I have made a couple of assumptions here. I am assuming that the NTFS partition is a Windows partition that has data in it that you need to access from time to time. In that case I would mount it in your home in a folder called Windows. If you want it mounted somewhere else and/or under a different name let me know and we can change it.
Also one thing that is confusing sometimes with NTFS partitions is the way Windows handles the locking. If you don't shut down Windows properly, ie. hit the reset button or force a power down, sometimes NTFS partitions won't mount correctly in Linux. The solution is to restart Windows and shut it down properly. Then restart Linux.
Open a terminal and type: (put your username in place of mine in all cases.)
gksu gedit /etc/fstab
A window will open displaying the fstab file for editing. Put the following line at the end of the file, save and close. ( I am assuming your Windows install is located on sdc1)
/dev/sdc1 /home/fred/Windows ntfs defaults,umask=007,gid=46 0 0
That is it. Reboot and you should have a folder in your /home named Windows. Clicking on it will open your Windows partition.
Bye-the-way, what happened to sdb? It is a bit unusual for a drive designator to be skipped. Just curious.
