Here is the list of some noticeable features of MS SQL Recovery software:
- Supports recovery of unreadable MDF file: The software supports recovery of highly corrupted or damaged MDF files of Microsoft SQL Server. It ensures users maximum possible recovery of corrupted MDF files within a couple of minutes.
- Supports selective recovery: The software allows you to perform selective recovery of data and file objects of corrupt MDF file. You can select any specific file object that you want to recover, and save it to a new file.
- Supports recovery of NDF files: This tool can also read your remaining corrupt data of an MDF file from its NDF files. NDF files contain some part of data of your MDF file. The software is designed to automatically detect the data of an MDF file from multiple NDF files available on your system.
- Restores tables and other components of MDF file: The software is highly efficient to restore maximum tables and other file components of the corrupted MDF file. It recovers all the tables, such as: system tables and user tables along with other components, such as: views, programmability, triggers, default, store procedure and function.
- Supports preview of recovered data: By using this software user can see the preview of recovered data of corrupt MDF file, such as: user tables, system tables, views, triggers, store procedure, default, function, etc. By clicking on a particular table you can see all the recovered content in the Preview Pane.
- Highly supportable and compatible: The software supports recovery of corrupted MDF files which are originally created by using MS SQL Server 2000, 2005 and 2008 and higher versions. It is highly compatible with all major versions of Windows Operating Systems, such as: 2000, 2003, 2008, XP, Vista, or Win 7 (32-bit or 64-bit) and Win 8.
- Easy-to-use application: It is an easy-to-use application therefore, no technical skill is required to use this software. Any technical and non-technical user can easily use it. The software consists of a self-describing user interface that helps users throughout the recovery process.
- Supports two modes of MDF file recovery: The MDF file recovery can be executed in two recovery modes by using this software:
- Standard Mode: Standard Mode of recovery is to repair an MDF file if the corruption is minor, i.e. not extremely corrupted. This recovery mode takes very less time to fix corruption from MDF file.
- Advanced Mode: Advanced Mode of recovery is to repair an MDF file if it is extremely corrupted. Users are requested to use this recovery mode if Standard Mode fails to recover data from corrupted MDF file. This may take a few more minutes since it scans the corrupted MDF file thoroughly.
- Save as SQL Server Database: By this option user can save the recovered data in an SQL Server Database.
- Save as SQL Scripts: By this option user can save the recovered data in SQL Scripts.
- Export only schema: If a user wants to export only the schema, then Export only schema will be helpful. This option creates only schemas for the selected tables and other components of the MDF file.
- Export data and schema: If a user wants to export the data along with the schemas, then Export data and schema will be helpful. This option exports all the data and schema for the tables and other components of the MDF file.
Q. What are the most common errors which may take place at the time of MDF file corruption?
Ans. Here is the list of some most common errors which may take place at the time of MDF file corruption:
- Nonrecoverable I/O error occurred on filename.mdf.
- Index File is Missing or Corrupt.
- Missing or Invalid Key in Index.
- The filename.mdf is missing and needs to restore.
- Error: 824, Severity: 24, State: 2.
- Error 2502: "Corrupt Table".
- Filename.mdf is not a primary database file (Microsoft SQL Server Error: 5171).
Q. What types of applications can I build with Microsoft SQL Server?
Ans. With Microsoft SQL Server you can build several Windows applications, such as: Microsoft .NET Framework, Visual Basic (VB) for applications including Microsoft Access & Microsoft Excel, .NET Web Services. The Microsoft SQL Server is also useful as a back-end database for multiple applications, like: SharePoint Server, Microsoft Dynamics CRM (Customer Relationship Management), Microsoft Project Server, etc.
Q. What are the various options to save the recovered output of MDF file?
Ans. SysInfoTools MS SQL Recovery software offers various options to save the recovered output of MDF file:
- Save as SQL Server Database: The saving option Save as SQL Server Database allows you to save the recovered output automatically in your SQL Server database. You need to enter the name of the server in the Server name box and the name of the database in the Database box. Then you need to choose your Authentication, either Windows Authentication or Server Authentication. If you want to select Server Authentication, then you need to enter the Username and Password. In case of Windows Authentication, there is no requirement for any username and password.
- Save as SQL Scripts: The saving option Save as SQL Scripts allows you to save the recovered output in SQL scripts. A set of SQL commands are saved in SQL scripts and you can save them at any of your desired location.
- Export only schema: The Export only schema option allows you to export only the schemas of the selected tables from the recovered MDF file.
- Export data and schema: The Export data and schema option allows you to export data as well as schema of the selected tables from the recovered MDF file.
Q. How does an MDF file of Microsoft SQL Server get corrupted?
Ans. MDF or Master Data file is a database file format used by Microsoft SQL Server and this file contains schema and data. Sometimes an MDF file of Microsoft SQL Server gets corrupted due to various unforeseen reasons, such as:
- Virus infection: Virus infection or virus attack is one the most common reasons for file corruption. It may harm computer performance or sometimes its data. The MDF database files of Microsoft SQL Server are not immune from virus corruption. They can be easily infected or corrupted by virus attacks.
- Storage media corruption: Storage media corruption means the media where the files are stored gets corrupted or malfunctioned due to any specific reason. Suppose your MDF files are stored in an external storage device and it gets corrupted or damaged. All the files which are stored in it will become inaccessible or corrupted.
- Abruptly system shutdown: Another common reason of file corruption is abruptly system shutdown. Sometimes this can be taken place due to sudden power outage or sometimes intentionally. For example: while working on SQL Server if your system gets turned off itself due to sudden power failure or if you turn it off abruptly, then the opened MDF file may become corrupted or invalid.
- Network failure or weak internet connection: Network failure refers to a situation when any component of your network fails or you are having a weak internet connection. A good network connection is very important for attaching an MDF file to the SQL Server. While attaching an MDF file to the server if your network connection fails, then this may corrupt your MDF file.
- Software collision or malfunction: Sometimes your SQL server application may collide with other software applications, which are installed in your system. This may result in software malfunction and damage its files.
