I fixed one error!

The Database is Read-Only doing Detach/Attach. So when i try to make it Read-Write, it keeps returning the following error:

Msg 5120, Level 16, State 101, Line 1

Unable to open the physical file "E:\MSSQL\Data\MY_DB.mdf". Operating system error 5: "5(failed to retrieve text for this error. Reason: 15105)".

Msg 5120, Level 16, State 101, Line 1

Unable to open the physical file "E:\MSSQL\Data\MY_DB_log.LDF". Operating system error 5: "5(failed to retrieve text for this error. Reason: 15105)".

Msg 945, Level 14, State 2, Line 1

Database 'MY_DB' cannot be opened due to inaccessible files or insufficient memory or disk space. See the SQL Server errorlog for details.

Msg 5069, Level 16, State 1, Line 1

ALTER DATABASE statement failed.

any clue ?

Thank you
