lol im asking this because yesterday my oldie wd5000aaks when it was on suffered a small drop from 1 cm ( 0.39 inches) (from google conversion lol) and i see the drive powering down for at least 2 seconds and after that powering on again like nothing happened ( made the internal smart test check)
i feel that the drive spin down more quicly than normaly does when i shut it down
just for curiosity
