Mount a ntfs external hard disk to Centos i386

I've Centos installed on a 32 bit system

Now I want to mount a external HDD of NTFS file system. I've read the article here and have installed fuse & ntfs-3g with the instructions here. I've installed the following libraries:

• fuse-2.7.4-8_12.el5.i386.rpm
  
• fuse-ntfs-3g-2009.11.14-1.el5.rf.i386.rpm
• fuse-libs-2.7.4-8_12.el5.i386.rpm
• fuse-kmdl-2.6.18-238.el5xen-2.7.4-8_12.el5.x86_64.rpm

Now I want to continue to mount using this command

mount -t ntfs-3g /dev/device /mnt/mountpoint

but I don't know the device name or watsoeva. the example given on the terminal is:

ntfs-3g /dev/sda1 /mnt/windows

But I don't quite get it. How can I find out my device name?

Update

I actually got this back from the result:

So how should I modify my mount -t ntfs-3g /dev/device /mnt/mountpoint

What is /mnt/mountpoint? Do I define that?

If you know the size of your disk, you can run 'dmesg | grep sd', and look for the disk in the output that matches the size of the disk you are useing (the ntfs disk). From there the sdX1, sdX2, sdX3 would be the partitions to be mounted in /dev, where X is the disk label
