NTFS drive does not mount under Lion.

exactly, just deleting /System/Library/filesystems/ufsd.fs solved the problem for me!!!!

Nick, can you tell me where is thie filesystem?

I can not find this file:-

NogaMacPro:filesystems nmondal$ pwd

/System/Library/filesystems

NogaMacPro:filesystems nmondal$ ls -al

Looks like there is no **ufsd.fs ** here on ntfs-3g. I think **ntfs-3g.fs** is there, but it is not mounting.😕

Removing the preference panes, I can have readonly access to my hard drive, but it can not have write access.

Any help would be appriciated. 🙂

The exact error that comes is this:-

NTFS-3G could not mount /dev/disk1s1

at /Volumes/Noga_Serials because the following problem occurred:

/Library/Filesystems/fusefs.fs/Support/fusefs.kext failed to load - (libkern/kext) link error; check the system/kernel logs for errors or try kextutil(8).

the MacFUSE file system is not available (71)

And that is because, there is no ***/Library/Filesystems/fusefs.fs/*** directory.

just give a look to the answer given by Nik pel end of page 1

The volume is getting loaded for read and write now,

however - there is an error coming from NTFS-3G:-

NTFS-3G could not mount /dev/disk1s1

at /Volumes/Noga_Serials because the following problem occurred:

Did not receive a signal within 15.000000 seconds. Exiting...

I am assuming that is an issue with NTFS-3G and Lion, perhaps ?

Hi,

I am having the same problem as everyone else with my external hard drive (which has my life on it). Everyone has been posting to delete /System/Library/filesystems/ufsd.fs however I have no idea how to do this. If anyone could help I would be extremely greatful.

Thanks

Ok, this is how I solved this problem. Following Nic Pel's method:

1. I uninstalled every NTFS driver that I had on my Mac.

2. I restarted.

3. I deleted the file on this route: /System/Library/filesystems/ufsd.fs

(I did a backup of the file, just in case)

4. I reinstalled a NTFS driver, (I used Paragon NTFS for Mac v.9.0)

5. Restart again.

6. You're done. You should be able to mount your external NTFS drive.

Good luck!

😀

Hi mandy2010,

here are the things you *should* follow step by step.

1. Assuming you have ntfs-3g installed, then,
2. Go to System Preferences
3. Find ntfs-3g and macfuse.
4. Uninstall them
5. Delete the prerences options of macfuse
6. Now reboot the system.
7. Install ntfs-3g from : http://www.tuxera.com/mac/tuxerantfs_2010.12-RC.dmg
8. Install http://www.tuxera.com/mac/macfuse-core-10.5-2.1.9.dmg [VERY IMP STEP]
9. Reboot the system.
10. Now insert your USB NTFS hard drive, and it should get mounted for read/write access.

Please note that it would give a nagging warning

NTFS-3G could not mount /dev/disk...

at /Volumes/.... because the following problem occurred:

Did not receive a signal within 15.000000 seconds. Exiting...

And it is fine, the read write is proper. Do not worry. Feel free to bug me, in case anything needed.

I can't find /System/Library/filesystems/ufsd.fs?

Thank you very much. It worked for me too.

I had the same problem with my three drives. I have a Free agent go flex drive, my book, and a seagate usb external drives. If you click here: http://blog.philippklaus.de/2011/04/fix-sshfs-with-macfuse-on-mac-os-x-10-6-7-sn ow-leopard/ you will find the MacFUSE program that you can download and install.

I installed the program, disconnecte my drives, reconnected them and they now work. You can also restart your computer and they all work. This is an easy fix.

Hi,

Thanks for your help. One more quick question: My Mac is now reading my external hardrive and I can save and edit my files. However, if I try to search for file it can not find anything. Is this because I have not purchased the full software (though when I was on leopard this was not a problem) or something with Lion?

Thanks in advance

Mandy

Nmodal ,

Thanks a ton for the help....

I faced the same issue. I uninstalled my MacFuse from my MBP and installed the one available from here:

It works like a charm for me.

Cheers!
