Error,while restoring the database in MS SQLserver 2008R2

Error: “The file “C:\Program Files\Microsoft SQL Server\MSSQL.2\MSSQL\DATA\mastlog.ldf” is compressed but does not reside in a read-only database or file group. The file must be decompressed.”

solution1:Opened my mdf file properties dialog box, and in the advance tab the problem was revealed: the “compress content” checkbox was checked.

After unchecking and saving changes, SQL Server accepted the attach with no problem whatsoever.

solution2:Check the drive where data base is going to restore.Right click the Drive(C: Drive)--> Property-->General-->Compress this drive to save the disk space(it should be unchecked )
