You can use an editor which allows you to change binary files, such as emacs,
to correct the 'number of records' in the file. This is a bigendian 4 byte
integer which begins at the 4th byte in the file.

This is what the first eight bytes would look like in emacs if you had zero
records:
CDF^A^@^@^@^@
and this is what it would like if you had 6 records (^F is ascii 6)
CDF^A^@^@^@^F

See Appendix B of the netcdf user's guide for more info.
