INTRODUCTION
The Data directory in Microsoft Visual SourceSafe and in Microsoft SourceSafe includes a database that contains all the files and projects. Although every precaution has been taken to guarantee the integrity of all SourceSafe files, there are certain events that can cause the data in this database to become corrupted.
Errors that relate to the Data directory, to file names such as aacpaaaa, or to missing files such as abaaaaaa.b can occur.
Many factors can cause a SourceSafe database to become corrupted. These factors include the following:
- Power loss
- System hangs (stops responding)
- User terminates a long process
- Bad network connections
- Running out of disk space
- Network problems
- Operating system problems
MORE INFORMATION
Data can become corrupted if you use the FIX* tools with a Visual SourceSafe 4.x or 5.x database.
To analyze and to resolve the database problems that SourceSafe is experiencing, follow these steps:
- Use the Analyze program (Analyze.exe) to search for database corruption or database errors. To run the Analyze program, use the following command:
analyze
sourcesafe data directoryTo run the Analyze program in unattended mode, use the -I- option. For more information about this option, visit the following Microsoft Developer Network (MSDN) Web site:
The Analyze program goes through the database and reports possible problems. If database errors or corrupted database files are discovered, continue through the following steps.
The Analyze program is primarily used to scan a SourceSafe database for integrity and for errors. We recommend that administrators run the Analyze program every one to three months to verify that there are no problems in the SourceSafe database.
- If there are permissions problems, "unable to checkout files" errors, "losing checkout status" errors, or any other errors that refer to the Status.dat file or to the Rights.dat file, run the Ddconv.exe program or the Ddconvw.exe program. These programs update a SourceSafe database from an older format to the current format. By default, these programs are installed in the \Admin subdirectory.
These programs are primarily used by installation scripts. The installation scripts use these programs to verify that the format of an installed SourceSafe database is correct after an update has occurred. The Ddconv.exe program is also used to create a new SourceSafe database. (For more information, see the Mkss utility.) During installation, if SourceSafe cannot find all the installed databases, the administrator may have to run this utility manually. The administrator can also use the Ddconv.exe tool together with the -s option to rebuild files in the database. - If the Analyze program returns errors that refer to "FREE CHAIN," and if you are using a 3.
xversion of Microsoft SourceSafe, run the Fixfree program (Fixfree.exe). The Fixfree program fixes many database errors that the Analyze program reports. For example, the Fixfree program fixes the following database errors:- Invalid extended header structure
- Error in extended header
- Error processing checkout free chain
- Checkout free chain contains a loop
- Checkout chain contains a loop
- If the Analyze program returns errors that refer to "PROJECT FILE," and if you are using a 3.
xversion of Microsoft SourceSafe, run the Fixproj program (Fixproj.exe). You can use the Fixproj program to fix many project errors. For example, the Fixproj program fixes the following project errors:Message 1
Message 2
Message 2

- If the Analyze program returns errors that refer to "PARENT CHAIN," and if you are using a 3.
xversion of Microsoft SourceSafe, run the Fixprnt program (Fixprnt.exe). The Fixprnt program fixes many database errors that the Analyze program reports. For example, the Fixprnt program fixes the following database errors:Message 1
Message 2
The Fixprnt program removes references to projects that no longer exist. For more information, click the following article number to view the article in the Microsoft Knowledge Base:

- If the Analyze program returns errors that refer to "Cannot find file
filename.b" or "Cannot find filefilename.a," the best workaround is to save a copy of the correct current file. Recover both files (filenameandfilename.a orfilename.b) as they existed on the backup. Then, update the files in SourceSafe to the current versions.
If thefilename.a file or thefilename.b file refers to a project, use the Fixproj program to rebuild the project file. - If the Analyze program returns errors that refer to any other type of problem, contact Microsoft Product Support Services for help.
