Other projects • Re: GPIO wake up

I have tried to have the hard drive sleep, but it seems impossible with

Code:

hdparm

. It shouts at me like I gave illegal commands.

That's not very helpful. If you really are getting a "command not found" error try:There are plenty of low cost I2C RTC modules available most of those should be able to trigger a Pi boot as long as mains power is present to the Pi.

Have you considered doing power control away from the Pi? A Mains time switch to turn on the Pi, then have the Pi do the backup then shut down, then have teh mains timer cut power?
