I've used this software with Snow Leopard and was very satisfied. It does its job perfectly. I've copied 140 GB of movies to a NTFS USB disc without any problems.

However it seems it doesn't work with Lion. Anyone has any idea?

Be careful, you can not eject the external drive, the NTFS partition. . . .
A kernel panic for the occasion!
Deeply discouraged. . .

OMG! This works...perfect! a big, big, THANKS.

Sits in the menu bar waiting for read-only NTFS volumes, and bang...all you have to do is select the volume form the list and its automatically unmount and remounted read/write. Seem pretty stable, efficient, handy, etc., and all the other positive buzzwords. This has earned a place in my crowded menu bar. All it needs is a better Finder icon as well as a better Menu bar icon ;-)

I hope to have some time to do some controlled performance testing to determine what the average I/O rates are as compared to HFS as well as the Paragon and the NTFS-3G. I encourage others to share their performance metrics.

Anyway, as with any 3rd party development (free or paid) use at your own risk. Your data is your data...you have to assume the responsibility for what you install and use on your computers over and above what Apple provides. If its a paid-for and a warranted product then sure, the vendor has a service level they should address if you encounter problems that their product caused (ie data loss). But a product that someone develops (and probably uses for themselves) and then shares with others is just plain kind and in the spirit of open development...blah...blah...blah. I provided criticism to this dev in my 1st post and it was constructive and I hope it helped the dev put out a better solution. I encourage others to provide constructive comments not trash talk ;-)

Well thanks again and BTW...I'm kicking my rating up a notch.

Cheers!

IIt works and it's free, can't ask for much more. Thanks!

First of all a bit of praise and a thankyou for this app and the effort. Things I like are:
- That it is a menu item that is out of the way, out of the dock, and easily accessible
- I really like the ability to access NTFS and read/write.
- The simple interface is welcome

What is troubling though is that it is awkward to use based on the following descriptiopn (I could just be doing it wrong but this is the problem):
- With NTFS Mounter running, the first time you mount an NTFS volume, the volume is read only but shows up in the NTFS Mounter list of available volumes...OK
- When the NTFS volume is selected, an NTFS Mounter Error instructs that you must eject/unmount/eject the volume...OK
- When the NTFS volume is unmount/ejected in the Finder as instructed above it is no longer available to NTFS Mounter...not good...The act of unmount/eject basically removes it from the bus that it was plugged into (USB/FireWire) and it can no longer be seen by NTFS Mounter
- Remedy: by this point the external NTFS drive is no longer visible on the desktop (unmounted) nor connected (ejected) on the bus. I unplugged and plugged it back in and it mounts as before in read only mode but instead of unmount/eject in the Finder I used Disk Utility to unmount (only...not eject) at this point it is visible to NTFS Mounter to mount it in the Finder as read/write.
- Cumbersome but it works

The next thoughts I had were around performance. I found that older NTFS drivers had poor read/write performance as compared to using HFS on the Mac or NTFS in Windows. I found that NTFS-3G performance was not as good. And I also tried the retail Paragon NTFS driver which was comparable to native speeds but of course it was a little bit more expensive than free :-) It would be interesting to see what other peoples experience performance wise is with this implementation.

Thanks for the tool.
