NTFS drive does not mount under Lion.

USB thumb drives use a different file system then NTFS, they are supported.

I think I have found another solution:

Just use the 'Safely remove hardware and eject' option on the Windows system first - it works EVERY time!

I have been having all the issues referred too in this post, and removed files, re-installed drivers (Paragon v9.5) etc, with no permanent solution.

But if you do a safe eject in Windows before using the drive on your Mac, it works.

The old NTFS-3G driver used to complain about disks not being ejected correctly, and give you an option to continue, but Paragon just ignores it and refuses to mount the drive.

This is clearly a bug in Paragon.

Thanks for the answers. I found the solution with the recent 2011.4.2 version from Tuxera NFTS. I guess Lion has been launched with many incompatibilities and third party programs are catching up later. Whatever it is, now I finally can connect my multimedia external NFTS drives ok.

This worked for me, thanks for the step-by-step instructions!

This worked for me for about 30 minutes and I was able to write data to the external drive but then it was suddenly ejected and now it won't mount.

I did all of that and I was able to write to my drive for about 30 minutes when it suddenly ejected and now I get this error:

Parter, I have the same problem. Been doing this for hours by following the steps discussed with no success. After unistalling the paragon, my 2TB WD HD was able to mount. However, wasnt able to locate ufsd.fs. Still could not on the the drive. Please help.

Hi everyone,

I am running Lion on a pretty new macbook with Win 7 on an ntfs bootcamp partition. I tried using Paragon NTFS to allow me to write to the drive but the drive vanished, and Disk Utility would no longer mount it. Turning the driver off allowed Disk Utility to mount the drive again, alas read-only. Several uninstall/re-installs later, I found this thread.

It seems like there are 2 problems, one is a general mounting problem that is fixed by deleting the ufsd.fs file.

The other is that paragon is very picky. I fired up win7 through parallels and shut down the machine properly. A re-install and a restart later and everything is working fine.

Thanks everyone for the posts, quite happy with the setup now 🙂

I'd like to report mixed success on getting my NTFS drives to mount.

Short Version: After following the directions Paragon NTFS still did not work but Tuxera NTFS did.

Long Version:

I have a Macbook Pro (Early 2011) running Lion 10.7.3 and with a Bootcamp NTFS partition on my system.

Before upgrading to Lion I had installed the Seagate software package which included a restricted version of the Paragon NTFS driver that only worked on the Seagate FreeAgent external usb drive.

Before installing Lion & after installing Lion read & write access to my external Seagate FreeAgent drive worked OK and I could read from my Bootcamp partition.

I recently upgraded my flash drive to NTFS so I needed a new NTFS driver. I installed the trial version of Paragon NTFS 9.5 and things worked OK for maybe a day.

About a day later my external Seagate drive failed to mounted when inserted. Using Disk Utility I checked, the NTFS disk state was dirty because it had not been cleanly ejected so I used Disk Utility to repair the NTFS partition.

This was the start of 8 hours of frustration. The disk utility hung the system during the last stage of the the NTFS disk repair and I was forced to do a hard reset. After this every time I rebooted my finder seemed to be hung? - got a spinning beachball, my desktop items didn't display (but could see them in terminal) and although some applications would launch, the system was unusable.

I had to boot to safe mode (and why doesn't anybody ever mention that having a firmware password quietly disables safe mode with no message or warning?) and uninstalled the Paragon NTFS. Rebooted. Cleaned the /System/Library/filesystems directory. Rebooted. tried to install Paragon NTFS again. Got spinning beachball hang again. So safe boot, uninstall, reboot, clean dir, reboot.

I installed the Tuxera NTFS and it's working OK.

So - I seem to have success.

Technical thoughts:

I don't have any proof, but my technical suspicion is that the Seagate limited Paragon NTFS left something in the system, maybe some kind of kernel extension, that interfered with the real Paragon driver. Or maybe the state of my Bootcamp NTFS drive is dirty and the Paragon driver was hanging up Finder on boot.

So - kind of makes sense that the Tuxera NTFS driver worked OK.

I'd love to hear if anybody else had the problem upgrading from a Seagate Paragon NTFS driver install.

A friend helped me out with this in the end.

tuxerantfs_2011.4.2.dmg works fine in Lion. Haven't had any problems since I installed it.

Hope that helps others out!

(Paragon NTFS 7.0.3 in Leopard)

If you are trying to remove 100% of Paragon NTFS and your comfortable working in the terminal deleting files you might want to checkout this link from the Paragon support board that contains a script listing all the spots bits of Paragon might be left on the system.

Hi,

Just plugged my 64Gb Kingston NTFS USB key on a windows 7 laptop...run the CHKDSK tips and ejected it safely from the "MyComputer" device list and right-click on it and EJECT....and back to my Mac IT WORKS !!!

USB key now available on my MacBook Air via Paragon NTFS and able to READ/WRITE !

Thanks for your tips !

Hi, just make

sudo fsck_ufsd_NTFS -y /dev/disk1s1

You need to change the permission on your external hard drive this is done easily on your PC prior to connecting it to your mbp

1 - go to start

2 - computer

3 - right click on your external hd

4 - properties

5 - select tools tab

6 - select check now

7 - select sharing tab

8 - select advanced sharing

9 - tick the share this folder

10 - select permissions

11 - tick allow full control

12 - select ok

13 - close

14 - select security tab

15 - select edit

16 - tick allow full control

17 - select apply (this is important)

18 - all your files will now be running through to allow read/write

19 - close

20 - ensure you eject safely otherwise the mac won't read it

That's it your done, now connect to your mac with the paragon NTFS software installed and it will have the read/write access available.

You only need to do this once on all your external drives no data is lost everything works perfectly on both PC and MBP just ensure you eject safely every time from both machines.

It works perfectly ! So simple ! So easy ! Thx Dvglazunov !

Write "utildisk list" in terminal to locate the ntfs volume before using the fsck_ufsd_NTFS command (for example for me it was "disk8s1")... and it works ! 🙂
