NZBDrone keeps asking for disk size, causing disks to spin up

So NZBDrone keeps requesting the size for one of my external drives, which is encrypted using Truecrypt so it’s unable to retrieve any information about it. It doesn’t really bother me, but repeated requests cause the disk to spin up needlessly. Is there any way I can tell NZBD to ignore a certain drive?

Here’s the error from the log:

Message:
Unable to get free space for: I:\: I:\

Exception:
System.IO.DirectoryNotFoundException: I:\
  at NzbDrone.Windows.DiskProvider.GetAvailableSpace(String path) in m:\BuildAgent2\work\328d72309b633a8\src\NzbDrone.Windows\DiskProvider.cs:line 29

It will attempt to load the disk space whenever you navigate to the System - Info page. It does this for all attached drives whenever that page is hit, there is not way to exclude drives at this time (nor is it in our backlog to do so).
