Access Database Become Inaccessible On Reaching 2 GB Threshold
In a practical scenario, you may receive the below error message when you run make-table query, append query, or import the data in large MS Access database file:
“Invalid argument.”
After this problem, you can not perform any operation on the database. The database becomes completely unusable and you can not access the data from it. To get your valuable data back, you have to Repair Access database.
Root of the problem
This behavior occurs when Access database's size approaches 2 GB size limit. Microsoft Access (all versions) does not allow you to create a database larger than 2 GB. It not only includes data, but also reports, forms, stored procedures, macros, etc. Increased size of the database may damage it.
Resolution
To sort out this issue, you need to reduce database size. You can reduce the database size by compacting it with Compact and Repair Database tool. Go through the below steps to do so:
Start Microsoft Access.
Select Compact and Repair Database option from Database Utilities on Tools menu.
Select the database that you need to compact in Database to Compact From dialog box, and click Compact.
Select name for compacted MDB or ACCDB file in Compact Database Into dialog box.
Click Save button.
You can also solve this behavior by splitting database into multiple databases. It is possible with 'Database Splitter Wizard' of Microsoft Access application.
If the above methods do not help you fix the problem, because the database is corrupted, restore Access database from the most recent backup. But, in case of unavailability of the backup, access database repair is required to repair and restore the database.
You can efficiently repair the database using third-party Access Repair software. The repair applications ensure absolute and easy recovery in all cases of database corruption as they have interactive and self-descriptive user interface.
access database recovery is the best Access recovery software ever made. It repairs and restores damaged MDB and ACCDB files of Microsoft Access 2007, 2003, 2002 (XP), and 2000. The software restores all damaged Access database objects, such as reports, forms, tables, data types, and constraints.
Repairing corrupt indexes in Access 2007 database
Consider a scenario wherein you are working on an Access 2007 database. There is a power surge and the system shuts down abruptly. You open the database when the power is restored but find that some of the rows in a table are shown as “#Deleted”.
Cause:
The most possible cause of this behavior is that the index has corrupted because of abrupt system shutdown.
Resolution:
To resolve this situation, you should replace the corrupted database with its updated and clean backup. However, if the backup is not updated then you should use the in-built repair utility of Access to repair the indexes. If it still does not help, then you should perform the following steps to recover Access database:
1.Create a query into the table and try to exclude those rows that have been corrupted.
2.Convert it to a Make Table query once you have got the best range of uncorrupted records. You can use it under Query Type on the Query Tools tab in the Access Ribbon.
3.Run the query to create a new table.
4.Delete the old table.
5.Compact the database to remove any pointers to the corrupted table. You can do this by following Office Button | Manage | Compact.
6.Rename the new table as the older one.
7.Recreate the indexes and relationships in the new table. If you are unable to create a relationship, use the Unmatched Query Wizard to identify which records are missing.
This should solve the problem. However, if you are still facing the issue then you should use a third-party Access recovery tool to recover Access database. Such read-only tools are able to recover Access databases by employing fast yet sophisticated scanning algorithms.

Concurrent Modification Results in Corruption of Access 2007 table

MS Access tables have numerous rows and columns containing varied data. These tables are stored on the server so all the users can view updated information saved in the table. Authorized users connected to the server can perform update operation. Though the process of updation is easy, it might result in corruption of table, if two or more users connected to the network perform modification simultaneously on the same table. The records saved in the table become inaccessible once it gets corrupted. In such cases, if the user needs to access the records, then s/he needs to restore the table from an updated backup. However, if no backup is available or is corrupt, then the database user needs to opt for inbuilt ('Compact and Repair') or commercial access repair utilities.
Consider a realistic situation, where you create a table 'Employee' that stores records related to employee name, address, phone number, and salary. The table is saved on the network and is modified as and when required. On a certain day, by chance, two users in the organization updated the records in the table, simultaneously.
Since the updation was performed simultaneously by both the users, it resulted in corruption of the table. In such cases, the data saved in the 'Employee' table becomes inaccessible.
Resolution:
To repair the corrupted 'Employee' table, you need to use an inbuilt repair utility named 'Compact and Repair'. To do so, the user needs to:
1.Choose 'Compact and Repair Database' option after clicking on 'Tools' option
2.Next, click 'Database to Compact From’ option
3.Choose 'Compact' option
4.Lastly, click 'Save' to store the repaired file
In case the above steps fail to repair the table, then the user needs to search for a third-party access database recovery application. Such Access Repair tools use extensive repair mechanisms to repair any MS Access database object.
Access Recovery repairs MS Access databases to the maximum level. Compatible with MS Access 2007, 2003, XP (2002), and 2000, the software safely repairs almost all MS Access database components, including tables. The Access Repair utility can be installed on Windows 7, Vista, 2003, XP, and 2000.
Fixing “Primary index...” Error Post Access Database Damage
To explain the above problem, consider a practical case where you create a table 'Accounts' with ten rows. Now, when you attempt to view the Autoincrement Id for a new record in Accounts table, the table displays less rows. It also displays a difference of rows in comparison to the original Accounts table. Furthermore, when you attempt to update the Accounts table, you encounter the below error message:
“Primary index is not unique”
Cause:
The above behavior occurs when the Accounts table is corrupted.
Resolution:
To isolate the above issue and repair the Accounts table, you will need to run 'Compact and Repair' utility. Below are the steps to use this repair utility:
1.Launch the utility and click on 'Tools' option.
2.Select 'Database Utilities' and click 'Compact and Repair Database' option.
3.Browse to the damaged MS Access database and select 'Database to Compact From’ option
4.Choose 'Compact' and click 'Save'.
Once the repair is complete, the Accounts table comes in reusable form. However, if the error message persists while accessing the Accounts table, then you will need to opt for a third-party access database recovery software. These Access Repair tools scan the corrupted database objects, repair them, and restore the repaired object at user-specified location.
Access Recovery ensures maximum repair of Access database objects, such as, tables, forms, and reports.

Converting Access Database Using DAO Compact Database May Cause Corruption

Are you unable to open your Microsoft Access Database (MDB or ACCDB) after converting the database from earlier version to later version using DAO Compact Database method? It causes unexpected errors while accessing the database and wants you to reconvert the data or import database components to new database. However, this method may not work if the database is either locked or corrupted. In case of corruption, you need to go for access database recovery to work around the data loss problem.
As an practical instance, you may come across the below error message while accessing a Microsoft Access database that is converted from a prior version:
“This database is in an unexpected state; Microsoft Access can't open it. This database has been converted from a prior version of Microsoft Access by using the DAO Compact Database method instead of the Convert Database command on the Tools menu (Database Utilities sub menu). This has left the database in a partially converted state. If you have a copy of the database in its original format, use the Convert Database command on the Tools menu (Database Utilities sub menu) to convert it. If the original database is no longer available, create a new database and import your tables and queries to preserve your data. Your other database objects can't be recovered.”
After the above error message, you come across database inaccessibility and data loss. In order to gain access of your precious data, you need to find out the cause of this problem and perform Access Repair by sorting it out.
Root of the problem
It occurs if you convert an Access database by using DAO Compact Database method, in place of using the Convert Database method. It may also leave your database in corrupted state.
Resolution
You can sort out this problem by any of the below methods:
If you have copy of original database, try reconverting the database.
If the copy is not available, make a new Access database and import database components to newly created database.

Repairing Database Using Jet Compact Utility

MS Access application is one of the most widely used software used to create and maintain databases. The databases created using this application are used for various purposes like accounting, reporting, and more. However, like any other database, an MS Access database can also be corrupted due to various reasons, such as, improper system shutdown, MS Access malfunction, and virus attacks. In most of the cases, MS Access application detects the corruption at the time when the user attempts to mount his/her database. An ideal way to overcome any MS Access corruption situation is by restoring data from an updated backup. But in case the database backup is unavailable or inaccessible, then the user needs to use an effective access repair application.
Three ways to repair a corrupted MS Access database are:
Repair the corrupt MS Access database from the dialog box which pops-up when MS Access detects that the database is corrupted.
Use 'Compact and Repair' option by using below steps:
1.Select 'Tools', and then 'Compact and Repair Database' option.
2.Select 'Database to Compact From’ option, and then click 'Compact' to start compacting.
3.Click 'Save' to save the repaired database.
The user needs to run VBA (Visual Basic for Applications) code used by the Compact Database method.
However, if the database remains corrupted after using the above methods, then s/he needs to use Jet Compact (Jetcomp.exe) utility. This utility is successful because it opens or closes the database before compacting it. However, there is a misconception, that is, if this utility is unable to repair the database, then the database can not be accessed. The truth is that the database can still be repaired and accessed using an effective access database recovery application.
Third-party Access Repair tools comprehensively repair the database when all the above repair techniques fail to perform. The database repair tools employs advanced scanning procedures to perform repair and restore it at the user-specified location. The tool neither deletes nor modifies the original database file.
Access Recovery is one of the most commonly used Access Repair software to repair corrupt database created in MS Access 2007, 2003, XP (2002), and 2000. The database repair application allows the user to preview the repairable file before storing. The tool is designed for Windows 7, Vista, 2003, XP, and 2000 operating systems.
