Posted August 23, 2016 Dear All, Hi. I have a server with the following installed: Windows server 2008 R2 SP1 SQL Server 2008 R2 My production database was "mydb" The production database files were stored as below : 1) "mydb.ndf" file was stored at "C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\mydb.ndf" 2) "mydb.mdf" and "mydb.ldf" files were stored at D:\myfolder Due to some reasons the Hard disk crashed and I lost my C:\ drive leaving me with only the ".mdf" and ".ldf" database files. I have re-installed the Windows server 2008 R2 SP1 and SQL Sever 2008 R2. Now when I try to "re-attach" "mydb", by following method : Right click Databases->Attach->Add, select the .mdf file and click OK I get the following error : "Unable to open the physical file C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\mydb.ndf". Operating system error 2: "2(The system cannot find the file specified.)" (Microsoft SQL Server, Error : 5120) My Query : How can I recover/restore the database from just .mdf and .ldf files ? I've tried the following : 1) Creating a "mydb.ndf" file and saving at the same location but SQL server is not able to map it to "mydb.mdf". 2) Creating a new "mydb" and over-writing "mydb.mdf" and "mydb.ldf" to the newly created location. Please advice a solution as this recovery is very crucial for me. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

Posted August 25, 2016 Well, .ndf files are per default secondary data files. Without a backup of it, you will definitly have data loss. The severity depends on your file/file group to table distribution. When you have the Enterprise edition, than you can do a partial restore of the primary file group. Otherwise it's not possible to restore the database without the .ndf files. When you know the exact configuration of your database, tables files and filegroups, then you can create a dummy .ndf and use this file in a restore operation. The easiast solution: restore it from your backup. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted August 26, 2016 Author Thanks for your response, I have restored the database from a backup and I've got the .ndf file. But there are two issues : 1) the new file created after restoring carries a different .ndf file name. 2) How do i link the latest .mdf & .ldf files with it. Is it at all possible. Thanks in advance.

Posted August 26, 2016 Detach you database. Overwrite the mdf and ldf files you've restored from your backup with your files from the D: drive. Reattach the database. There is no guarantee that this will work or if it works, that your database is in a state where you can continue to work with. If that doesn't work then there is an option to try to restore database using SQL Server Recovery Toolbox. It is a powerful tool to do recovery for sql server. They have a demo version. So you can check it works in your situation or not. http://www.oemailrecovery.com/sql_repair.html Link to comment Share on other sites More sharing options...
