Removing files after reboot

Hello everyone, I’m recently starting Umbrel, I’ve been running my OS for about 3 days.
I have a Raspberry 5, 4gb, SSD 1tb, version umbrelOS 1.2.1

let’s get to my problem,
I’m setting up a Jellyfin server, with qBittorent I’m using an RSS channel through autobrr, everything was working very well, that’s when I had to turn off my Rasp to carry out maintenance on the physical installation, remove it from the bench and place it in the appropriate location.

Can someone help me? I don’t know where I’m getting lost, the HD is the same, if I have an electrical problem will I lose all my files?

I went to turn it off, when I turned the device on, my HD, which had more than 100GB of downloaded files, was simply deleted.
however the file scheme I created “Bittorren






t/downloads/downloads” the folders are there, but the files are not.
