MS Access is a professional Database management system software, used to gather data, collect and save databases and export reports. It helps to analyze large amounts of data and manages data more efficiently in comparison to MS Excel. The databases, if not maintained properly, can lead to corruption. Due to this, the databases can become unusable and could experience random errors.

Causes for Database Corruption

A few reasons for database corruption are outlined below:

  • Firmware Issues
    A faulty network card can lose packets, and a defective disk drive with bad sectors are the leading contributor to database corruption. MS Access can crash due to hardware issues. The Jet database is also susceptible to crashes. In the event of system crashing the Jet, the database terminates any writing. This is not the case with an SQL server.
  • Plug-in software issues
    Using Add-ons and plugins from unverified sources can also result in database corruption. It is to note that third-party plugins are programs too and run in the same memory space where MS Access does. If the plugin crashes, so do the MS Access.
  • Jet Database version conflicts
    Till data jet Database Engine (DBE) has released four software versions. It is possible that the two users sharing the same datasets have different Jet DBE versions, there is a possibility that database corruption can happen.
  • Bandwidth limitations
    Unlike SQL (client-server based) Jet DBE is file-based and uses a lock file (.ldb) to synchronize database read/write allowing multiple users to share the same file over the network. These lock files rely on Windows OS API calls which further builds on file-transfer protocols. It is common knowledge that all network connections are bandwidth limited. If any software on your machine is using the same channel, then it slows down Jet communication. When this happens connection times out, and database is left in a Suspect state leading to corruption.
  • Bugs
    Like every other tool, MS Access has a few bugs. The Name Auto-correct feature is known to have some issues and can lead to data corruption.
  • Ineffective Database Design
    Access is known for causing file size bloating. This, in turn, severely affect any network protocol increasing the risk of data corruption.

Following are Some of the Most Common Errors that one Encounters in MS Access:

  • MS Access Error 3112: MS Access user is unable to read the records
    MS Access Error 3112
    MS Access error 3112 occurs when a user doesn’t have the permission to read the tables and view their data, or due to corrupted data, MS Access supposes that user doesn’t have the permission to read the specific data.

    In case the user doesn’t have the read permission, then it is advised to consult the system administrator to change the permission settings. If user has the read permission, then it is required to fix the corrupted data by following any of the procedures mentioned here.

  • MS Access Error 3800: MS Access user can’t find the index in the table
    MS Access Error 3800
    MS Access error 3800 occurs when the index gets damaged, and MS Access is not able to trace it. In error, ID or AOIndex refers to the index of the hidden system table.
  • MS Access Error 2239: The database is required to be repaired, or it’s not a Database file
    MS Access Error 2239

    MS Access error 2239 occurs when the jet engine is not able to identify its structure and definition due to some corruption in the data of the table or its definition. This situation can be a result of abrupt MS Access closure.

  • MS Access Error 3011: Microsoft Jet Database engine is unable to find the object
    MS Access Error 3011

    MS Access error 3011 occurs either when MS Access software is not installed correctly, or there is change in Windows registry due to MS Access-related software update. It can also occur due to malware or virus intrusion in Windows system files.

  • MS Access Error 3049: Cannot recognize Database Format
    MS Access Error 3049
    MS Access Error 3049 occurs due to damaged page structure of the MDB file or due to torn definition page or any other element of the Access database. It can also be a result of improper MS Access closure, virus intrusion in system or modification of aspects of MS Access database.

Some General Solutions for MS Access Issues

Though MS Access in conjunction with its Jet Engine tries to fix such errors automatically, there are some errors that need manual recovery. Here is a list of some standard solutions for MS Access errors.

  • Solution for MS Access Error 3112
    Inbuilt programs like Compact and repair tools can be found in the MS Access database and should be used if you encounter this error.

    1. One can use the inbuilt Compact and Repair tool as explained in the previous method
    2. Try creating a new database and then import all the objects such as tables, forms, queries, and reports.
    3. Open the corrupted Access database and manually export every object to the new Access database. One can use the Export tool available in the Ribbon bar. This option is not practical is that you have a large quantity of objects.
  • Solution for MS Access Error 2239
    One can try converting Access MBD file to ACCDB file. Firstly, close the opened Access database file. Follow the steps outlined below to get started:

    1. Go to the File tab and click Open.
