    i was wondering if anybody has been able to get ntfs support working for lion. i have an external drive that's formatted in either FAT or NTFS and when i plugged it in an error popped up saying it couldn't be mounted.

    anyone else having this problem?

    Don't know if this helps but, when i insert my FAT32 usb key it mounts and works, read/write.

    I can also access my bootcamp NTFS partition, but it won't write, so i don't think NTFS support is working ;)

    NTFS volumes do mount under Lion without any problems for me, but they are read-only (for the moment at least)

    I thought Apple might include native read/write support, but I had trouble getting it to mount in read/write mode when doing it manually.


    /sbin/mount_ntfs -o rw /dev/disk2s1 /volumes/ntfstest

    I use Tuxera NTFS. It has 64 bit kernel support and is working well so far.

    NTFS (Windows NT File System)
    • Read/Write NTFS from native Windows.
    • Read only NTFS from native Mac OS X
    • To Read/Write/Format NTFS from Mac OS X: Install NTFS-3G for Mac OS X (free)
    • Some have reported problems using Tuxera (approx 33USD).
    • Native NTFS support can be enabled in Snow Leopard, but is not advisable, due to instability. Time will tell if this instability is corrected in Lion.
    • AirPort Extreme (802.11n) and Time Capsule do not support NTFS
    • Maximum file size: 16 TB
    • Maximum volume size: 256TB

    Why not use a USB flash memory thumb drive to clone the image onto and use that to do a clean install of Mac OS X 10.7 Lion?

    I have an interesting scenereo for you.. I have bootcamp installed so I can dual boot win7 and Lion. When I installed w7 I formatted in NTFS, now that I have upgraded to LION it does not recognize the partition, it complains, and VMWare no longer will connect / recognize that bootcamp.

    I am stumped, does anyone have any suggestions?

    I was hoping that they would have support for NTFS in Lion. But it is the same as what it was in SnowLeopard; read only. I had previously used NTFS-3G but was holding out buying the Tuxera software until Lion but now it looks like I'll have to bite the bullet and buy Tuxera.

    I had serious problem with that method, so I dumped it fairly quickly some time ago.
    I also had problems with NTFS-3G. It was flaky, and I can't afford that with valuable data.
    I then bought Paragon NTFS, and it has been 100% reliable since the day it was installed.

    And what about Lion ?
    Does it support NTFS read/write natively ?

    So bottom line, which plug in is the best to read NTFS external hard drives with Lion? I used to have one that worked perfectly for snow leopard but now that i have Lion is just not working!

    As I said above, I (and others) have had some issues with NTFS-3G (free) and I wouldn't trust my valuable data to it.
    For me, Paragon NTFS has been flawless and trouble free and I would highly recommend it to everyone. I know it's not free, but it's a pretty small price.

    The method where you modify fstab file doesn't seem to work anymore on Lion :(

    I just tried the Paragon NTFS trial version and it works fine in Lion, I was able to format to NTFS and then read and write from NTFS without a problem. Thanks.

    Here is the link if anyone wants to try it.

    Wonder why they won't mount then. I have Paragon installed too. I don't want to reformat these drives, obviously, since there is data on them.

    NTFS Lion

    To read/write NTFS on Lion I had to delete the folder 'ufsd.fs' from /system/Library/filesystem

    I installed a third party NTFS driver (Paragon 9.0.1 worked for me)

    Now my NTFS drive mounts and I can read/write.

    Hope that helps.

    I am quite interested in Paragon to be honest. Anyone have any idea if it is a native 64bit application/preference or 32bit? What about Tuxera? I thought Tuxera is native 64bit, isn't it?

    Thanks all.
