Hi , I have a DB which is reporting the following. EXEC sp_spaceused @updateusage = N'TRUE'; database_name database_size unallocated space GL***_*** 171804.38 MB 30246.53 MB reserved data index_size unused 140346208 KB 114488712 KB 25590816 KB 266680 KB The Primary File where I have the Tables is 143670656 KB. The Indexes are in their own FG's.. What I can't understand is when I run sp_spaceused on all tables it adds up to about 80gb. taking the unused space into AC I'm still 'missing' 31 gb . If rebuilt all the Indexes. I've ran dbcc updateusage Is there anything I'm missing. It's driving me nuts !!!
