I have a MacBook Pro and periodically I hear a hissing/static sound coming from the speakers. My research to date indicated it could be a hard drive failure. I took my laptop to an Apple service center and paid for a diagnostic test. after 1 week they returned the laptop and stated they could not find any issues. Should I be concerned that they missed something and i will be experiencing a HD failure? Any thoughts would be appreciated. I utilize time machine the back up my files. Is this enough to insure I will not suffer a total loss?
