I tried to find help on the forum and the IRC #devuan channel, but seems
useless…

There are 4 drives, two different brands, 3 different technologies (SSD,
Hard Drive, and nvme), and data loss occurred on the HDD and the nvme…
So different technologies, "different controllers", different brands but
they all have in common EXT4. The data vanished in few seconds…

I tried photorec without success. There are not recoverable.

information if needed)
