What do you need to know about free software?
If you’ve used the Access database, you know that it’s Microsoft’s proprietary Database Management System (DBMS). And just as Microsoft’s other applications, it’s efficient as well as very user-friendly. MS Access has a relational MS Jet Database Engine with development tools running at the back and an easy to grasp user interface at the front. The ease of use it offers makes this DBMS a preferred choice for many corporates. However, database files are often plagued by corruption, which can pose a threat to the extremely vital data present in them. MS Access is no different and often faces corruption. This article is helpful for Microsoft Access database repair and you understand the reasons behind MS Access database corruption and the ways in which it can be resolved.
Special Tips – Don’t forget to check out this MDB repair article if you are using MS Access 2003 or lower versions.
Reasons for Access Database Corruption
When the binary file format of a database encounters an error, database corruption occurs. In such a case, users might face random errors or difficulty in using the database. The Jet Database Engine of Access auto-fixes minor issues that crop up in the database from time to time while reading and writing data normally. Due to this, in most cases, you may never find out that something went wrong! This is both good and bad. Good because your work is not interrupted, bad because corruption can become worse with time if not treated. Hence it is important to understand every aspect of Access database corruption.
Here are the main reasons behind it:
- Frequent edits to data in Memo fields increases the chances of Access database corruption. It mostly results from a problem with a VBA module and does not pose a risk of data loss. However, it does pose a risk of database design damage.
- Interrupted change to data — because of network service loss for example — causes Access to mark the database file as corrupted. The file can be repaired, but some data may be missing after the repair is complete.
- If a Virus infects a file needed by the Access database, as soon as that file is used when the database opens, the infection will spread to the database and corrupt it.
- Hardware failures like lost packets on network cards and bad sectors on hard drives can cause database corruption.
- Improperly designed or installed third-party plug-ins for Access can corrupt the database.
- If multiple users of the same database have different Jet service packs and updates installed, minor differences in the mdb file format and file-locking mechanisms can cause database corruption.
- A few bugs in Access and Jet software are sometimes themselves responsible for corruption.
- Though it happens very rarely, improper shutdown of the system while some activity is being performed on the database can lead to its corruption.
Repairing Access database and recovering data
Generally, when database corruption occurs, the only solution we can think of is sending the database to an Access data recovery company or calling their experts over. However, what we don’t realize is that sometimes, the corruption is minor enough to be handled by us ourselves. Here are some manual techniques to rectify database corruption:
- Restore the database from a backup file – This is why backups are very important!
- Delete the .ldb file that is auto-created by the Jet database engine when the database is opened.
- Use the Jet Compact Utility that has been specifically designed to rectify minor corruptions in Access database.
- Remove all compiled VBA code from the database. This can be done using this command line switch from Microsoft:
C:Program FilesMicrosoft OfficeOfficeMsAccess.exe /decompile C:DatabasePathFileName.mdb
Note: You may need to change the path shown above for MsAccess.exe if you installed it to a different location.
- Use the built-in Access 2010 ‘Compact & Repair‘ feature. Here are the steps to fix Access database corruption using this feature:
- Open MS Access (not the database file) and go to Database Tools -> Compact & Repair Database.
- Locate the corrupted database file and click on Ok.
- The selected database file will be rectified on completion of the process
- Import the corrupt database into a new Access 2010 database file by using the following steps:
- Open MS Access and create a new database file.
- Click on Access to Import Access database under the External Data tab.
- In the next window that pops-up, click on Browse and locate the database file while is to be imported.
- Specify the place and technique to store data in the new database and click on Ok.
- From the next window select all database objects that you want to import and click on Ok.
- If even after all the above techniques, the database corruption persists, the recommended solution would be to buy a premium quality third-party Access database repair software.
