Hiya, and thanks to all for the replies. The instructions do indeed emphasise the need for 80 conductor cable for maximum DVD writing speed, though I couldn't see any reference to UDMA4 mode. The ribbon connector that I unplugged from the old drive fitted perfectly into the new. What is UDMA4 mode? Excuse my ignorance! Is it possible on my 4 year old Pentium VI Windows 2000 Professional machine with Gigabyte motherboard? I have indeed installed it as a MASTER drive.
Nero 5 appears to recognise it under Select Recorder, but that is as far as it gets.
The vendor will be despatching the missing OEM Nero Suite 3 "when his packing staff are in". The new drive came wrapped in a grotty polythene bag (not sealed) with the instruction sheet and absolutely nothing else, though in fairness to the vendor the transit packaging was bombproof.
I have since tried using Roxio CD Burning via Windows Media Player and succeeded in burning a disc that works perfectly.
I have to learn somewhere. This is the first time I've had the sides off the PC base unit - it looks an horrendous mess inside, and not at all encouraging for my second intended project of adding some USB2 ports!
