Audacity no disk space error has cut my original wav in half

Your problem:
DVDdoug is correct! On an older project I ran into exactly the same problem you described. My WAV file appeared to have all of the audio data (judging by its size), however when opening the file in either Audacity or any other player/editor it cut out at 32min 21sec. My WAV file had six channels so it ran out quickly.

QuantumForce said

I only have the original .wav which is now half the size and length

so (s)he appears to be distinguishing size and length as different things and/or exported the file, which would cause truncation and an error message if there was still not enough disk space. If you copy in the file on import, you need the disk space to do that as well as the space for the export.

Current Audacity should be able to import WAV files between 2 GB and 4 GB without truncation (but not over that size, obviously). Many applications truncate WAV files between 2 GB and 4 GB.

@GNU-Cody

If the WAV file size is greater than 4GB then the audio data is there, but you’ll need a utility that can bypass the WAV container’s 4GB limit and I don’t know of one off hand that can do this easily.

If QuantumForce’s problem is as per your interpretation (the file is over 4 GB), then I think File > Import > Raw Data… would solve it. You just need to remove the click at the start caused by the file headers.

To export to a lossless format that can accept almost unlimited size, try RF64 (though be aware that only “advanced” players such as Foobar2000 will be able to play it).

From 2.0.6 onwards (when released), Audacity on Windows won’t have the 2 GB limitation when writing FLAC because 2.0.6 uses a much more recent libflac that has solved this problem. The problem will still be there with many other Windows FLAC encoders (unless they update their FLAC version).
