I put Drive 2 back in it's Easystore enclosure, connected it to my windows PC, ran the WD App and even there the "SMART Status failed" Would I be correct to assume that SMART info has noting to do with the type of file system? And is there a chance that if the SMART isn't working for the disk that you can still read from the disk platter somehow?

So your saying my only option is a data recovery service?

So what's the safest way at this point to rescue the data from Disk1? 1) in the new unraid install (6.8.2) try to add the disk as an unassigned drive and copy to a 2nd disk? 2) boot up an ubuntu VM on my Windows PC (ESXI Workstation), unlock the file system and copy to a 2nd disk? 3) use a recovery program? (recommendations?) 4) just take it to a data recovery guy in my area and get his initial evaluation? (~$200) i'd also like to see if he can sniff out the cause of the problem before I change all my other hardware out. Note that i have my Cache pool drives intact. I spent a significant amount of time organizing my plex metadata and adding images/posters etc. I would like to keep this.

So this means I just run a diagnostics report after changing the controller type and rebooting? I tried all the disks and they would not show in unRAID at all. Only an SSD. I don't have another HDD to test When I found it the PSU was off. It's a really simple enclosure. It's just on or off. There's not much to it. No individual disk control. Not even a power control for the entire enclosure. I'll check the log tomorrow. I definitely feel the disks spin up. They don't stop spinning until disconnected.

A few more things I've tried: - I've tried changing the controller type as you recommended. It was already set to "Automatic." I changed it to a few different things from the list with reboots each time, then back to "Automatic" and a reboot and still could not run a SMART Self test. - I tried connecting the drive with a powered USB to SATA adapter. This one to be exact. It would not show the drive at all in unRAID. It did show a spare SSD that I connected. Maybe this adapter doesn't work on 8TB drives? I did tape the 3.3V pin again. - I removed the PCB that's attached to the HDD to inspect for damage. Did not see any burning or arcing marks. - I disassembled the backplane of the iStar USA hot swap enclosure to check for shorts or damage. I used my multi-meter to check for continuity shorts between the different voltages and grounds. Did not find any issues. - I checked all voltages while the backplane was connected to the power supply. Everything seemed normal except SATA power pin 11 had 1.6 volts. I'm not sure if this is normal or not. I read it has something to do with "Staggered Spin-up" although i'm not sure if that is just normal. Someone on Reddit recommended I use a program on windows called HDDSentinal. It's about $30 which I don't mind. I would really like to understand why this happened. So I can prevent it from happening again. What do you recommend for the next step? I'd like to see if I can save the data that's on Drive 1. Should I try the program Recuva? I've used this before on an SSD with success. (this drive is XFS Encrypted) Then maybe I'll send a disk to a hard drive tech for some forensic work. Spending a few hundred to find out why it happened is less than buying another $500 in drives and it happens all over again. Pretty bummed. This is my first server and first NAS. What a pain this is.

I don't know how to test this but I'd like to try.

I'm not sure about the power spike. The enclosures are powered by a relatively new, quality PSU that's plugged into a relatively new UPS / surge protector. Along with other devices powered by same UPS (server, rasbPi, cameras) and no other devices are damage but the 3 disks. The UPS logs events and shows no issues. I can't find instances written in other forums where a new PSU fries a computer in its own. At this point I can't just replace the drives without knowing what caused this. HBA? PSU? Enclosures / Backplanes? Cables? Software? UPS? If I'm going to buy $500 in new drives I'll need to replace all of this so it doesn't happen again. So we're talking about a $1000+ hit here. Not including the hours to archive and entire Blu-ray collection all over again.

ok, I ordered a SATA to USB powered adapter. Will arrive to me on Sunday. Thanks and have a nice weekend

I connected the drive to it's Easystore board. Plugged in the drive via USB. I can't run the SMART test. Maybe the Easystore enclosure board has an effect? Should i assign i to the array?

Instead of the SATA to USB adapter can't I just put it back in the Easystore enclosure it came with?

I don't have one but I could order one. So it could connect via USB but not directly with SATA? I'd like to try this but it wont mount to the old unraid OS. Should I try a Ubuntu OS? And try to copy it from there? I need just the data from Disk 1. I don't have a backup. I can't believe 3 nearly new drives would all fail at the same time. Is there a service I can contact for help? Or should I contact Western Digital?

ok @Benson when I click on Start next to "SMART short self-test" and "SMART extended self-test" the start button changes to "stop" then immediately back to "start." And nothing happens. Is there something i need to do before i can start the test?

Will the Extended SMART test destroy my data?

Ok I'll run the test when home from work. How can 3 disks go bad at the same time? Is this normal for just having power cut off once? Is there a way to clear the errors? Thanks for your help.
