[CentOS] mounting & partitioning Seagate FreeAgent external HD

Hi all,

As a disclaimer, I'm new to this list and very green administering 
CentOS.  I run it on my test servers and do very basic networking and 
server administration (most users, permissions, and web app stuff).

I have a backup server that I am using rsync to collect important 
in-process file for our digital library from both Windows and Linux 
servers, as well as a specific applications which are updated on a 
separate test server.

This backup server ran out of space and I have no more internal slots 
available to add another disk, so I bought a 750 GB Seagate FreeAgent 
external USB hard drive.  I've seen some various issues out there about 
how Seagate FA HDs go into sleep mode when used in the manner I want to, 
but all of the people posting about that seemed to be able to mount 
theirs with no problem.

I can see the device in my /proc/bus/usb/devices file, but fdisk -l 
doesn't show it at all.  I was trying to mount and partition it using 
Webmin, but I can't figure out the device name I need to give it to 
mount and partition it.  How is the best way to figure that out?  This 
particular server is running CentOS 4.

Thanks,
Tim
