Hi, guys.
Since I am a dummy, I thought many people like me could find this guide useful.
Here you are.

Open Terminal.

If you've already attempted to install the NTFS package:

Otherwise, download
MacFUSE DMG Installer
NTFS-3g DMG Installer

Install MacFUSE first and then NTFS-3g.

In the Terminal, type:


(you can copy and paste the code I have written here)

Press enter.

Now launch Disk Utility (Applications/Utilities/Disk Utility).

Select the NTFS partition you want to write on. Click on "Information" (the blue "i" on top of Disk Utility).
After the name and the type of the partition, there is a list of data. Read the first one, disk identification: in my case it is disk0s1

Note down the name (in my case it is WinXP Pro) and the disk identification (in my case "disk0s1")

Close the info window and click on the button close to the blue "i". This should let you unmount the ntfs partition you've selected.

Now in the Terminal, type:

Of course substitute "NTFS partition name" with YOUR ntfs partition name (in my case "WinXP Pro"), but keep the quotes before and after that!

Now type

A blank text file will open in the Terminal window. Here type



Here also, substitute "NTFS partition name" with YOUR ntfs partition name (in my case "WinXP Pro"), but in this case DO NOT use quotes.

Close (Command+x), save (type "y") and exit (push enter).

Type (always in your Terminal)

(you can copy and paste from here)

This will open another text file. Look for the line "/sbin/autodiskmount -va".
Go after that line with the arrows of your keyboard and type

(you can change Windows to whatever name, but write only one word, i.e. NO SPACE!!!)
(you have to change "disk identification" to your disk identification you've noted down before.)

Close (Command+x), save (type "y") and exit (push enter).

type "exit" in the Terminal and reboot your computer.

If you've done everything properly, you should see your NTFS partition on the desktop after booting and you'll be able to modify it as you want.

Enjoy.
