[CentOS] Changing the file type

I have a USB external drive that has not been used with my Linux 
system.  The HD is from a Windows system, so it has a NTFS file system.  
My manuals speak of the fdisk -t command to change the file type, 
however that does not appear to be available with Centos.  Could someone 
refer me to the steps I should use to change the file type, change to 
partition if necessary, create a Linux file system and then set it up so 
that when I plug in the USB drive it will automatically mount (if possible).
