No luck for me only, did 30/30 power only cycle x2, then plugged into usb caddy
and get this when i disconnect it
with it connected I get

Well, the main cause of divorce is marriage.
Same with drives, they die at some point.
Were these 850 EVO drives or PRO? Were there any issues with power failures while the drives were active? What model of Intel NVMe drives will you be using? Don't want to distract you from restoring, just wondering.

Bummer. Sounds like you just got a DOA SSD. Could leave it plugged in for a longer period of time and see, but just sounds like it's toast.
EVO's.
Never, ever, had a power issue on that node or anything of the likes. We've rebooted the node in the past for kernel updates and such without issue.
We're using Intel P3600's and things like that. They aren't as fast as the 3700 series but it's shared hosting, we don't need 400,000 IOP writes. Very high endurance which is nice.

The 850 use 3D NAND, the 840 old school MLC NAND. Less chips, less PCB, cheaper to produce. If the base if one of those 3D nand chips fails, your disk is dead. If you reached the maximum data written for this component, it's likely that all disks will die at the same time, or almost. (On Intel 520 - using real and good MLC - the data is compressed on the fly to write less on the chips and it is supposed to be able to survive a dead chip, at least from what I read, didn't try it myself: all SSDs aren't created equal...)
This is why our raid arrays use different brand/model drives. With that comes other issues though.
Do you run into a lot of stability issues there?
Or just use drives from different batches/with different wear levels - though that's easier said than done.
Not a terrible idea.
I've made design changes to this node which will allow me to likely take deduplicated block based backups which I'll do along side Jet.
As I said, so far only the 850 1TB's have given this issue.

I've seen plenty of discussion on forums of Samsung Enterprise SSD's doing the same thing (the PM series) so I'm not going to rush to blame TLC, especially given my 840s' are happy clams.

last chance of rescue is ddrescue
You’re almost at 15 posts!
If we could see the drives but we can't, they never properly bootup.
If this was just a case of needing dd rescue i would've completed that last night.

And where do you see spam here ? I only said to take backups which part of the line contained spam ?
@Francisco Did you tried to put these disks to another server? About a year ago I had a similar situation with my wife's laptop disk. I put the disk into my laptop but it didn't help. Then I switched the disk to my PC and I was so supriesed- disk appeared.
Earlier in this thread I mentioned that we tried no less than 4 different servers and around 6 different chipsets/HBA's to try to get it going.

As I said in small text, I had no such intention!
@Inded_Hosting It's a running joke here that all new hosts rush and create 15 crappy posts to meet the requirements. (i.e. I have nothing against you.)
But you do know that am only a shared hosting provider and i cant do anything even if i reach that number don't you ?
@doghouch Just take a look at his profile.
Edit: there we go, permanent ban is now secured.
There is a url at my signature put the glasses on and check it...
@Francisco I'm sorry, I didn't notice it. From my side I only wish you good luck. If you will able to run with these disks, please share what You did.
When I order new drives from our vendor, can't really specify different batches.
Much easier to just order lots of different models/brands.
It also makes it easier to identify dodgy disks since the serial number is often obscured by the disk cradle.
It was buyshared not buyvm champ
