Max Jordan | March 22th, 2017 | MS Access Database



Microsoft Access is one of the most efficient database management system developed by Microsoft. Complete data in MS Access are stored in the MDB and ACCDB file with file extension .mdb/.accdb depends on the Microsoft Access version. Sometimes if Access is not handled properly, corruption chances increases. The user might not able to access files stored on there system.

Here, we are going to discuss Microsoft Access database corruption issues and its prevention. Before, coming to this, let’s see what are the most common MS Access database corruption errors messages:

  • ‘Unable to open database mydb.mdb’
  • ‘Unrecognised database format’
  • ‘Microsoft Access recognized corruption in file’
  • ‘MDB is not a datbase’
  • ‘Cannot open a form or report’
  • ‘Error accessing file. Network connect may have been lost’

These were some common errors. Now, coming back to causes MS Access database corruption or corruption issues in Access database.

Causes of MS Access Database Corruption Issues:

Access database can be corrupted due to number of factors. Some of them are:

  • Hardware Failure: Hardware issues affects the database integrity. Microsoft Access is very sensitive towards hardware failure. As a result, if MS Access crashes the jet database immediately terminates. Due to termination of the database, writing is stopped before finishing. This causes MS Access database corruption.
  • Software Conflicts: While using any third party controls for MS Access, one should ensure that these third party controls are from trusted source. If due to any reason these plug-ins crashes, will affect database too.
  • Multi-User Access: While sharing a database with multiple user, jet engine plays a very important role. For sharing files with multiple user Jet engine uses lock files(.ldb) which synchronize read/write database. And these lock files completely depend on Wins OS API call to handle synchronization which depends on file transfer (network) protocols. Multiple transfer of data over the same network may slow down jet communication. Due to slow down or sometime due to network issues it is left to ‘suspect’ mode due to which corruption may occur.
  • Jet engine and MS Access Bugs: Various corruption occurs due to bugs in the software. One of the well known bug is ‘Name Auto Correct’ which despite of solving problem, causes most of the problems which result in Microsoft Access database corruption.
  • Slovenly Database design: Design for multiple user to share data over a network increases extra file size bloating. This resulted lot of pressure on network and which increase the risk of data corruption.

To prevent these type of data corruption one should follow some major rules which will help to keep Access database free from corruption.

Ways to Prevent Corruption in Microsoft Access Database

We need to keep things away by which Access database gets corrupted. So below we will discuss how to prevent Microsoft Access database corruption:

  • All networking accessories and hard drive should be checked on the regular basis to prevent MS Access corruption.
  • Multi-Users should be restricted as much as possible or one can share database by using split database method which will decrease load on server.
  • No 3rd party plug-ins should be used unnecessary.
