Hello,
The one listed as 'failed' actually fails for me as it is sent .
I was experimenting by moving the value near the top of the file.
It continues to fail whether the entry is at the bottom of the file
Or where it appears in the sample that I sent to you.
Could it be a line feeds issue?
I haven't tried running unix2dos/dos2unix against the HDR files.
Does the program mind if the EOL are \13\10 vs. \10 ?
Best Regards,
Peter

With both headers, gdalinfo correctly reports the nodata value... But you didn't send the .hdr files you've generated since the "data ignore value" is not at their end.
