27" i5 imac waking from sleep?

[SOLLERBOY]

Hi, I've noticed recently that when my imac is sleeping it's HDD spins up, crunches a bit like it does and then power down again. The screen and everything else is off, just the HDD comes on. Does anyone know what this could be? It's happened a couple of times in the last week. It's the Seagate drive BTW. Thanks.:)

Have you checked "Put HDs to sleep" from System Preferences -> Energy Saving?

Just checked, that box is ticked.

Try repairing permissions with Disk Utility then

Had a similar prob, I unchecked Wake for network access and it stays asleep.

Just done this, hopefully it will be ok. Thanks.
