I use dual-boot between Linux 11.10 and Windows 7 on my laptop. There are Windows partitions:
C Drive - 360 GB
D Drive - 200 GB
E Drive - 80 GB
I installed Ubuntu in on drive F
which is 30 GB.
The drive E
is totally empty and I want to map this drive to Ubuntu.
Is it possible? If yes then how can I do it?
What you call "mapping" is called "mounting" in Linux-speak, and the file system used by Windows is called NTFS. There is a guide in the Ubuntu Community Wiki that helps you with every step along the way to getting your NTFS partitions mounted and ready to use:

As per comment from @Alexandre, here is a less comprehensive but more newbie-oriented guide that even uses a GUI tool to take care of the nitty-gritty details:
