I would probably go so far as to say that letting a drive sleep while not in use for extended periods of time (hours maybe, days definitely) probably might even help extend a drive's useful life in normal (well what the average HTPC/home user considers normal at least) usage, but really in something like 99.99999% of all cases, the drive will get replaced due to size or speed upgrades long before it fails regardless of sleepiness... (again in an average HTPC/home user environment... a datacenter could be a completely different scenario)
so just for clarity, what is assassin's official position?
A) HDD's are magical beasties that don't wear do to power/wake up?
B) HDD's are just like any other electromechanical device, and they do wear due to power/wake up, but that the wear from power/wake up is <= to the benefit of not wearing while sleeping (and the power savings are a huge bonus too)?
