I have searched the forums and read the docs linked in relevant posts. None seem to apply well, and I'm still having trouble.

 

Added a new drive to my system, pre-clear completed successfully. Drive shows Unmountable. Tried to format, got this error:

Caution: invalid backup GPT header, but valid main header; regen
backup header from main header.

Caution! After loading partitions, the CRC doesn't check out!
Warning! Main and backup partition tables differ! Use the 'c' an
on the recovery & transformation menu to examine the two tables.

 

It's a new, empty disk so I tried gdisk to remove all partitions and add a fresh one. This was completed successfully, but I still cannot format the drive. Diagnostics attached.

removing diagnostics file

Nothing obvious, please post output of

fdisk -l /dev/sdX

 

Thanks for the response; output attached.

type

wipefs -a /dev/sdf1

then

wipefs -a /dev/sdf

and repost fdisk output

Now try formatting again with Unraid and post new fdisk output if it fails.

Well, not much progress.

Very strange, don't remember seing anything similar, run wipefs again but reboot first before formatting in case there's some GPT info still in memory that's causing issues, though when a reboot is necessary there's usually a warning.

Rebooted, here's the output before I start the array. Will post follow-up about how it goes from here.

 

Edit - nope, no love here

Any ideas what could be causing this? It's a new MB, and Memtest ran for hours with no errors so I'm hoping it's not a hardware or memory compatibility issue.

Not really, do you have a different disk you could test with? Also does that disk format and mount with the UD plugin?

Formatting says it has completed with UD, but fdisk gives the same output. And UD never updates to allow mount, just keeps showing "format" button.

Then I would try with a different disk if available, you can just try with UD, no need to add it to the array.

Here's a different drive, this one 4gb. Attempted to format in UD, and here's the output from fdisk

So clearly not a disk problem but no idea what's going on.

OK, thank you for your help and prompt responses. If I wanted to run a deep hardware diagnostic do you have any suggestions?

I would try with a different controller if available.

I put in an old MB and it works fine. Sending this new x570 board out on RMA - I have a fear it may be a quirky memory incompatibility issue that I'll never be able to pin down.
