Question { Apple, 6655 }

Can I recover a damaged SQL Server 2008 database with the undamaged .mdb and .ldf files?

Answer

Their original SQL Server was 2008, with SP unknown, but installed on D: and C: drives.  The power spike corrupted their O/S on the C: drive and someone reinstalled both the O/S and the SQL Server, which is now SQL 2008, SP4.  They have intact files for all system databases, both .mdb and .ldf.  Is there some way they can reconnect with the user databases using the intact copies of the previous system databases?
I have heard that if the SQL Server is stopped, previous Master and Msdb .mdb and .ldf files moved into place and the server restarted, that any previous user database .mdb and .ldf files can be accessed by the SQL server.
Is this the case, or are there details missing?
