Answer 1

1) If possible add more hard drive space either by removing of unnecessary files from hard drive or add new hard drive with larger size.

2) Check if the database is set to Autogrow on.

3) Check if the account which is trying to access the database has enough permission to perform operation.

4) Make sure that .mdf and .ldf file are not marked as read only on operating system file system level.

To back up your databases

Launch TFSBackup.exe. The TFSBackup.exe tool is in the Tools folder where you installed Team Foundation Server. The default location is C:\\Program Files\\Microsoft Team Foundation Server 12.0\\Tools. In Source SQL Server Instance, enter the name of the SQL Server instance that hosts the TFS databases you want to back up and choose Connect. In Select databases to backup, choose the databases to back up. Need help? List of TFS 2010 databases on MSDN; List of TFS 2012 databases on MSDN. In Backup Databases to, enter the name of a network share that is configured with read/write access for Everyone, or accept the default location in the file system of the SQL Server you connected to in step 2. Note Note If you want to overwrite backups stored in this network location, you can choose Overwrite existing database backups at this location. Choose Backup Now. The Backup tool reports progress on each database being backed up. Choose Close. Restore your data

To restore your TFS data

Launch TFSRestore.exe. The TFSRestore.exe tool is in the Tools folder where you installed Team Foundation Server. The default location is C:\\Program Files\\Microsoft Team Foundation Server 12.0\\Tools. In Target SQL Server Instance, enter the SQL Server instance you will use as the data tier and choose Connect. Choose Add Share and enter the UNC path to the network share that is configured with read/write access to Everyone where you stored the backups of your TFS data. For example, \\servername\\sharename. If the backup files are located on the file system of the server that is running TFSRestore.exe, you can use the drop down box to select a local drive. Note Note The service account for the instance of SQL Server you identified at the start of this procedure must have read access to this share. In the left hand navigation pane, choose the network share or local disk you identified in the previous step. The TFS Restore Tool displays the database backups stored on the file share. Select the check boxes for the databases you want to restore to the SQL Server you identified at the start of this procedure. Important note Important For SharePoint, you must only restore the WSS_Content database. Do not restore the WSS_AdminContent or WSS_Config databases. You want the new SharePoint Foundation versions of these databases, not the ones from the previous version of SharePoint or from a SharePoint installation running on any other server. Choose Overwrite the existing database(s) and then choose Restore. The Database Restore Tool restores your data and displays progress reports. Choose Close.

Answer 3

Probably your database is corrupt either due to an unexpected server restart or filesystem corruption. You can use CheckDB to check for issues & remove the suspect status. However, the best bet is to restore it from a working backup.

Some reasons for when this happens are

1. Database is corupted database files are being "opened" or held by some process (operating system, other program(s)...)
2. Not enough disk space for SQL Server
3. Insufficient memory (RAM) for SQL Server
4. Unexpected SQL Server shutdown caused by power failure
