Is there any way to see if a drive is currently asleep and powered down or active and powered up?

Is there a way to have the Disk_Log show when the drives sleep and wake up?

You can use the following command to check if the current hard disk is spinning:

smartctl -i -n standby /dev/sdX

If the hard disk is in sleep mode (not spinning), smartctl will return immediately without waking up the hard disk. If it is in an active state, smartctl will output information normally.
