Cause: The file header block is internally inconsistent. The
beginning of the block has a header with a checksum and
other data for insuring the consistancy of the block. It is
possible that the last disk write did not operate correctly.
The most likely problem is that this is not a datafile for
any database.

Action: Have operating system make correct file available to
database. If the trace file dump indicates that only the
checksum is wrong, restore from a backup and do media recovery.
