Microsoft usually recommends you to use a SAN (Storage Area Network) or locally attached hard drives to store your MS SQL Server database (MDF or Master Database File) because it optimizes the reliability and performance of Microsoft SQL Server. Use of the network database files (the files stored on NAS [Network Attached Storage] or networked server) isn't enabled for MS SQL Server. However, this configuration may damage your SQL Server database in some cases of system failure. In such situations, you must have an absolute backup of your significant database to extract inaccessible data from it. In the other case, you need to go for master database file recovery solutions to get your valuable data back.

Although, network file support is not enabled by default in Microsoft SQL Server, you can manually configure MS SQL Server to store all your database files on NAS storage server or networked server. The servers, which you employ for this configuration, must fulfill MS SQL Server requirements for write-through guarantees and data write ordering...

The DBCC CHECKDB command in SQL Server databases is used to check and repair any inconsistency in the databases. There are many extensions for this command that you can apply in various kinds of situations. However, at times when you this command finds any error on the system tables then it ends abruptly. Such cases can arise due to corruption in the database tables. In such situations, you should employ certain in-built workarounds to get the database repaired. If you are not able to recover the database using these methods, then you should use a third-party SQL database recovery software to recover SQL database.

Consider a scenario wherein you encounter the following error message while working on an SQL Server 2008 database:

"System table pre-checks: Object ID O_ID. Page P_ID has unexpected page type PAGETYPE. Check statement terminated because of an irreparable error."
