It's a thing like ESD: if you want to risk it. Not entirely true. ESD does permanent damage to the device even if it doesn't die. ALL (that I know of) drives have an internal air filter to pick up any dust that may appear so if the media is not damaged the air will be cleaned and reliability should be nominal (excludes the reason for first opening it). I have several drives I've had to open all running and all apparently living longer than average! Allison
