G5 iMac Superdrive problems

Ok, so my shop customised 17" G5 iMac arrived a couple of weeks or so ago. I tracked it all the way from China to the UK - amazingly it all worked when I took it out of the box... until I tried to burn a CD. The machine made the most awful humming/vibration that sounded like a cross between a washing machine and a hair dryer. It could be heard in a different room. I quickly realised this was not something Jonathon Ives would design into the iMac :O

The first disk burned but subsequent disks won't even burn, they just fall over after an interminable wait with some random error.

I am not massively happy, has anyone else had problems like this? I am going to phone Apple tomorrow. Will they send a replacement drive out or will they courier the whole thing into base (I ordered it through the Uk Apple Store)?

Lucklily I have my trusty old G4 Powerbook but still, the damn iMac wasn't cheap.

Yeah it does. I phoned them form work but needed to be at my iMac apparently for them to do some diagnostic stuff. I tried phoning after work but after been queued on hold for 25 minutes hung up. I will try them on Monday if I can get home before 6pm.

I did try the new Apple support chat client - where you get a chat window with an Apple support agent. That was going well until, while looking for the order date of my iMac in my in box, he terminated the chat because I had not responded (in 10 seconds or something stupid). So that's a good technological idea that needs some more work before prime time.

Hopefully they'll just send me out a new drive in the post - I can live without burning for a while.

Shame, otherwise I'm really pleased with the iMac.
