RAM, GPUs & fans are also nonzero power consumers, so any reduction in HD power consumption in typical desktops and laptops is minimal in the grand scheme. OTOH, loss of backward compatibility means accelerated additions to landfills of otherwise perfectly useful hardware. It should be fine to have an option for larger sector sizes, but it shouldn't mean extinction in the foreseeable future of a happily working standard for those who only want to replace a HD when the HD dies, and not commit whole systems to landfills for want of a generic component. Sounds to me like the HD manufacturers want to make 512 go the way of PATA, accelerating obsolescence to drive up profitability of the whole computer hardware industry. People shouldn't have to buy whole new systems for want of replacing a dead 20GiB 512 byte sector HD. -- "The wise are known for their understanding, and pleasant words are persuasive."
