Is It OK to Turn on and Off a Few Times a Day?

It's my understanding though that if you shut it down in the middle of a scrub, when you boot it back up again, it'll start again. It might lose like an hour of progress because it only writes stuff down every couple of hours. But yeah, it won't hurt anything. If you're trying to limp along a drive to be like the oldest antique possible and still functioning, I would definitely say, yeah, don't ever turn that thing off.
