What are the Causes of Corruption in ACCDB Files and How You Can Fix and Avoid them?

There can be many reasons behind a corrupt ACCDB file. In this article, we will explore some common causes and share simple and quick ways to fix ACCDB files. First, an MS ACCDB is a database with data in the form of tables, fields, and other custom forms. It is created by Microsoft Access 2007 and later. When there is corruption in the MS database, the ACCDB files (as well as MDB files) become inaccessible. The problem can be either in the software or hardware.

Common Corruption Causes and Solutions

Hardware Issues: a hardware failure or breakdown is one of the most common reasons behind a corrupt ACCDB file. The problems arise when your ACCDB file is stored in hardware that is:

  • Out-dated
  • Overused
  • Contains bad sectors

As a result, you can face a hardware crash. This causes your MS database and its files to get corrupt.


First, keep your hardware updated to avoid any issues. Secondly, make sure your hardware has sufficient space.

Software Issues: another common reason is software failure. The problem can yield from trying to recover a file system improperly. Other issues may include:

  • Resource conflict on an ACCDB file
  • System corruption


If you feel something is wrong with your software, reboot the program.

Database Issues: An ACCDB file can also get corrupt as a result of a problem in the database;  User Limitation: MS Access database has a user limitation. If more than one user tries to access the ACCDB file simultaneously, the file may get corrupt; Inefficiency: If you don’t monitor the coding of your MS Access database, it will affect the efficiency of the database. As a result, your ACCDB files will get corrupt.


Make sure multiple users aren’t using the file at the same time.

Malware& Virus: Viruses and malware can also corrupt the MS Access database and its files. Today, viruses have advanced. Their algorithms and codes are more intricate and damaging. It is hard to fix ACCDB files that get corrupt with viruses.


Always use an updated antivirus to avoid this problem.

Accidental Shutdown: A power failure, sudden system shutdown, or system overload can corrupt your MS Access database. If your ACCDB file is open, this can result in corrupt files.


Always check that your computer is connected to a power source. To avoid database file corruption it is recommended to back up your Microsoft Access Database using a Hosted Virtual Desktop. Learn more about it from Apps4Rent.
