I shut down to install more memory and rebooted to discover this. Unraid can’t find parity and a data disk. I’ve tried multiple combinations of power and data cables with no luck.

 

is my data toast? If I got one of the drives recovered, can I convince unraid to use it as a parity or data disk?

 

As usual, I didn’t have an adequate backup implemented yet, so there’s no buying a new HDD and pulling it down from there. If the data recovery route will work, it’ll be an expensive lesson that could have been avoided with backblaze. Live and learn….

Do the drives show up in BIOS?

 

Attach diagnostics to your NEXT post in this thread.

BIOS does not see the drives. I've tried swapping cables all around. I took the memory back out and only had the sticks that were in there previously.

 

I have a spare CPU and MB, maybe I can hook them up to that and see what happens...

Those drives may be the type that won't spin up if they have 3.3V applied on the SATA power cable, did you by any chance change how the power to the drives was routed? 4pin to SATA power adapters will allow the drives to work, regular SATA power may not unless the pins are masked off.

 

This may NOT be the issue, just a possibility since they don't show in BIOS.

I didn't even think of that! I did have them running off splitters before, but tried to "tidy" up the cables and reran all SATA plugs. I'll reinstall splitters and report back!

YOU DA MAN! Looks like I'm going to have to use splitters after all. Thanks for the help!

 

Could it be because these drives were shucked? I have a retail Red Plus that runs just fine off the PSU's SATA cables.

 

Tossed a little somethin' your way. Have a coldie on me.

 

 

 

I'm setting up Backblaze B2 right now. This was too close for comfort, even if it was user error.

Kinda, not all shucked drives act this way, but a good percent of the 8TB WD that were so popular a couple years ago are.
