Why does a database go into suspect mode?

Why does a database go into suspect mode?

The main reason why the database goes into suspect mode is because the primary file group has been damaged and the database cannot be recovered during the startup of the SQL Server. Also, the database can get in the SUSPECT state for multiple other reasons, which can include: a damaged LOG file or a damaged MDF file.
