I just got my first mac! (300mhz tangerine clamshell iBook w/ 288mb ram, 80gb external HDD, and printer. all for $150!) Anyway, I allways take my laptop to school. Latley I have been putting it in sleep, so I can open it up quickly to take notes. However, I am worried that the jostling that occors while going from class to class coud damage the HDD. Am i over protective? Or is this a possibility?
