Have servers with up to 2 terabyte partitions and running disk reports throws an overflow error on partitions that large.
In the monitor test tab, Polymon shows the counter counter is E:.FreeSpace and value is 55602642944
When I attempt to run a report at the dashboard, polymon throws the error:
Error running report: System.OverflowException: Conversion Overflows.
Much SQL follows that I can't copy, but could re-type or attach in an email.
