random thought, but i've read about the 5400/7200rpm hard drives having safety locks that will snap into place to prevent the hard drive from damaging itself or something like that? well just moments ago i lifted my mbp while it was running off my lap and placed it onto the table in front of me. and within that quick motion of lifting and placing (i placed it softly) but while it was in the air, i heard a quick screech. just thought of that was the 7200rpm scratching against the inner wall or w/e. but common now, laptops are meant to be portable right? how easy would it be to cause any damage to your hardware while moving it around? or is the only way to cause real damage to your hdd or any other hardware is by droppin it or hitting it? thanks for reading!
