hey guys! i have noticed some weird noises while moving my 12" IBook 1.2ghz. After listening closer i could identify the harddrive making that noise. it only makes the noise if i move the laptop. it doesn't make any sound at all when it's on a desk or something. everything is working fine and it has been doing that noise for about 2 months now. the SMART status is ok too. i backed up my data as i always do.. is that normal? should i have it checked out? it makes this noise like a bee, just like if something like the disk was scratching on the case while spinning. any suggestions?
