I have just purchased a Sony DW D56A-11 Dual Layer DVD burner to upgrade my Sony Combi DVD/CD-RW in my Dell Latitude C840.
When I have the D56A-11 installed in the fixed bay of the Notebook it is not detected by the bios and the Notebook also fails to detect the Harddisk. I have tried flashing the bios of the Notebook to various versions and back to the latest version, I have changed the jumper settings on the HD to Cable select, Master & Salve but the same problem occurs.
Has anyone here got this drive installed in Dell Latitude C840 or older and does it work ok.
I’m begining to wonder if the unit is defective. I may have to try it in another machine to see if this is the case.
Any help appreciated
