Corrupt Data Base

[Davet102]

Running Vista and Office 2007.

I deleted a Access Data base file by accident. It is gone.

I restored it from a backup.

Tried to open it and got this message:

"Cannot open c:\users\name\documents\file list.accdb May not be an
application that your database recognizes or is corrupt"

Went throught the help sections and that did not help at all. Could not find
a "Access Database repair" tool.

How do I get this database back??

First, always work on a copy of the database. Working on the original may
make it impossible for a repair service to fix it.

Decompile your database:

Download a copy of JetComp.exe:

Try backing up your forms as text with the undocumented SaveAsText
LoadFromText functions:

Also have a look at the Microsoft KB article:

http://support.microsoft.com/default.aspx?scid=kb;EN-US;209137

Then have a look at Tony Toews' Access Corruption FAQ at:

http://www.granite.ab.ca/access/corruptmdbs.htm

for some suggestions. Unfortunately, some corruption cannot be fixed - you
may need to create a new database, import what can be salvaged, and recreate
the rest.

Although it's a paid service, Peter Miller does an outstanding job of saving
corrupt databases. Try this URL:

It's time to move to SQL Server, you should have done this a decade

In Microsoft's own words....
The following comes from Microsoft article Q300216.

-----------------------------------------------------------------------------------------------------------------------------------------------------------
"Microsoft Jet is a file-sharing database system. A file-sharing
database is one in which all the processing of the file
takes place at the client. When a file-sharing database, such as
Microsoft Jet, is used in a multiuser environment,
multiple client processes are using file read, write, and locking
operations on the same shared file across a network. If,
for any reason, a process cannot be completed, the file can be left in
an incomplete or a corrupted state. Two
examples of when a process may not be completed is when a client is
terminated unexpectedly or when a network
connection to a server is dropped.

Microsoft Jet is not intended to be used with high-stress, high-
concurrency, 24x7 server applications, such as Web,
commerce, transactional, and messaging servers. For these type of
applications, the best solution is to switch to a true
client/server-based database system such as Microsoft Data Engine
(MSDE) or Microsoft SQL Server. When you use
Microsoft Jet in high-stress applications such as Microsoft Internet
Information Server (IIS), customers have reported
database corruption, stability issues such as IIS crashing or locking
up, and also a sudden and persistent failure of the
driver to connect to a valid database that requires re-starting the
IIS service."
