If you look in System Preferences you should find an icon for MacFuse. If you go into that there should be an option to disable or even uninstall it there. If you select the uninstall option it bizarrely still leaves the icon in System Preferences - you can hide it tho', as you can anything else in System Preferences.
NTFS-3G is third party software that allows your Mac to read/write to Windows NTFS formatted drives.
Upon booting the computer a kext file (kernel extension) loads into OS X to allow this, it's using Fuse.
Fuse.kext is not loading, thus when you connect your NTFS formatted Windows drive, it's not working.
Like Linc Davis says, go to the NTFS-3G website and update the software.
Or if that doesn't work then use this
Once you've got your data off the drive (if there is any), consider this:
If you are using the drive for Mac use only, then format GUID OS X Extended (J) in Apple's Disk Utility.
If your using the drive between Windows and Mac's, then format it exFAT (for 4GB+ sized files, less compatibility) or FAT32 (best compatibility) between the two types of operating systems, and format it on the Windows machine, not on the Mac.
The reason for this is Mac's can't natively write to NTFS drives, only read, so instead of having to pay and/or upgrade third party software, you can just use a native format both computers can read easily. Less hassles.
Also when you change a format of the drive, all the data will be destroyed. So it must be removed first.
Since you mentioned it's a new drive, it might be blank and formatted NTFS, so all you have to do is change the format.
This solution helped me without problem, since I couldn't finish last step, immediately after that could not mount stopped. I have Lion 10.7.5 Macbook Pro 2011 and have NTFS Mac-fuse solution installed from early beginning. Don't stop be interested in know, there are solutions for Paragon and some other to. This looks quite dificult for me at first look but now I finally tried it and it takes about 10 minutes. Just don't be scare if you don't know terminal yet, then you'll be prompted to type password it looks like you can't type but you can. Just type and press enter.
Here's the link http://fernandoff.posterous.com/ntfs-write-support-on-osx-lion-with-ntfs-3g-f (sometimes it takes little bit longer to load)
Hope it helps
PS: Sorry, I don't have time to read everything, just found working solution so I decided to post it everywhere
