Optical drive recognition problem ? (Panasonic UJ-210)

[qanda]This thread is about the Panasonic UJ-210. Click here to see full specs[/qanda]Hi there I have recent bought a Vaio VGN-FW11E and also bought a Panasonic UJ-210 BD drive. The BD drive does not come with this this laptop as standard but the VGN-fW11S (next model up) does with the model UJ-220 BD drive. Thinking it would be straight swap guess what fat chance.
When I changed the driver hardware did not show up in device manger. Even though VGN-FW11s has the same processor,graphics chip the only difference 50 GB of hard drive & 1GB of ram.
The thing is when I swapped the drives in my older Viao VGN- FS315S no problems apart from the graphics chip not rendering but recognises the hardware though. So what next is a hardware problem or a driver bios problem because the drive does not even boot up os software on start up.
I would be very grateful if someone give me some guidedence.
