Database in SQL Server?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>MS SQL Server is a relational database management system (RDBMS) that supports various transaction processing and business intelligence and is offered &amp; managed by Microsoft. It is one of the most popular and advanced database management systems to store important data and information. It uses an MDF file to store an SQL server&#8217;s important files, also known as the primary database file of the database.<\/p>\n<p>And additionally, if we talk about the Master Database, it all means that the path or file where all the primary configuration details of the SQL server are stored. All the important information of the master database is stored in a physical file called an MDF file which contains the schema and the data, and the LDF file, which contains transaction logs. It all means that users&#8217; crucial login details are stored in the master database, which is MDF. But these days, users reported that their SQL Server Master Database gets corrupted or damaged. Well, there are several reasons behind these issues, which we will discuss in the upcoming section.<\/p>\n<h3 class=\"main_heading\"><span class=\"ez-toc-section\" id=\"Reasons_Behind_the_SQL_Server_Master_Database_Corruption\"><\/span>Reasons Behind the SQL Server Master Database Corruption<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Well, there are different reasons which are responsible for your Master Database(.mdf) corruption in SQL Server. Let&#8217;s know them all to avoid this issue in the future.<\/p>\n<ul>\n<li>Your Hardware failure is one of the main reasons behind the corruption in the SQL Server.<\/li>\n<li>Suddenly the shutdown of your local machine leads to corruption issues.<\/li>\n<li>Sometimes, attacks by viruses or malware on your SQL Server will damage your master database file.<\/li>\n<li>&nbsp;It also may be possible that users enter some wrong queries, and as a result, it corrupts your MDF files.<\/li>\n<li>Bugs in the SQL server are also a reason for the master database corruption issue.<\/li>\n<li>One will upgrade the versions of the SQL Server.<\/li>\n<\/ul>\n<p>No matter which reasons are responsible for your SQL Server Master Database corruption or damage. Now, let&#8217;s move on to the methods for repairing the SQL Server Master Database MDF file.<\/p>\n<h3 class=\"main_heading\"><span class=\"ez-toc-section\" id=\"03_Best_Methods_to_Repair_SQL_Server_Master_Database\"><\/span>03 Best Methods to Repair SQL Server Master Database<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>This section contains all the different methods that will help you to repair or resolve SQL Server Master Database corruption.

You only need to ensure the backup file is created with the SQL Server version where you want to restore it.<\/p>\n<ol>\n<li>First of all, retrieve the database backup of another instance.<\/li>\n<li>Navigate to the Database section of the Database dialog box and rechange the name to repair_masterdb from the master database file. (e,g:- You can rename the database file as recover_masterdb.mdf and recover_masterdb.ldf.<\/li>\n<li>Now, detach the newly created database repair_masterdb file from SQL Server.<\/li>\n<li>After that, copy the database files recover_masterdb.mdf and recover_masterdb.ldf under the file system.<\/li>\n<li>Here, you need to delete corrupted MDF and LDF files of SQL.<\/li>\n<li>Afterward, Rename recover_masterdb.mdf and recover_masterdb.ldf database files as master.mdf and mastlog.ldf.<\/li>\n<li>At last, restart SQL Server again and check whether the Master Database corruption issue is resolved.<\/li>\n<\/ol>\n<h4 class=\"main_heading\"><span class=\"ez-toc-section\" id=\"Method_2_Repair_Master_Database_Corruption_By_Recreating_Database\"><\/span>Method 2: Repair Master Database Corruption By Recreating Database<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>In case you don&#8217;t have the backup of the Master Database file, then you weren&#8217;t able to repair the SQL Server Master Database file using the above-mentioned method.
