New hard drive setup for Linux redhat

Hi guys,

My /home dir is getting bigger, I just added a new hard drive to my linux machine. After used "fdisk" to partition and format the drive with "mkfs.ext3 /dev/hdc1" . The new drive is called "/dev/sdb1"

I'd like to move /home dir to new hard drive, currently the /home dir has few users accounts . How do i move that /home dir to new hard drive and keeping all the user accounts ? That means the new hard drive will be the /home dir.

Here is the 'df -l" after partition and formated:
==================================
[root@redhat ~]# fdisk -l

Disk /dev/sda: 146.8 GB, 146810536448 bytes
255 heads, 63 sectors/track, 17848 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux
/dev/sda2              14       17848   143259637+  8e  Linux LVM

Disk /dev/sdb: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       60801   488384001   83  Linux
[root@redhat ~]#
================================

Any idea ? Thanks.
