    Hey All,

    Wanted to see if people had experienced sleeping problems when an external hdd is connected. I have tried several external storage devices, including OWC Ministack but it won't sleep and the external device will wake it up. I have tried to look at what is keeping it up through terminal but search has not turned up anything.

    I have two external drives always connected and my Mini has no problems at all with sleep.

    It actually sleeps when I don't want it to (due to Mountain Lion… DOH). Here's where terminal's command 'caffeinate' comes in handy.

    That's good to know if others are not having these issues as well. I wonder what externals you have as in what type of USB chipset is connected. Is this on a 2012 mini?

    As above, I also have the opposite problem. My narcoleptic mini wants to nod off during handbrake encodes, and even puts external HD's to sleep in the middle of file transfers. :rolleyes:

    Yes, 2012 Mini. A 1TB FW800 iomega drive and a 1TB USB2.0 Toshiba one.

    Option 1 is to disable sleep, which I don't like.
    Option 2 is to open terminal and type:

    $ caffeinate -t number

    Where number is a number of seconds. If you estimate the Handbrake is gonna take for lets say 7 hours. Just type:

    $ caffeinate -t 25200

    It'll stay away for 7 hours. Then will go to sleep as normal.

    Thanks. I actually downloaded the caffeine app after I discovered the problem. Hopefully it won't be an issue from here on.
