CREATE FILE encountered operating system error 5(failed to retrieve text for this error. Reason: 15105)

Question

I have a database file .mdf from MS SQL EXPRESS in folder:

C:\\Program Files\\Microsoft SQL Server\\MSSQL10.SQLEXPRESS\\MSSQL\\DATA

Answer 1

I got this error when restoring a database that was backed up on another server. After a long struggle this is what I did

1. Enabled Instant File Initialization,

2. Granted permissions (full control) on the folder to the service account and my own windows account,

3. Restarted the SQL service. Database restored after that.
