Adding a secondary HD in CD device

Hello,

Since the CD unit stopped working I'm trying to use the space to put a secondary HD drive.

I bought a SSD where I installed Mavericks to use it as a primary HD and place the old one (Hitachi) in the CD drive.

(I'm using an adapter for hard drives where I'm trying to place the Hitachi HD)

I have a MacBookPro3,1 Intel Core 2 Duo. And these hard drives:

1) Hitachi 160GB 2,5 inch 5400 rpm SATA (old one)

2) OCZ-VERTEX450 SSD 128 GB. (new)

Hitachi HD won't show up if I connect it internally. I've tried to format it (using an external connection) with Disk-utility but no luck. It doesn't show up. I've tried all format possibilities without success.

If I check in "System Information" > "Hardware"> ATA> it's listed there.

Any idea how to fix this ?

Thank you !
