Energy Saver and External Drives
Simple question:
I use mostly laptops (PB and MBP), which are left on 24 hours a day (no sleep, screen dims/shuts off after 15 minutes, hard drives sleep after 10 mins). I've had no problems with any of this, but I have a question to which I can't seem to find the answer at the moment ->
What's a terminal command (or pretty app-wrapper for same), which will prevent the external hard drives from sleeping? I have a RAID, coupla FW800 disks, and assorted smaller disks attached to the laptops. Whenever I click on something, I'd prefer not to have to wait a few seconds for the external drives to spin up.
How do I leave all the energy saver prefs AS IS, and change only the sleep for EXTERNAL DISKS (not the internal one).
Thanks

I think (but am not sure) that the external drive sleep is controlled by the enclosure board. I suggest that you compose a shell script such as:
#!/bin/sh
ls /Volumes/external_drive1
ls /Volumes/external_drive2
and then automatically run it in whatever has replaced crond/crontab every ten minutes or so.
