Re the CDL, here's some stuff from Dweb that will show some pics and give context. Worth noting that as rough and tumble as Discoweb can be for the uninitiated, every question for an NAS D1 and Dii has been asked and answered there multiple times over (in fact the biggest problem with searching now is you'll find threads that point you further back in time).
