[CentOS] Formatting hdb?

Dear friends:

Using Centos 5.

I have two physical drives. During install, I made sure to check hdb as well 
as hda. Both were listed as partitions (which is correct). But my fstab file 
does not show hdb. How do I make sure that hdb has been formatted and is part 
of my file system. If hdb is not formatted, how do I format it, please. Sorry 
for the question. I am a newbie.

d[sher at localhost ~]$ df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00

/dev/VolGroup00/LogVol01 swap                    swap    defaults        0 0

Thank you so much.
