Hard drives keep going to sleep

[openskies2009]

Im on a IMAC with the following external hard drives attached to my USBC ports.
G-DRIVE.
My Book.
G-Grive with Thunderbolt.
I have unchecked "Put hard drives to sleep when possible", but they keep going off every fifteen minutes or so. Makes my computer lag for about five seconds whenever I try to access them after this point which I'm an editor so this is not acceptable.

What can I try?

I've run into this before and usually it requires a firmware update to the drive itself before you can disable the built in sleep function. There are apps you can try but I honestly don't know how effective they are at keeping the drives awake: Caffein, and Amphetamine. You can also check with the drive manufacturer to see if they have a software solution.

How are the rest your sleep setting set? If the system sleeps, it may trigger the external drives to sleep too.

Everything is working but the drives

Options I'd try:

1. One of the "keep alive" apps mentioned above.
if that doesn't work...
2. Go to the energy saver pref pane, and set "computer sleep" to NEVER. See if that helps. No, the Mac won't sleep, but it -might- keep the drives spinning.

I have set everything to on, even this setting. I've tried to update the firmware but support is saying these drives dont need any firmware updates.

Then try using one of the apps I suggested above.
