I ran the DBCC UPDATEUSAGE command on our Dev box to see if it fixes the 'disk usage report'. It ran quickly ( 10 seconds) and ran successfully but did not fix the report. Any ideas about what the issue could be? Thanks!
These numbers on the disk usage report look correct. It's important to note that the Total Space Reserved is displayed in GB, using the conversion
1024 MB = 1 GB
The formula used by the above report is straightforward:
Data File Space Reserved + Transaction Log Space Reserved = Total Disk Space Reserved
279,860.56 MB + 90.63 MB = 279,951.19 MB 279,951.19 MB / 1024 = 273.39 GB
