OS X Yosemite always mounts usb-hdd to the new folder
Firstly you should not need any extras to mount NTFS drives.

You do not make it clear what you want to achieve.

I have an old FreeAgent I used for Windows backup. I DON'T want it to automount, so I have the following in etc/fstab see edit detail below

#
# Warning - this file should only be modified with vifs(8)
#
# Failure to do so is unsupported and may be destructive.
#
UUID=E00F307A-9295-482E-8A79-2FA2C922F3CD none ntfs rw,noauto
⋯
LABEL=Tempy none ntfs rw,noauto


I can use DiskUtility to mount if I want to access these.

If you want to auto mount in a specific directory you can create an entry to do this. If you do create a directory and edit fstab.

NOTE you should use vifs, which requires a knowledge of vi commands, so you should look at man vi to discover the basic commands.

 :q! quits
 :wq saves
