Tuxera NTFS for Mac / NTFS-3G doesn't mount the drive, even though I installed it correctly.Q:
My NTFS drive is still read only, even after installing Tuxera NTFS for Mac / NTFS-3G.Q:
I'm unable to access my NTFS drive after installing Tuxera NTFS for Mac / NTFS-3G.Q:
"It doesn't work!"A:
The most common reason why NTFS-3G or Tuxera NTFS for Mac doesn't mount an NTFS volume is that it contains errors or inconsistencies. These problems can occur if you detach a hard drive from a computer without unmounting it first ("Safe remove hardware" in Windows, the eject button next to the volume in Mac OS X). They can also occur if your operating system crashes, or if your computer otherwise shuts down abnormally.
To recover from this situation, attach the drive to a Windows computer and run 'chkdsk /f' on the drive to repair any problems in its internal structures. See http://support.microsoft.com/kb/315265
for usage information regarding 'chkdsk'.Q:
I'm getting error -36 when copying file to the NTFS volume in Finder. Why, and how can I fix it?A:
Error -36 is a very general error and can mean lots of different things. Here are the most common causes of error -36:
- You are trying to explicitly copy AppleDouble files (starting with '._') to the NTFS volume. These files have a special meaning as bearers of Apple-specific metadata on non-Apple filesystems, and they shouldn't exist on Apple-provided file systems. There's a solution to this problem in the following thread: http://www.tuxera.com/forum/viewtopic.php?f=4&t=3300
- Some of the filenames that you're trying to copy are too large to be copied to the NTFS volume. This can sometimes happen with filenames with 200+ characters that contain "international" characters (i.e. characters that lie outside the normal US/English character set).
- Your drive has internal inconsistency issues. In this case you should get error messages in your system.log file. This problem is fixed by running 'chkdsk' in Windows as described above.
- Your drive has bad sectors. This should normally also trigger error messages in system.log. 'chkdsk' in Windows is often able to discover and mark these bad sectors if you supply the '/r' parameter.
If you have bad sectors on your hard drive, you should rescue your data and replace your drive as soon as possible.
Why does all NTFS drives disappear from the "Startup Disk" preference pane after installing Tuxera NTFS for Mac / NTFS-3G?A:
Apple does not allow any volumes that are mounted with third party file system drivers to appear in the "Startup Disk" preference pane. This is hard coded, and something that we cannot change.
However, there are numerous alternative methods for booting into Windows:
- Hold down the Option key during boot (or Alt for non-Apple keyboards).
This brings up a boot menu where you can choose which volume to start your computer from.
- Install the rEFIt boot manager for better control of the boot process.
- Disable Tuxera NTFS for Mac / NTFS-3G (using the preference pane), unmount your NTFS volume with Disk Utility and mount it again.
Your volume will now be mounted with Apple's read-only NTFS driver, and the "Startup Disk" preference pane will behave as usual. Make sure to reenable Tuxera NTFS for Mac / NTFS-3G afterwards.
- Use the command line utility bless to set the disk that should be used as default startup disk (see man bless for more information).
Does Tuxera NTFS for Mac work with TrueCrypt, VMware Fusion, Parallels Desktop, ... ?A:
Yes, all of the above have been tested to some extent. If you encounter a situation where it does not work for you, then it's a bug and should be reported to us, via email or a forum post describing the problem.Q:
How do I create a metadata image of my NTFS volume that I can send to the developers to aid in troubleshooting?A:
We have written a special application for this purpose which can be downloaded here: http://www.tuxera.com/mac/ntfsmetaclone-1.1.dmgUpdated 2009-12-31 (version 1.1): Improved Snow Leopard support and fixes for temporary GUI lockup bugs when extracting.
- Download and open the disk image (see above).
- Start the application by double clicking the icon "Extract NTFS metadata" inside the attached disk image.
- Select the device that your NTFS volume resides on (you can look this up in Disk Utility's "Info" window).
- Make sure that the volume that you're trying to extract metadata from is not mounted (i.e. unmount it in Disk Utility).
- Press the "Extract metadata" button.
- Specify an output filename in the following save file dialog.
- Authenticate as an administrator to allow the metadata cloning utility to gain access to the disk device.
Now the program will start cloning the device metadata to the specified file.
