Secondary Hardrive not show up in Fedora

[psutinrerk]

Hello,

I tried to add secondary hard drive to my Fedora (guest) Window 7(host)

In the storage detail I have the following

IDE Controller
IDE Primary Master: Fedora.vdi (Normal 8.00GB)
IDE Primary Slave: Fedora2.vdi(Normal, 1.00GB)

but when I start the Fedora I can't find the Slave is there any reason why? do I need to mount the Slave?
I'm using Virtualbox 3.2.8

Thank you

Please show the output of "fdisk -l" from the fedora guest.

The disk is there, you just have to create a partition and a filesystem on it.
