Repair Corrupt Access Database File

    Question

  • I am using MS Access 2010 and one of my databases on our shared network does not open for any user. Shows "Unrecognized Database Format." error message.

    I can't even get it to the point of opening. Is there a solution for this?

    Is there any commercial tool to recover data from a corrupted database?

  • To repair a corrupt .mdb database of MS Access, one can try Compact and Repair feature of MS Access. It repairs corrupt database and makes it accessible for database users. Other than this one can also use import feature of MS Access that helps database users import their corrupt database to a new database file.

    If both these solutions fail to fix this corruption,

    Then one must check some third-party access database repair or recovery software. I would like to suggest MDB Repair Kit software here to repair corrupt .mdb and .accdb files. One can check its free demo version before buying its full version. Download the software from this page: http://www.mdb.repair/

    Hope this would be helpful.

  • Based on your description, your Access database is corrupt.

    The Access database file format is very complex. It starts with a file header containing the meta information of the whole file, followed by several parts containing the actual data. You can find more detailed information about the Access database file format by searching on Google with the keyword “Access database file format”. If the file header containing the meta information is corrupt, or any follow-up parts are damaged or corrupted, then you will not be able to open the file correctly with Access. In such a case, the first step is to try to use the built-in repair or recovery function in the Access, to see if it can repair or recover the corrupt file. If not, then you need to resort to a third-party Access recovery software to scan the corrupted file and repair Access database for you. It is also possible to find a data recovery expert or company to do the task, but in most of the cases, they will also use a third-party tool to do the recovery for you.

    The main difference between using the software by yourself and by a third-party service company is:

    (1)          The company is familiar with the data recovery industry so he knows which software is the best one. While you need to search and compare the software online by yourself, which is time-consuming.

    (2)          The company purchases the software for multiple usages, while you purchase the software for one-time usage only. So normally the service fee may be cheaper than the license fee for the software.

    (3)          DIY will keep your data confidential while do the recovery via a company may cause data breach.

    If you want to perform a DIY recovery, then you can first try the build-in "Compact and Repair" command in Access to repair your corrupt database, you can get more detailed info at:

    http://databases.about.com/od/tutorials/fl/How-To-Compact-and-Repair-an-Access-2013-Database.htm

    If the above method does not work, then you can try third-party Access data recovery tools, such as DataNumen Access Repair at:

    https://www.datanumen.com/access-repair/

    I have used the tool in the past and it helps recovering some valuable data for me. The tool has a free demo so that you can try before you buy.

    Good luck!

  • Try to open inaccessible MDB database file into a new database file or try another solution, i.e. implementing "Compact and Repair" function.

    If you are able to recover data then its good otherwise you need to use Access Recovery software. Many are available in the market but I would suggest you to try SysInfoTools MS Access Database Recovery software. Trial version is available for testing purpose.

  • To restore a database, you must already have a backup copy of your database.

    A backup is commonly referred to as a "known good copy" of a database file — a copy in which you are confident of its data integrity and design. You should use the Back Up Database command in Microsoft Office Access to make backups, but you can use any known good copy to restore a database. For example, you can restore a database from a copy that is stored on a USB external backup device.

    You can restore an entire database, or you can selectively restore objects in a database.

    If you do not have a backup copy, you risk data loss and unwanted changes to or corruption of your database design. For this reason, you should make backups on a regular basis.
