Panasonic UJDA750 (MT-A)

Hi everybody
As somthing of a computer novice i’m throwing myself at your mercy - I’m currently trying to install a Panasonic UJDA750 (MT-A) into my DELL Inspiron 2650 with little success.
The system will not recognise its presence at all - it doesn’t appear in either of device manager or BIOS, and yet the drive has power and will spin a disc.
I have been informed that some firmware may provide the solution to this problem… Possibly version 1.51 DL-Z?
Is this correct? or is there another solution?

If anyone could help me I’d be very grateful…
