Recovering from corruption
This article may help if your database is already corrupt
Before doing anything else, make a copy of the corrupted mdb file while Access is NOT running, and without overwriting any earlier backups. This lets you try different approaches and sequences if necessary.
Next, try the built-in repair utility. This very simple solution may work with corrupted indexes, and might even get rid of a corrupted object:
- In Access 2010, click Compact and Repair Database on the Database Tools ribbon.
- In Access 2007, click the Office button (top left), then Manage.
- In Access 95 - 2003, choose Database Utilities from the Tools menu.
If this does not work, follow the steps for the symptoms of your corruption below.
