Clear server alert

Question

What is the appropriate way to clear a health alert on an SBS 2011 (Standard) server for the silly Event 2138 from Microsoft-SharePoint Products-SharePoint Foundation for a drive (including a drive that SharePoint does not even use) having less than five
times the size of RAM as free space?  This alert puts the server in Critical status.
Susan Bradley discusses how to disable getting this silly alert in her blog post at
http://msmvps.com/blogs/bradley/archive/2012/01/25/event-2138-drives-are-at-risk-of-running-out-of-free-space.aspx.  I have implemented this fix so that no more of these events will be logged.
However, once an event has been logged the server is placed in critical alert status (the Windows SBS Console, Network tab, Computers subtab shows the server is critical status).  I can clear the alert by disabling including "Immediate action may be
required due to a SharePoint error" event log error in the view notification settings.  However, if I re-enable alerting on that event log error, the server goes back into critical alert status.  I slightly suspect that the only way to permanently
clear this alert is for a SharePoint health check to see the drive with enough free space (which is never going to happen).  I don't know if that specific event log error alert setting is only the silly drive space health check or if other SharePoint
health checks use the same event log error.  (I suspect the latter.)  I would prefer not to disable other (legitimate) SharePoint health checks from notifications.

Hi Darryl:
If you are still watching this, can you advise if the condition has cleared?  There are several conditions that once they make it into the error/event system they take a number of cycles to clear.
It might/will be helpful to others to see if there is any finality to this issue.
Thanks for your attention.
