Ever heard a laptop scream to be turned off? Sound clip That noise came from 2 of a batch of 7 laptops. The noise comes from the HDD’s and the bearings in them. They had a good run.
This would be the reason why a PC would have loud fans: (taken at work) Windows 7 now comes with “diskless” option? The following is the options I have on my laptop when I click on “Safely Remove hardware and Eject Media”. The reason is because my laptops’ HDD is in a caddy usually reserved for a DVD (Lenovo T410s). I haven’t tried to eject the C Drive yet. It makes sense, although it’s stupid.
