하지만 실제로는 해당 폴더에 권한을 주어도 마찬가지 상황만 연출됩니다. 더욱 황당하게도 이벤트 로그에는 다음과 같은 항목도 보입니다.

도대체 저 경로가 어떻게 나올 수 있는 걸까요? 다행히 검색해 보면 이런 글이 나오는데요.
SQL Server express service is not starting [closed]
; http://serverfault.com/questions/447808/sql-server-express-service-is-not-starting
위의 글에 따라 다음과 같이 실행을 하니 서비스는 일단 시작이 되었습니다.
NET START MSSQL$SQLEXPRESS /f /T3608
(또는, NET START MSSQLSERVER /f /T3608)
오호~~~ 이렇게 시작하면 DB를 로딩하지 않고 순수하게 SQL 프로세스만 시작시키나 봅니다. 재미있는 것을 알았군요. ^^
그리곤, 각각의 DB 파일 경로를 "alter database" 명령을 통해 원래의 파일 경로로 새롭게 잡아주었습니다.
C:\Windows\system32>NET START MSSQL$SQLEXPRESS /f /T3608
The SQL Server (SQLEXPRESS) service is starting.
The SQL Server (SQLEXPRESS) service was started successfully.

C:\Windows\system32>NET STOP MSSQL$SQLEXPRESS
The SQL Server (SQLEXPRESS) service is stopping.
The SQL Server (SQLEXPRESS) service was stopped successfully.
이렇게 직접 해당 파일들에 대한 경로 설정을 한 이후로는 서비스가 정상적으로 시작되었습니다.
위와 같이 해주었는데도 서비스 관리자에서 SQL Express 서비스 시작을 할 때 다음과 같은 오류가 발생할 수 있습니다.
Windows could not start the SQL Server (SQLEXPRESS) on Local Computer.
Error 1067: The process terminated unexpectedly.
그런 경우에는 실제로 권한이 없어서 그럴 수 있습니다. 만약 SQL Server Express 서비스의 계정이 "NETWORK SERVICE"로 되어 있다면 다음의 파일들에 대해 "Full Control" 권한을 "NETWORK SERVICE" 계정에 부여해야 합니다. (테스트 해보니, Write 또는 Modify 권한만으로는 부족하고 반드시 "Full Control" 권한이 있어야 합니다.)
C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\MSDBData.mdf
C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\MSDBLog.ldf
C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\temp.mdf
C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\temp.ldf
C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\model.mdf
C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\modellog.ldf
