Booted up a minute ago and got this horrible vibration/rattling sound coming from my case. I couldn't locate the sound before it stopped, but having heard the stories I'm worried it's my 1Tb sammy F1 on its way out. It's only a few months old and used as a storage drive so I'm hoping that's not the case (HD tune shows everything as fine). Can anyone else let me know what signs I should be looking out for if it is?
