When some applications update very large files (1 terabyte or 2 terabytes) in Windows Server 2008 or in Windows Vista, you may receive an error status message from the ntfs.sys driver. The error status message may resemble one of the following error status messages:

0xc0000427 STATUS_FILE_SYSTEM_LIMITATION
0×299 ERROR_FILE_SYSTEM_LIMITATION

For example, when you perform the dbcc checkdb action on a large database file, you may receive the following error message:

The operating system returned error 665 (The requested operation could not be completed due to a file system limitation) to SQL Server during a write at offset [address] in file [file name].
