Fix Corrupted Access Database

[Concordia Zentner]

WE had this problem on one machine and not another...the solution is to look in control panel at the VERSION of the Access Database Engine 2007 component. If it is version 12.0.45, you need to run the service pack 3 -us/download/confirmation.aspx?id=27835

After much struggle with this same issue I was able to solve the problem by installing the 32 bit version of the 2010 Access Database Engine. For some reason the 64bit version generates this error...

Try to create a new database and import every table, query etc into this new database. With this import Access recreates all the objects from scratch. If there is some sort of corruption in an object, it should be solved.

Sometimes it might depend on whether you are using code to access the database or not. If you are using "DriverJet" in your code instead of "DriverACE" (or an older version of the DAO library) such a problem is highly probable to happen. You just need to replace "DriverJet" with "DriverACE" and test.

There are several approaches to compacting and repairing a database. A common practice is to automatically compact and repair a database when it closes. In addition, you can manually run the Compact and Repair Database command, when you have a database open, and on a database that is not open.

Make a backup of the database During the repair process, Access may truncate some data from tables that are damaged. It is sometimes possible to recover this data from a backup. In addition to your regular backup strategy, you should make a backup immediately before you use the Compact and Repair Database command. For more information, see Protect your data with backup and restore processes.

Get exclusive access to the database A compact and repair operation requires exclusive access to the database file, because the operation may disrupt other users. You should notify other users when you plan to run a compact and repair operation, so that they can avoid using the database during that time. For more information, see Open an existing Access database.

Tell users how long they must avoid using the database. If you run compact and repair operations on a regular basis, keep a record of how long it takes. You can then make more precise estimates that give other users guidance on how long they should avoid using the database.

Get sufficient file permission to the database If you do not have sufficient permissions and you need to compact and repair a database, contact your system administrator for assistance. For more information, see Changes to file sharing over a network in Windows.

You can select the Compact on Close database option if you want to automatically compact and repair a database when it closes. Setting this option affects only the database that is currently open. Set this option separately for each database that you want to automatically compact and repair. In multiuser databases, you might not want to set this option, because it can momentarily disrupt database availability.

If Access completely repairs a corrupted file, it displays a message stating that the repair was successful and that you should check the database contents to be sure that everything is as it should be.

If Access is only partially successful, it keeps track of database objects that it could not repair in a system table named MSysCompactErrors. Access opens the MSysCompactErrors table in datasheet view. If you have a previous backup before the database was corrupted, you can use the MSysCompactErrors table to decide which objects to import into your repaired database. To reveal system tables, right click the Navigation title bar, and then in the Navigation Options dialog box, select Show System Objects.

This overview explains how using the Compact and Repair Database command can help prevent and correct the following problems that sometimes affect a database: files growing larger with use and files becoming corrupted.

As your database file fills up with the remains of temporary and deleted objects, its performance can degrade. Objects may open more slowly, queries may take longer than normal to run, and typical operations generally seem to take longer.

In particular circumstances, a database file can become corrupted. If a database file is shared over a network and multiple users work directly with the file simultaneously, that file has a small risk of becoming corrupted. The risk of corruption is somewhat greater if users frequently edit data in Long Text fields, and the risk grows over time. You can mitigate this risk by using the Compact and Repair Database command.

Often, this type of corruption results from a problem with a Visual Basic for Applications (VBA) module and does not pose a risk of data loss. However, this type of corruption does pose a risk of database design damage, such as lost VBA code or unusable forms.

Summary: Is your Access database corrupt? Need to know how to repair a corrupt Access database? Read this post to explore the methods to repair a corrupt Access database. Also, check out step-wise instructions to recover data from the corrupted db. If nothing works, use Stellar Repair for Access software to repair your database and recover its objects without downtime.

Corruption in MS Access database usually occurs when errors are found in the underlying binary file format of the database. When that happens, you may face random errors or difficulty in accessing Access database files (.MDB/.ACCDB).

Stellar Repair for Access is powerful DIY software you can use to repair and recover .MDB/.ACCDB file in a few simple steps. This Access database repair tool previews all the recoverable database objects like tables, deleted records, queries, forms, reports, etc.

An .LDB file gets created when an Access db is opened or accessed for shared use (i.e., in a multi-user environment). The file has the same name as that of the Access database but is saved with an .ldb extension. The file helps in keeping track of all active users accessing the database.

Using the Jet Database Engine of Access helps auto-fix minor issues that crop up in the database from time to time while reading and writing data. Due to this, in most cases, you may never even find out that something went wrong.

There can be umpteen reasons that can turn an Access database corrupt, including increasing database size, hardware or software failure, etc. You can manually compact and repair the database to resolve the issue.

However, the manual troubleshooting steps do not guarantee to recover the complete Access database. Stellar Repair for Access can also help you repair severely corrupt Access databases and recover all the database objects.

We started getting issues with queries not being to run, however that seemed to be related to the November Update from Microsoft. All computers are running Office 2013 Pro Plus and have been patched for that issue.

If you have issues with Access Database and get corrupted then you can go with Aryson Access Database Recovery software - it allows to repair the corrupted database file and create a new database which can be easily open with MS Access.

So, in discussions here and on other sites, and with others who have this problem, there does not seem to be a one size fits all solution. However, everyone, so is in agreement this problem is fairly clear.

I WOULD LIKE THE CONTRACT PROGRAMMER WORLD TO REALIZE THERE IS A LARGE OPPORTUNITY FOR A SOLUTION TO A HUGE PROBLEM. BY POSTING THIS HERE AND ON SEVERAL OTHER BLOGS THAT CONCERN THIS ISSUE, I HOPE TO INSPIRE EXPERT CONTRACTORS TO BRING AN EXPERT SOLUTION TO THIS MARKET. PERHAPS, IF IT IS GOOD ENJOUGH, MAYBE MICROSOFT WILL PURCHASE IT AND INCLUDE IT IN THEIR EVENTUAL SOLUTION.

I am using MS Access 365, my DB instance is getting corrupted whenever I put it on shared drive. Is there some sort of accessibility/privilege change i need to do for it to work. I want to allow multiple users to access and make changes to the DB, it has a lot of forms.

Corruption in shared Access databases has been known to be caused by large numbers of users modifying the database concurrently. If possible, limit the numbers of users modifying the data simultaneously.

Another cause of corruption in multi-user Access databases are users not properly closing the database when finished. Generally, this is hard for a user to do on purpose. However, things like a computer suddenly powering off or restarting, losing its network connection, etc, can leave the database in a bad state.

As mentioned Access is capable of multi-user databases, but that was not its true design. Depending on the usage, you might want to move to a more capable database. Microsoft SQL Server is a true multi-user, robust database. Microsoft offers a free version called SQL Server Express. The free version is very capable. Additionally, you can import your Access database directly into it. There are plenty of other free and paid databases out there, but for ease of migration, SQL Server Express is probably the best choice.

I'm not sure why you have "reports are corrupted" in the subject if you can't even open the complete database. However, the most common cause of this error message in the last 3.5 years is the MONSTER bug for which you can find the workaround here.

I forced a system restart when my storage was showing "Zero bytes available" in Finder, and the system was nearly complete frozen state; as I was opening many heavy load apps and files. The computer never shutdown since almost a week (only sleeps) which during this long working session some new passwords were added to the Keychain Access.

Anyways, after some research, I managed to restore the Launchpad to its state using the corrupted database file located in Library/Application Support/Dock, but I could not resolve the Keychain Access problem.

I have a corrupted Access database at the 2GB file size limit that throws the following error when I try to open. Holding the key down throws the same error, as does linking it from another database. I need to recover the VBA code. Any ideas?
