Okay. So long story short, I was working in Adobe Premiere yesterday and saved a video to my external hard drive and it ended up being over 1GB. I began to drag it to another folder and Finder crashes. I leave it for about 10 minutes and nothing. So I force closed Finder.
Only then, a folder of 15,000 photos (the one I tried dragging the video to) got deleted. At the time I noticed that the Google Photos Uploader app (which is connected to the folder) had it's contents deleted, so the app didn't work. And then I discovered the same thing happened to Adobe Lightroom. So. Everything's gone.
I tried out DiskDrill and nothing really turned up. Currently waiting on its deep search recovery -- so far nothing. I also tried out TestDisk. It seems more promising to produce results...but when I navigated to the right spot to "undelete" files it said there was nothing to undelete.
So. Is there anything I haven't tried or am I as hopeless* as mashed potatoes?
*Note: I actually have everything backed up to Google Photos, so it's not the worst thing in the world. But it took a week to upload and could take just as long to download...
