is there a way to extract a large jpeg file from a corrupt raw file? I can view the file
One way is to use ExifTool:

The CLI code would be similar to:
exiftool -b -previewimage -w .jpg '/Mac OS/Path/to/File/myrawfile.nef'
exiftool -b -previewimage -w .jpg "C:\Windows\Path\to\File\myrawfile.cr2"
Is the corrupt raw file a NEF?
Have you tried other raw conversion software?
Can you convert to DNG?
