Any way to stop external HDs sleeping without a special app?

    Is it correct that the "Prevent HDs sleeping" parameter in Energy Saver only applies to the internal drives, not any externals?

    That being the case, is there really no permanent way to prevent external drives sleeping other than to install a dedicated app to keep them awake?

    Just curious, but why don't you want the drives to sleep?

    The enforced pause while you wait for a drive to spin back up again breaks your flow and can be maddening.

    I have my drives set to sleep after 2 minutes of inactivity. I'd prefer not to hear them spinning.

    Some makes of external drives will go to sleep on their own and I think only way around is have a program access the drive on a regular basis.

    I don't think so.

    No, it applies to external drives as well. At least, the ones that respect the setting—which not all external drives do.

    Also make sure your drive-specific software has its setting to sleep when not in use turned off.
