Many of you might have used Access Database in your organization and know about its proprietary Database Management System. Then you might be aware of the fact that just like other files, MDB files are also prone to corruption, which can drastically affect other database files. But how does an MDB file gets corrupt if you have not moved the data here and there? That’s what we’re going to talk about in detail. Let’s first know the reasons for MDB file corruption.
What are the Reasons Behind MDB File Corruption?
Well, there could be multiple reasons behind the corruption of MDB files, some of the main reasons include:
- Interrupted change in data due to network loss. In such cases, the file can be repaired, but some of your data might be missing after it.
- Hardware failures are another reason behind MDB corruption.
- If you make frequent edits to Memo fields, the chances of Access database corruption increases.
- When a corrupted file is used by Access Database, the infection will spread to the entire database.
- Due to improperly designed third-party plugins installed on your system.
Error Messages When MDB Gets Corrupt
When your Access Database gets corrupt, you can receive the following error messages on your screen:
- Unrecognized Database Format 'filename.mdb' (Error 3343)’.
- The database 'filename.mdb' needs to be repaired or isn't a database file (Error 2239).
- Do you want Microsoft Office Access to attempt to repair the database?
- The Microsoft Jet database engine could not find the object 'xxxx.' Make sure the object exists and that you spell its name and the path name correctly (Error 3011)
- Record(s) cannot be read; no read permission on 'XXXX' (Error 3112).
- Cannot open database 'filename.mdb.' It may not be a database that your application recognizes, or the file may be corrupt (Error 3049).
- Invalid field data type (Error 3259).
- Microsoft Access has detected that this database is in an inconsistent state and will attempt to recover the database. During this process, a backup copy of the database will be made, and all recovered objects will be placed in a new database. Access will then open the new database. The names of objects that were not successfully recovered will be logged in the “Recovery Errors” table (Error 9505).
- The database cannot be opened because the VBA project contained in it cannot be read. The database can be opened only if the VBA project is first deleted. Deleting the VBA project removes all code from modules, forms, and reports. You should back up your database before attempting to open the database and delete the VBA project (Error 29081).
These are the common errors that you might encounter when your MDB files get corrupt. However, there are many other errors that can occur when your MDB file is corrupted.

- Get all the required permissions: Make sure that you have administrator permissions to run the compact and repair database operation. If you don’t have necessary permission, contact your organization’s Global Administrator.
