ST2000DM008 strange problem

[corrado@exformat.com]

good morning, and thank you very much all the forum for the great content. I wanted to prove this weird case that happened accidentally.
4 ST2000DM008 disks mounted in raid 0 on intel controller. Quick format was launched due to an error, which also crashed.
A few seconds after the command, the PC was immediately restarted.
Obviously the structure of the rai has been damaged, the strange thing however is that by connecting the individual disks, to virtually reconstruct the raid 0, they contain very little data, some fragments of the partition, but going into the HEX edit by randomly checking the physical surface all the data are at 0. How is it possible that in about ten seconds in all 4 disks the data has been cut down to zero for 99% of the physical surface? I'm missing something is there a hardware check inside the disk that simulates this? thanks for your cooperation.

the trim is disabled, but I see the whole surface of the disk only that I see it at zero ... since it is hdd, the trim should not create artifacts, it is not an smr disk, at least I think, more remains to be verified?
Thank you
