lost everything on my 2nd HDD

As I was installing steamos (Linux) onto my computer I figured I would pull out my second HDD just incase something went wrong. Well low and behold when I pulled it out, steamos stopped installing so it seems it was installing on my second HDD. It was only installing for a very brief amount of time though. And now my second HDD (4 TB) is partitioned into 4 drives E: G: H: and I:. Disk E: says it is 486MB and the others don't have a number/amount at all beside them. So I tried recuva and it says

Stage 1 of 3: Scanning drive for deleted files

Current progress: 0%, 0 file(s)found

Estimated time left: 2 days

and it was stuck at 0% for quite some time so I decided to cancel. When I cancelled it, it showed a whole list of files, many of which seemed to be fine. But the problem is for some reason the individual files (not the total files combined) are really large. I'm talking too large to put on a 5TB external HDD

Any help would be muchly appreciated

Thanks
