance comparable to and in some cases even better than the built in HFS+ driver.

Additional improvements have been made. Some examples:

  • Implemented support for the Mac OS X “Locked’ and “Hidden” features for files, mapped to their NTFS equivalents (readonly, hidden). This can be used to make files immutable by “locking” them, just like on HFS+ volumes.
  • Adaptive file ownership: The files on an NTFS volume always appear to be owned by the user currently accessing it.
  • Support for putting files in the ‘Trash’ bin (in NTFS-3G, you could only delete them directly).
  • Some bug fixes that will eventually appear in NTFS-3G as well, for instance: Firefox wouldn’t save files on an NTFS volume, International (non-ASCII) volume names led to an error when mounting…

We have also reconstructed the preference pane, added help content, and in many other ways made sure to iron out the small quirks and irregularities encountered in NTFS-3G, to make sure that we deliver a polished, tested and well-functioning product for the commercial market.

Mac OS X comes with an NTFS driver but it does not support writing to NTFS volumes out-of-the box. The fix is here. We are pleased to announce the immediate availability of Tuxera NTFS for Mac Trial. You can download it here. Please note that this is a release candidate version and the final one will be available before the 15-day trial period is over.

system_preferences
After installation, Tuxera NTFS becomes visible in your System Preferences.

tuxera_mac_screenshot
There are many options you can play with. See the manual for explanations.

This is a release candidate version and a major upgrade from our previous open source NTFS-3G for Mac. Performance has been significantly improved along with other enhancements. We are pretty sure this is the fastest read/write NTFS driver you can have for Mac. We have successfully tested it on Tiger, Leopard and Snow Leopard. Please send us any issues you find and we will fix them before the final release is out and available for purchase.

It has been an interesting week. Our Microsoft PR went through the media pretty much as expected. Some coverage:

Brief answers to frequently asked questions so far:

  • The agreements do not allow us to distribute end-user or open source exFAT drivers for Linux. We are communicating with Microsoft and hope to do that in the near future. A solution is needed before exFAT becomes a de facto standard.
  • The agreements do not change anything regarding NTFS drivers. We will continue to distribute and support NTFS-3G both under GPL and commercial licenses.
