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.

I would say it might be due to Trim, but Trim can only affect MC on seagates IMO, so the data that wasn't stored in MC should not have been trimmed...
Strange issue...

Then there are not a few data, but looking in the HEX edit the surface, actually after the 200Gb there is nothing left ... Before the disks were full, I hoped there was some sort of wipe. But I don't really know how to check. Thanks for all help and advice

On SSD it be Trim but on HDD Data should be there hopefully. You require Raid reconstruction to get data folder wise, Or see at-least Raw.

Some (all?) SMR HDDs support TRIM.

I think only WD and some very new Seagates (this could be the one).
It can be checked using free HDD tools

I would dump the drive's Identify Device data and check whether it reports its TRIM features. The manual states that word 69 is 0000h, but Seagate's documentation is full of errors and omissions.

If trim affects data outside the MC as well, it would be easy to recover it by clearing trim records from MCMT, i guess...
yeah, as far as this is easy

May be but don't experience yet. Format command applied for few second !

A user in this thread mentions his drive, of the same model, supports TRIM.
