DBCC NEWALLOC
Checks the allocation of data and index pages for each table within the extent structures of the database.
Important DBCC NEWALLOC is identical to DBCC CHECKALLOC and is included in Microsoft® SQL Server™ 2000 for backward compatibility only. It is recommended that DBCC CHECKALLOC be used to check the allocation and use of all pages in the specified database. In a future version of Microsoft SQL Server, DBCC NEWALLOC may not be supported.
