Please answer the question. All three numbers from Help > About Audacity.
Just to be clear, is this HDD an external USB hard drive, or something else?
Then please search for “saporepo episode 4.AUP”.
You should find and use the AUP file if at all possible.
“Refuses to budge” tells us nothing useful about what you are trying to do.
The steps to follow in the case that you have a recording and no AUP file are at Missing features - Audacity Support . In other words, you must sort the AU files into timestamp order, rename them into a consecutive sequence then use the 1.2 Recovery Tool.
This is easier done on Windows, but on Mac you can use Automator or you may be able to use the “Linux command-line alternatives for time stamp sorting” in the Mac terminal (see the “automatic recovery tools” link above). The 1.2 Recovery Tool you need for Intel Macs is gaclrecords.org.uk .
I have - with Show Hidden Files enabled. It simply doesn’t exist. Have checked every temp folder, have scoured the external HDD, even checked the recycle bin. Nothing.
I followed those steps with Automator and got the following error with the Recovery Tool (which claims it is 1.1, not 1.2):
The given path “/Volumes/PHOTOS/saporepo4recovery” does not contain any audio files that could be recovered.
Now it’s 2:30AM, my vision is blurring, and despite clearly being able to hear 6-second fragments of our recording I’ve proven incapable of piecing them back together. So I’ve zipped up the contents of the data folder and uploaded it here: saporepo episode 4_data
If any kind soul out there with more experience than me would like to give it a shot, they’re more than welcome. There should be 3 audio recordings in total that combined are about 37 minutes. Stereo, 44100Hz, 32-bit float.
