Does the Sleep Option in Windows shut down menu spin down the hard drives?


I running windows7 home premium.  Does the sleep option in  windows shut down spin down the hard drives?

Does the option selections in the Power Management system affect the windows shut down sleep, hibernate system located in the windows icon at the bottom left of the desktop?

Sleep stops the hard drive. In a good machine, it parks the head. Close the lid, let it sleep and the hard drive is off, parked and safe. I carry my machine around in my briefcase that way.

As I understand your second question, no, sleep does not change the operation of the icons.

Thanks,  sorry,  I forgot to include my system info in my question.

I use a desktop computer designed for graphics and photo production with 3 removable computer cabinet drives and two computer cabinet internal stripped array drives.

So, I suspect that the hard drives may not turn off in using the start icon sleep option.   I seems that the system restores from sleep with a few seconds.  Would that be enough time for the drives to spin up and initialize?

In terms of "a few seconds" for the drives to spin up, I would say yes. My machines come back from sleep in a few seconds.

Are the drives going off? I would listen for them.

Now on the other hand, workstation drives are happy to run forever. There is probably no need to stop them.

I let my desktop computer run (2 drives but not in a RAID configuration) and let the monitor go black. It is fine like that and I think the drives are just as happy to be running. Good commercial drives are made for continuous running.

Workstation drives are different than laptop drives.

I just used the desktop Sleep option on my Windows 7 desktop and the drives stopped (I heard that and the drive light went out).  Normally the HD light flickers here and there but it is not flickering and there is no noise.
