Drop test
My WD portable (can't remember the model but it's less than a year old) had absolutely no problem when I forgot it was in my jacket pocket and said jacket suffered a sizeable flying impact into a brick wall
The case broke (the outer edging came away and I can't get it back in place) but none of the data was missing/corrupt and the unit has been working as new with no issues
It's also suffered a few nights out with me where my attraction to the floor has overwhelmed me
Am I just lucky or are HDs just not as impact-sensitive as they used to be? Incidentally I've dropped my Vaio so many times the chassis has actually bent, but still no HD damage
Maybe I should just stop dropping things :-|
