External HDDs sleeping even though I set them not to sleep

[patent10021]

After I updated to 10.8.3 my external HDDs sleep even though I've used the correct settings. A real pain since I have to wait for the disks to wake up whenever I access those HDDs

Any advice?

Thanks

There is a difference between display sleep and computer sleep. It sounds like your display and computer are both going to sleep at the same time.

If you have indeed set your computer to "never" sleep, then something else must be going on.
My first thought is to open the Console utility and see what messages are being written to the system log when the display goes to sleep.

Yes both at same time. Annoying. Before 10.8.3 both never would sleep. Will take a look at Console.

I had this issue. To solve it I adjusted the prefs locked them rebooted then reset the existing prefs and locked them.

Hope that makes sense

After I updated to ML my external disks sleep whenever my display sleeps. I et my display to sleep after 15 min and disks to never but they still sleep. A real pain since I have to wait for the disks to wake up whenever I play media from those disks.

Any advice?

Thanks

Two possible issues.

First is did you check your computer sleep time? The drives will spin down when the computer goes to sleep.

The second is some drives have their own spin down timer. Although I think the default on Seagate is to let the computer control the spindown of the the drive, so I'm betting the issue is the computer going to sleep.

There is a separate toggle to allow hard drives to spin down. So regardless whether you have the computer set to never sleep, you still have to uncheck the box that says spin down hard drives when possible.

yeah all those are already set to prevent sleep. Was working in 10.7x but not in 10.8.3. HDD sleeps when I don't use it for a short while. Can't say exactly when but it's after only a very short time.

 

[patent10021]

Darn, trashed the PwerManagement prefs but my external Seagate and WD HDDs are still sleeping if I don't access them after only 10 minutes or so. Sooo annoying. They weren't doing this in 10.7x.
