For example, if you encounter the following error message in the SQL Server Errorlog file, SQL Server encountered operating system error 2 when it uses a Windows API call to write to the tempdb primary database file:
Error: 823, Severity: 24, State: 4
I/O error 2(The system cannot find the file specified.) detected during write at offset 0x00000000284000 in file 'D:\Program Files\Microsoft SQL Server\MSSQL\data\tempdb.mdf'
Because SQL Server has already successfully opened the file and did not receive an “Invalid Handle” error, the error is likely being raised in a lower-level kernel software component, such as the file system or a device driver. This problem does not indicate a problem in SQL Server, and it must be investigated as an issue with the file system or a device driver that is associated with the file.
Does that mean this is not a SQL Server error?
Does that mean something wrong with my operating system? or something wrong with my hard disk?
