Been running an 8Tb WD Purple for about a year with no issues. All of a sudden BI is saying I have "Drives Overallocated". Disk manager shows 7400Gb usable and healthy, and have had BI recording up to 7200GB (New) and 50GB(Alerts). The E: drive at the bottom of BI camera window showed -514.6GB so I changed my (New) folder to 6900GB and ran another DB repair it now shows E: -214.6Gb. Why all of a sudden is there not room on the drive and why would I need to lower the capacity another 200GB.
