In all of the cases I have seen the corruption was triggered by opening
and closing an excel spreadsheet which results in 8 bytes being written
to the spreadsheet header.  The header becomes corrupted with either the
first 1K or 4K of the file being replaced by NULs instead of the actual
header file.  The last modification timestamp is preserved by Excel.
