Author: Filegroups in Microsoft SQL Server are primarily used to group database files to use them in an easy and simple way. A system administrator can create particular filegroups for each hard drive attached in the system and assign tables, indexes, text from a particular table to them. While these filegroups can be easily accessed, the possibilities of their corruption always remains. In such situations, the best way to access the data is by restoring it from an updated and valid backup. However, in case of no backup availability or backup failing short of restoring the desired information, then you will need to use advanced SQL Repair software that can completely repair your corrupted database and recover its components.
Consider a practical instance, where you receive the below error message when you attempt to open your SQL Server database:
“Unable to process index I_NAME of table O_NAME because filegroup F_NAME is invalid.”
Cause:
The root cause for the occurrence of the above error message is that filegroup Ids stored in the metadata for an index do not exist, so that index can not be checked.
Resolution:
Below are certain resolutions that enable you to resolve the above error message:
Error 2522 could be a result of hardware malfunction. In this case, you will need to check your computer system, Windows error logs, and SQL server. To resolve the hardware problem, you will need to swap the old hardware components with new hardware components.
However if the error message is not occurring due to hardware problems, then you can restore the database from an updated backup.
But if in case, you have not maintained any backup, then you will need to execute the DBCC CHECKDB command to repair the corrupted database.
In most cases, the above resolutions resolve your issue and your SQL database becomes accessible. But, if all the above resolutions fall short and the error message still remains, then you will need to use advanced SQL Recovery application that can repair your corrupted database. Such SQL Repair tools use high-end scanning methods to repair the corrupted database. Built with highly interactive user-interface, these tools are easily understandable without any prior technical knowledge.

In Microsoft SQL Server, you can import or export data through Import/Export Wizard. This wizard offers simplest way to create an Integration Services package, which copies data from a source to destination. The MS SQL Server Import/Export Wizard could copy data from and to a data source for which a native OLE DB provider or a managed .NET Framework data provider is available. Microsoft Excel is one such application. But sometimes, after importing data from Excel spreadsheet, the database may not be accessed. This behavior can occur due to corruption and lead to critical data loss situations. At this point, you need to opt for SQL Recovery solutions to retrieve business-critical data from damaged database.
In a practical scenario, when you try to open a SQL Server database after importing data from an Excel spreadsheet that was originally created using data from SQL resultset, following errors may occur and prevent you to access the database:
“The component has detected potential metadata corruption during validation.
Error at Update Counterparty Table with new counterparties [DTS.Pipeline]:
The package contains two objects with the duplicate name of ‘output column’”
And
“It may not be possible to recover to a valid state using a component-specific editor. Do you want to use the Advanced Editor dialog box for editing this component?”
When this issue occurs, MS SQL Server database become inaccessible. In order to sort out this problem, you need to find out the cause of this issue and go for SQL Repair by resolving it.
Root of the issue
As stated in above error message, this problem occurs due to metadata corruption in SQL Server database. SQL Server use a number of metadata for effective management of database. The metadata are used for easily accessing data from database. When they gets damaged, SQL Server can not find the required data and thus you come across data loss situations.
To retrieve data in such scenario, repair and restore damaged database through third party SQL Recovery applications. These software are particularly designed to thoroughly scan the affected database and retrieve all of its damaged and inaccessible objects such as stored procedures, triggers, tables, reports and forms. These tools are completely safe and easy to perform SQL Repair in all database corruption circumstances.
SQL Recovery is the best ever made and the most advanced application that repairs and restores all of the SQL Server database objects. It supports recovery from Microsoft SQL Server 2008, 2005 and 2000. This software is compatible with Microsoft Windows Vista, 2003, XP, 2000 and NT.

Microsoft SQL Server is the most powerful and advanced RDBMS (Relational Database Management System), which offers excellent database solutions for all sizes of organizations. It provides several distinct and extraordinary features for effective management of your business-critical data. All of your valuable data is stored in MDF (Master Database File) in the form of tables. Although, SQL Server is considered as most reliable database management system, but in some situations the MDF file may become inaccessible and you come across serious data loss situations. In such critical situations, you need to opt for SQL Recovery solutions to get your lost data back.
In a practical scenario of MDF corruption and data loss, when you attempt to open MS SQL Server database by double clicking the file, you encounter below given error message and the file could not be opened:
“Msg 945, Level 14, State 2, Line 1
Database ‘database name’ cannot be opened due to inaccessible files or insufficient memory or disk space. See the SQL Server error log for details”
This error message renders whole database inaccessible and you can not use your business critical data from it. At this point, to gain access of your valuable data, you are required to find out the cause of this behavior and perform SQL Repair by resolving it.
Cause
This problem generally occurs due to corruption to MS SQL Server database. The MDF file is corrupted and SQL Server can not read its contents. Data corruption might occur due to virus infection, improper system shutdown, inappropriate database references, application faults, missing system files and faulty memory.
No matter what the cause of this problem is, the most significant thing that you should consider is your critical data. Data loss can not be accepted at any cost and thus it is merely essential for you to repair and restore damaged database.
Resolution
To sort out this problem, check SQL Server error log. Make sure that location of MDF and NDF files and confirm that you have sufficient permissions to access database. Also check free disk space on drive, which contains database.
When all else fails to fix this issue, SQL Recovery is the only option to retrieve data. This is best possible using third party applications. These software perform extensive scan of affected database to retrieve all of its objects and stored data. The SQL Repair software are quite easy and safe to use.

Microsoft SQL Server is the most advanced and widely used RDBMS (Relations Database Management System). It stores all of your critical data in MDF (Master Database File), in the form of tables. But in case if the SQL Server gets damaged, it does not allow you to properly mount the database and access data from it. There are several possible scenarios of SQL Server corruption, which include virus infection, application crash, improper system shutdown, file system corruption and operating system failure. All these situations cause critical data loss and require SQL Recovery to be sorted out. You should always opt for reliable and effective solutions for absolute recovery.
As as example of SQL Server corruption, when you try to start Microsoft SQL Server 2005, you might encounter below given error message:
“Could not start the SQL Server (SQL2005) service on Local Computer
Error 14001: This application has failed to start because the application configuration is incorrect.
Reinstalling the application may fix this problem.”
Subsequent to above error message, MS SQL Server database become unmountable and inaccessible. The major reason behind occurrence of above error message is damaged or incorrect SQL Server configuration settings. In order to access database in these cases, you need to reinstall SQL Server 2005.
Although, reinstalling SQL Server might help you to carry out SQL Repair, but it is not safe at all. When you reinstall the application, data loss might take place. After you reinstall the SQL Server, the database might get damaged and it can not be reattached with the server.
The problems might occur due to SQL Server edition mismatch. MS SQL Server is available in 64-bit and 32-bit editions. The 64-bit edition uses Windows Installer to perfectly integrate installation of SQL Server characteristics in single feature tree. But if the hardware is not compatible with particular edition, the installation might fail.
No matter what the cause is, database corruption can not be accepted at any cost and it cause serious data loss issues. In these cases, you need to repair and restore the damaged database and retrieve all of its objects using third party SQL Recovery software.
These applications are particularly designed to perform in-depth scan of affected database and successfully restore it. The SQL Repair tools have interactive and simple graphical user interface to enable Do It Yourself recovery. With read-only and non-destructive conduct, they are completely safe to use.

Microsoft SQL Server is the most popular and advanced Relational Database Management System (RDBMS), which is developed and marketed by Microsoft Corporation. The SQL Server enables you to use the T-SQL (Transaction Structured Query Language) to carrying out database transactions. T-SQL can be created to effectively manage SQL Server and to prevent unauthorized access of the database. SQL Server stores all of the data in MDF (Master Database File) in the form of several different tables. In some situations, these tables might get damaged and thus become inaccessible. This behavior of MS SQL Server cause critical data loss situations and require SQL Recovery to be sorted out.
Due to the advanced features, which SQL Server offers, there are several organizations who use it for effective management of their databases. But your decision of use the MS SQL Server might prove wrong when you can not get access of your mission critical data. In some situations, when you attempt to access the SQL Server database, you come across below given error message:
“Server can’t find the requested database table”
After this error message, you can not access the require database table and thus face data loss situations. In these cases, to get your mission critical data back, you need to sort out this issue by performing SQL Repair.
Grounds of the issue
The major reason behind the occurrence of this error message is corruption to the SQL Server database. The database might get damaged due to a wide range of reasons such as improper system shutdown, virus infection, application errors and many alike.
If the SQL Server database, which has got damaged, isn’t so complicated and does not contain huge amount of data and objects, then you can rebuild the database easily. However, if the database is very large and complex, then you will have to go for SQL Database Recovery to retrieve data from damaged database.
The recovery is best possible with the help of powerful and advanced third party applications, which repair and restore damaged database. The SQL Repair applications carry out thorough scan of the damaged database and retrieve all of the data from it. With self-descriptive and interactive users, these applications are completely easy to use. These tools are completely safe as they have read only and non destructive conduct.

In SQL Server storage space is divided into pages, numbered sequentially. Each database page has a type that defines the type of data that is contained in the page, for example an index page or a data page. If any of these pages gets corrupt, SQL Server reports errors. You can detect this corruption by running DBCC CHECKDB command. However, to recover from such data loss, you will need to use your backup to restore. But if no clean backup is available at the moment, you should use SQL Recovery software.
At times, when you run DBCC command to check the consistency of your SQL Server database, you might come across the below error :
“Msg 2503, Level 16, State 1 Table Corrupt: Page linkage is not consistent; check the following pages: current page#=xxx; page# pointing to this page=yyyy; previous page#=zzzz”
Cause
Error 2503 might be encountered due to any of the possible reasons:
You are not running DBCC in single-user mode and some updates are running
Table data page or index page is corrupt
Solution
To solve the problem, discussed above, you need to apply these methods:
Make sure that you run DBCC in single-user mode
If you are using the command in single-user mode, you need to check for a valid data backup to restore the lost data
If you don’t have any good data backup, use DBCC PAGE command to find out whether the infected page is a data page or an index page
To fix index corruption, you should drop and then recreate the index of the table
You need to copy all the database objects and data to a new database if the data pages are affected. You might fail to copy corrupted tables. Drop the old database
If applying the above measures doesn’t help, you should use third-party SQL Repair utility to safely repair and restore the damaged database and its objects. SQL Recovery software apply powerful scanning algorithms and retreive data while maintaining their intactness.

Article Source: How to Resolve Error 2503 in SQL Server?
Microsoft SQL is a relational database management system that is widely used in organizations to store data for customers and for accounting etc. MS SQL Server database is designed around the tables, each having several columns. SQL Server uses MDF file to save the records, views, triggers, primary keys, foreign keys, indexes and other SQL database components. But at times, operating system errors and hard drive failure like events might prevent you to access this file containing various records and other related information.
SQL server data loss can occur at a number of different levels. The first level of data loss starts with the storage device. The next level of data loss starts with the file system level. The information about where data files are on the volume can also get damaged or corrupted. The last level of data loss can occur within the file itself as the MDF files are prone to corruption because of its complexity. The internal structure can get corrupted at any point of time and makes the table data inaccessible.
Everyone knows the fact the data that resides inside an organizational database is valuable. For the smooth functioning of the organization, information stored in SQL server is so crucial that SQL server or SQL database corruption compel every organization to find out the solution that helps in getting back the data stored in the SQL server.
Common MS SQL server error messages pops up when the database records containing MDF file gets corrupted:
“Server: Msg 8942, Level 16, State 1 Table error: Object ID O_ID, index ID I_ID, page P_ID. Test (TEST) failed. Slot S_ID, offset 0xADDRESS overlaps with the prior row”
“Server can’t find the requested database table”
“The file *.mdf is missing and needs to restore”
“Index ‘%ls’ on ‘%ls’ in database ‘%ls’ may be corrupt because of expression evaluation changes in this release. Drop and re-create the index”
“The process could not execute ’sp_replcmds’ on server”
“Server can’t find the requested database table.
“The conflict occurred in database ‘db_name’, table ‘table_name’, column ‘column_name’. The statement has been terminated’
“Internal error. Buffer provided to read column value is too small. Run DBCC CHECKDB to check for any corruption”
These error messages are indication of data loss, if timely and appropriate measure is not taken. One can restore the information from the latest database backup. But sometimes, it is not feasible to restore complete information from the backup.
At this point of SQL corruption, many SQL recovery software’s are widely available, the only need is to find the tool that is cost effective, reliable and result oriented.
After performing wide market analysis, I come across SQL recovery software, one of the renowned software designed to recover SQL database components that includes triggers, records, views, table data, primary keys and every other SQL database component. I downloaded its free to evaluate version and performed SQL recovery process. The SQL recovery with this process is extremely easy that can be performed easily by anyone.
I would like to suggest SQL database recovery software in the time of SQL database corruption crises as this tool is best in all the aspects including cost effectiveness, recovery percentage, reliability and simplicity.

All the SQL database files are split into PFS intervals, where PFS stands for Page Free Space. A PFS interval is about 64 MB in size and has 8088 pages in it. Each PFS page has a byte-map with one byte per page for all the pages included in the PFS interval. At times, you get database errors that indicate that a page exists with invalid type in its PFS page. Database corrupted in this way needs to be restored from backup. However, if you don’t have any valid data backup available, you need to use advanced SQL Recovery application.
For an instance, you might come across the similar error message with your SQL Server database:
“Database error: Page P_ID1 is marked with the wrong type in PFS page P_ID2. PFS status 0xVAL1 expected 0xVAL2.”
This error is marked as error 8948 in SQL Server error log.
Cause
The above error results when a page P_ID1 has been marked with incorrect type entry in PFS page P_ID2. As described above, each PFS page has a byte-map with one byte per page for all the pages included in the PFS interval. Among rest of the information, each byte contains three specific type of status bits that define the page type:
(0×10) for PFS_IS_IAM_PG
(0×40) for PFS_IS_ALLOCATED
(0×20)for PFS_IS_MIXED_EXT
Error 8948 occurs when these bits are improperly set.
Solution
You need to deploy these measures to cope up with such issues:
If such kind of problems are persistent in nature, you should check the system for possible hardware problems first. You can do so by examining the error log reports of Windows, SQL Server™ and application.
Check the database backup status. If complete and valid, delete the damaged database and restore from the backup.
Without using any repair clause, execute DBCC CHECKDB to determine the required repair clause to be applied. Next, run DBCC CHECKDB with this repair clause.
If you desire to prevent data loss that might occur due to the above step, you need to use advanced SQL Repair tools. These are safe SQL Recovery software that can scan a corrupted database and restore it successfully.

SQL Server uses index information so that if you process a query that could fetch quick results. These are created on table columns. An index is basically comprised of various pages, arranged in the form of a B-tree structure. So, as you execute a query, the engine starts navigating from the root node and continue through the intermediate nodes till the leaf node is reached. Any malfunction in this index structure might introduce table corruption errors. Such situations require you to restore the data from backup or use SQL Repair utilities that could repair the database and its components effectively.
You might encounter the below table error with your SQL Server database:
“Table error: Cross object linkage. Page P_ID1->next in object ID O_ID1, index ID I_ID1 refers to page P_ID2 in object ID O_ID2, index ID I_ID2 but is not in the same index.”
This error is marked as error 8982 in SQL Server error log with severity level 16.
Cause
An SQL Server table results the above error if the two pages (P_ID1 and P_ID2) have been marked with dissimilar index and/or object information though they have been marked as linked.
Note: If you observe these problems persistently occurring, the possible reason is hardware malfunction.
Solution
Such table corruption errors should be resolved by following these methods:
First, you need to analyze your system for possible hardware problems. You can deduce such problems through error logs of operating system, application and SQL Server™ . Try to fix such problems, if any.
If you have valid data backup available, you need to restore your lost data from it.
If issue persists because of unavailability of clean data backup, you can run DBCC CHECKDB command that will let you know the exact repair clause that could fix this corruption. Execute DBCC CHECKDB command using the recommended repair clause.
Applying the above measure can cause data loss. Thus, for better and safe SQL Recovery, you should use third-party tools to scrutinize and repair damaged SQL Server databases. SQL Repair applications are built with powerful technology to assist database recovery in each possible case of corruption.

RAID servers are considered as the most trusted and reliable storage medium. But sometimes, they may also lose all the hard drives, which include your important data, backups and other information.
Most of the organizations use RAID for storing their important SQL Server databases. When they fail, generally you may lose all of your data, but sometimes you may get some traces of data and can recreate the database.
In such situations, you can save your database by restoring the database from your backup. But unfortunately, when you try to restore backups, which were made through MS SQL Server for a database, which is running on DTP SmartRAID V controllers, you may receive the following error message:
“Msg 3270, Level 0, Sev 16.
An internal consistency error occurred. Contact Technical Support for assistance.”
In this case, when you attempt to detach the database using sp_detach_db stored procedure and then attempt to attach the database again with the help of sp_attach_db stored procedure, you may get the flowing error message:
“Server: Msg 5172, Level 16, State 15, Line 1.
The header for file ‘d:\pubs.mdf’ is not a valid database file header. The PageAudit property is incorrect.”
After this error message, the restoration process gets halted and you can not access anything from your SQL Server database.
Grounds of the trouble
As stated in the above error messages, this problem is either due to inconsistent state of the database or due to invalid header entry for the database. In both of these cases, the database may get damaged and thus even a single bit of data can not be retrieved from it.
In such disastrous situations, you need to perform SQL recovery to repair the damaged database and retrieve all of your data from it. SQL recovery can be carried out using the MDF recovery software.
MDF recovery software are easy to use tools, which allow you to have quick and trouble-free MDF repair in each and every case of MDF corruption. To ensure complete and successful SQL repair, always use effective SQL recovery software like Stellar Phoenix SQL Database Recovery software.
