What are the "IO operation at logical block address" errors I'm seeing in the event log?

These errors are caused by a third-party DLL library Drive Bender uses with its S.M.A.R.T. service, Hard Disk Sentinal (our feature to monitor the S.M.A.R.T. status of drives). The specific library, enumerates all drives, including any Drive Bender mount point(s). Because a Drive Bender mount point is, in fact, a virtual drive, this library is not handling the volume correctly, and then is reporting an error to the Windows Event log.

Other than the event log entries, this has no other system impact, and in no way affects the underlying drives in the pool.

Update - The libraries used were updated before the release of v3, however, we still get the odd user report the notification.
