A Jet Database Engine serves as the underlying component of a database and all the information is stored on it in the networked scenario. Any wrong thing happened to it, can lead to the corruption of database and in most of the cases where data corrupted is of much importance, needs to be repaired. When some of the corruption happens in the database of Microsoft Jet database engine 3.x, following are the most common error messages returned:

“The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.”

This error message is displayed when the long value column has bad data stored
in it. The page in which the row is stored differs from the one in which the long value is stored. But if it is stored in the table schema, then a pointer is used in the data row to read the data in it and the problem encounters when the row pointer is unable to read properly the data in the long value page.

Another error message which occurs when the Jet Database Engine improperly shuts down while the process of writing down to the disk was going on displays:

“Unrecognized database format ‘databasename.mdb’.”

Also due to misplacement of an index on the MSysObjects table, an error message is encountered that announces:

“’databasename.mdb’ isn’t an index in this table. Look in the Indexes collection of the TableDef object to determine the valid index names.”

This problem is particularly caused when the repair procedure is aborted.
