Access database stores most of its data in a particular MDB file. In some circumstances this database file can get corrupted. Even when the database file is being shared over a network and is being accessed by many users, the risk of the file becoming corrupted is not too large. The real danger of the database file becoming corrupted arises when the users start to frequently edit the data in the Memo fields. This risk continues to grow over time and one of the simplest ways in which you can reduce the risk of corruption is by using the Compact and Repair Database command on a regular basis for your Access database. If you still run into trouble and you suspect that your MDB file is damaged, you may have to carry out an mdb recovery.

Very often, corruption in the MDB file caused by constant editing in the Memo field arises due to a problem in the VBA module. It is rare for this kind of corruption to result in any loss of data. More often than not, there is some damage to the database objects such as forms becoming unusable or VBA code getting lost. As mentioned earlier, the Compact and Repair utility should be able to fix most of these problems.

Let us now understand the circumstances under which a user action results in database file corruption. Typically, it is limited to a single change in data associated with the last action of any user. For example, when the user is in the middle of making the change and the change is interrupted, say because of a sudden network service loss, then the MDB file is marked as corrupted. It is still possible to carry out an mdb recovery but it may happen that the process is not able to restore all the data. In such cases, you may have to resort to using sophisticated repair tools such as Advanced Access Repair from DataNumen. With just a click of a button, you can identify all the MDB files that you suspect of corruption and start the recovery process. Advanced Access Repair can recover all the tables and records from corrupt MDB files in the same structure as the original MDB file.

When you try to open a database file that is corrupt, Access will immediately indicate to you that you should try repairing the file before opening it. Else if you suspect that a particular Access file is corrupt, you can run the utility manually to carry out an mdb recovery. If Access is successful in repairing the file, you will get a message indicating so. On the other hand, if the Compact and Repair utility is only partially successful, it will indicate what database objects it was unable to recover. You could then try recovering these database objects from a backup copy or use Advanced Access Repair to restore all the data from the damaged MDB file. Finally, the best option would be to split the database and limit the loss of crucial data by keeping the data in a back-end file that users cannot access directly.
