Identifying partitions

I have very recently installed Ubuntu 9.0 and now I have multi boot system
My PC is fitted with two hard disks.While I Am on Ubuntu Eventhough I could access all the partitions I am not able to identify quickly the partitions because
the information displayed as new volume,new volume .etc.request guidance to access the partitions in a manner so that identification is easy.Hope I have explained my difficulty properly.thanks

 

How are volumes displayed on your system? What's the output of

Code:

fdisk -l

?

 

as it's ubuntu it needs to be:

Code:

sudo fdisk -l
