I bought a new DVD writer and if I tilt it from horizontal I can hear something slide then clink. If I shake it abit it I can hear rattling. I was abit perturbed but installed it anyway and everything seems and sounds normal in the system. I did a Linux install with no issues.
I just wondered if it was normal or whether to expect this drive to fail in the near future.
I wouldn't worry about it, seems like all my newer drives make a lot of odd noises and rattles, now that they are a commodity they are not as solidly constructed. Just use it and if it fails, get a new one -- after all it isn't like a HDD that stores your data.
