  • Virus/Malicious Software: Many softwares such as Trojan will corrupt the database. Infected files may be lost or overwritten and make them inaccessible.
  • Interrupted Write Operations: If a database is open and writing the data and suddenly closing the application incorrectly without saving the changes may corrupt the database.
  • Faulty Networking Device: If the database reside on server, then client computer tries to access it via network links. If the interface card, routers, hub or any networking components having problem, then the MDB files may corrupted.
  • Power Failure: Unexpected Shutdown or power failure while you are accessing the database, may leave your files damaged.
  • Mismatch Versions of Jet Database Engine: If you run different versions of Jet Database Engine in your environment, you can also cause corruption of Access Database. Because different Version of Jet write to the database differently and therefore can be the cause of database corruption.

Indication of Damaged Access MDB Database Files

When the database respond the queries in an unexpected and abnormal behavior, it shows that it is corrupted. Damaged databases shows various error messages and leaves us with the need to repair corrupt Access MDB file. Common error messages of corrupted database are listed below:

  4. Unexpected Error
  5. The database ‘filename.mdb’ needs to be repaired or isn’t a database file
  6. Microsoft Access has detected corruption in this file.

Methods to Prevent Access Database Corruption

‘Prevention is better than cure’. Before the database gets corrupted, user should use following given measures, preventing it from getting damaged, also avoiding the need to repair corrupt MDB files.

    • Avoid dropping network connections.
    • Avoid incorrect termination of Jet Database connection such as loss of power during database writes, manual shutdown or allowing the Task Manager to shut down the application, so on.
    • When you are programming, close all ADO or DAO objects that you have open. Examples include Recordset, QueryDef, TableDef and Database Objects.
    • Fatal error always cause abnormal termination. If your database prone to fatal errors, you must resolve the errors before the database get too damaged to open.
    • Use the Compact and Repair utility often.
    • Avoid a large number of Open/Close Operations in a loop.
    • Do not run IPX on your Windows NT Server where Jet databases is located across the network and the client id Windows 95 with IPX/SPX. Instead run TCP/IP on Windows Server and a dual protocol stack of IPX and TCP-IP on the Win95 client.
    • Don’t leave the database open for too long time.
    • Take a close look at your virus checking software. Scan anything that comes come into your network before letting it loose on your users.
    • Rather on sticking every object your databases uses in one massive MDB File, Split the database the front end and back end.

Methods To Recover MDB File

Try the below given guidelines to recover your damaged Access database. If the corruption is left untreated then it is likely to worsen in a short period of time.

      • Backup the Corrupt file: The repair utilities can sometimes have an adverse affect on treating the corruption, if the corruption level is high. Hence, it is better to have the backup of the corrupt file as soon as possible before treating it.
      • Delete .LDB File: When an Access Database is opened, another file is created with .ldf extension. The .LDB file is used to determine which records are locked in a shared database and by whom. It is created with the same name as the corresponding database(.mdb).
      • Run the Compact and Repair Utility: To run this utility, follow the below given steps and recover MDB file:

If the Compact and Repair does not work, message will be received of stating so. It means that damage is so severe that it cannot be repaired.

Note: If the above methods is failed to recover data from MDB file, then create new database in MS Access and import the objects one by one, from the old database to new one. Then create the new relationships. This method resolves problems with damaged system tables in the database.
