Windows 7: Hard drive goes to sleep, and wakes up again!

Hard drive goes to sleep, and wakes up again!

Hi. I have Windows 7 installed on my MSI Wind U100 and I'm very pleased with it. I flashed the firmware of the little laptop and installed all the drives. Everything works great.

When the hard drive goes to sleep, it always wakes up again after 10-20 seconds or so. The only thing I have running in the background is Microsoft security essentials. This happens when I do absolutely nothing. Sometimes I leave a webpage open, or a Word doc to read it. It just fires up again randomly. I remember that I had set the same setting when XP was still on it, and I could even scroll through pages for a while without the hard drive starting again.

What could this be? And it can't have to do with superfetch or indexing, because this also happens when the laptop has been on for an hour.

It could be any number of background services waking the drive.

As a test, open Resource Monitor and pay attention to the "Disk" section. You'd be surprised how active it can be. (Start>type : Resource)

I see, but that basically means that there is no point in setting a sleep time for the HD, because it wakes up after a few secs anyway.

If it'd actually work how I want it to, I'd set it to a sleep time of one minute. This leads me to the next question. Is it bad for a hard drive to get shut down/restarted a lot?
