Q: What does "Recovery HD mounted or unmounted" mean on a MacBook?

Growl Support

I, too, am wondering what it means that hourly I see Growl/HardwareGrowler "report" that the Recovery HD Mounts and Dismounts.

Was the "response" by CT intended to imply that their is a bug in Growler? While this could be, It isn't clear to me if this is a just Growler "reporting" or it perhaps that Growler is causing the Mount/Dismount behavior, as CT implies with the link to Growler tech support. I have seen this behavior for months, likely for more than a year, perhaps since the first time I installed Growl and HardwareGrowler a few years ago. I have wondered about it, but don't know that it is an actual problem.

In my case, I see this behavior on a 2008 MacPro running Yosemite.
