That perhaps was true for some older drives, that spin down after a few
seconds, but it anyway required something to wake up the drives again.
Howvere, it's untrue for those drives that are just a few years old. My
spins down after 30 minutes, and stays a sleep , if no evil software
touches it. I never had to use a tool, which anyway wouldn't have
worked, because it's an USB device.

By an EU Regulation all external drives must go to sleep after a while.

I already explained why this happened. The spins for your drive might
not have happened within seconds after using this utility, but as for my
drive, when using bad software, what I usually don't do, every 30
minutes or something around this. I bought my WD green drive 2013-02-27
and never had an issue, IOW it's nearly 4 years old. As already pointed
out, I don't use gvfs, smartd and similar software that touches the
drives and enforce a spin up, directly after the drives goes asleep.

You spread FUD about WD drives.

Ralf
