In this article, we will discuss a few methods, which can help you to get out of the tough situation, the reasons behind Access database files getting corrupt, and all the possible measure you can take to avoid the worst to happen.

What is MS Access and How Does it Work?

Microsoft Access is a database management system for storing data and retrieving it as per requirement. Software Developers, Data Architects, Power Users and other professionals, use MS Access for developing applications.

MS Access utilizes Microsoft’s Relational Microsoft Jet Database Engine – RMJDBE with an interactive Graphical User Interface in parallel, which is quite appropriate for small applications & businesses. MS Access is also a part of Microsoft’s Office 365 suite.

Why Access Database Files Become Corrupt?

There could be numerous reasons behind why MS Access Database file(s) become corrupt or damaged:

• Write operation interruption
• Defective network hardware
• Opening Access database file(s) in non-native programs

Write operation interruption – it can happen due to sudden or unexpected exit from the application while a write operation is ongoing or force exit of the application. In such a scenario, the Jet database engine marks the database as suspect/corrupt. The sudden shutdown can also lead to the same issue.

Defective network hardware – faulty network peripheral could cause the database file to turn corrupt. The network hardware not being in the normal state would directly affect the Jet database engine, and further Jet database engine will set flags on the file.

Opening Access database file(s) in non-native programs – in cases when someone opens MS Access database file(s) – MDB/ACCDB files, with other programs on their system it can cause the database file(s) to go corrupt.

Measures to Avoid Access Database File Corruption

To prevent Access Database corruptions the vice-versa of the aforementioned-points is the best. Make sure you do not exit or close before the initiated write operation completes or your Windows machine does not surprise you with frequent shut-downs. Regarding the faulty network hardware, a regular check would be fine unless you are ready to lose essential information. Well, it makes no sense in opening MS Access database file(s) with another Windows program as these files are meant to be accessed using the native application – Microsoft Access.

Make sure you always have an updated backup of the MS Access database file for quick data restore when it becomes inaccessible or damaged due to any reason. Also, delete the Microsoft Access lock information files, also known as .ldb files manually which can be the cause behind the database corruption in the future. Some other preventive measures which you must take are-

1. Make sure you do not exit or close before the initiated write operation completes or your Windows machine does not surprise you with frequent shutdowns.
