Hmm... even though it's not a system drive for me, I do find it annoying that it takes a couple of seconds to respond when it's gone idle. I think I will disable the timer completely. Even if this means it will consume more power, how much more can that be anyway? It only consumes 6 watts when reading/writing and supposedly 3.7 Watts when idle. If this means the drive will consume 6 watts all the time (doubtful), I can live with that.

Thanks Mark!
