This error message is from Idera's SQL Diagnostic monitor.
I am getting this critical warning on a newly built SQL Server 2008 R2 build. It is reporting this error for all the drives on the disk even the ones with no data on them.
I monitor 4 other instances and don't see this. Everything appears OK on the actual server when monitoring locally.
I think the tool is reporting this incorrectly. Any ideas or experience would be helpful.
