Microsoft Access database is a useful utility, with which users can maintain databases for continuous management of information. Access database corruption can land you up in trouble. Mostly, the fatal system errors like an invalid page fault, an application exception error, or a STOP error force the Windows-based applications such as Microsoft Access to fail and it just stops responding. Adding to worst, these errors even cause the operating system to stop responding. Some of these errors are as follows:
“The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.”
“Cannot open database ‘filename.mdb’”
“Invalid field data type error 3259”
“Unexpected error 35012”
“Record(s) cannot be read; no read permission on ‘xxxx’ (Error 3049)”
“Error 3022- The changes you requested to the table were not successful because they would create duplicate values in the index, primary key or relationship.”
“Error 2239- The database ‘filename.mdb’ needs to be repaired or isn’t a database file.”
These fatal system errors could be attributed to the following reasons:
Something unpredicted occurred within your system, or there is improper memory addressing; Windows application might read from or write to a memory location which has not been allocated to the same; there is overwriting of data, damaging the original content.
Invalid restrictions have been approved between the applications and the Windows environment. The invalid parameters cause the invalid instructions, resulting in page faults. This is generally caused by the internal code problems of the application.
For troubleshooting, you need to analyze the causes of the errors in MS Access.
An incorrigible bug in the Microsoft Access
A corrupted or damaged Access database
Fragmentation in the database
Inappropriate registry settings
Damage or corruption in file systems
Faulty network devices and connections
Mismatched DLL (Dynamical link Library) files
Damaged file header
LDB file (Lock file) use for database read/writes synchronization
Conflictions with installed third-party drivers
Once these errors cropped in the Access database, data corruption becomes inevitable if timely action is not taken. To make your database accessible again, you need to resolve these issues as early as possible.

These are the few examples of errors one may face while trying to access or fetch any data from the corrupted database.
Possible Manual solutions for these Access database corruption issues are:
If the problem is due to the inveterate bug in access, inappropriate registry entries, or mismatched DLL files, then you must reinstall Microsoft Access.
You can try Regedit tool. For this, click on Start button and type regedit to search. Now run the registry editor and select the Microsoft access key. After selecting the key, click on the File tab and from the menu, select the Export option. After following all these steps, save the file at the destination folder by providing a name to the file.
Use the inbuilt Microsoft Compact & Repair Utility integrated into the application. Launch the MS Access application, click on the Database Tool tab, then follow Database to Compact from> Compact option. Use the Browse option to add the database which you want to compact and click on the Compact option. It will start the compact and repair operation on the database. Click the Save option once the process is completed to save the compacted file and use it further.
You can go for the manual method too. For this, you need to open MS Access application and click on the External Data tab. From the menu of Export group, select more options and click on Access Database. After completing previous steps successfully, save the file at the desired location and click on Ok. The final step is assigning the new name to the element and clicking on Ok.
You can recover all database objects easily with the help of Kernel for Access Database Repair software. First, install and run the software. Then follow the below-mentioned steps.

Because, as we can see the manual method is quite a time-taking and complex process, and there is no surety of a 100% solution. With the help of Kernel for Access Database Repair software, you can successfully recover data from a damaged access database.
