phren0logy Posted May 19, 2022 Share Posted May 19, 2022 (edited) 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.

JorgeB Posted May 19, 2022 Share Posted May 19, 2022 Nothing obvious, please post output of fdisk -l /dev/sdX Quote Link to comment
phren0logy Posted May 19, 2022 Author Share Posted May 19, 2022 Thanks for the response; output attached. Quote Link to comment
JorgeB Posted May 19, 2022 Share Posted May 19, 2022 type wipefs -a /dev/sdf1 then wipefs -a /dev/sdf and repost fdisk output Quote Link to comment
JorgeB Posted May 19, 2022 Share Posted May 19, 2022 Now try formatting again with Unraid and post new fdisk output if it fails. Quote Link to comment
phren0logy Posted May 19, 2022 Author Share Posted May 19, 2022 (edited) Well, not much progress. Edited May 19, 2022 by phren0logy Quote Link to comment
JorgeB Posted May 19, 2022 Share Posted May 19, 2022 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.

phren0logy Posted May 19, 2022 Author Share Posted May 19, 2022 (edited) 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 Edited May 19, 2022 by phren0logy updated Quote Link to comment
phren0logy Posted May 19, 2022 Author Share Posted May 19, 2022 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. Quote Link to comment

phren0logy Posted May 19, 2022 Author Share Posted May 19, 2022 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. Quote Link to comment
JorgeB Posted May 19, 2022 Share Posted May 19, 2022 Then I would try with a different disk if available, you can just try with UD, no need to add it to the array. Quote Link to comment
phren0logy Posted May 19, 2022 Author Share Posted May 19, 2022 Here's a different drive, this one 4gb. Attempted to format in UD, and here's the output from fdisk Quote Link to comment
JorgeB Posted May 19, 2022 Share Posted May 19, 2022 So clearly not a disk problem but no idea what's going on. Quote Link to comment
phren0logy Posted May 19, 2022 Author Share Posted May 19, 2022 OK, thank you for your help and prompt responses. If I wanted to run a deep hardware diagnostic do you have any suggestions? Quote Link to comment
JorgeB Posted May 19, 2022 Share Posted May 19, 2022 I would try with a different controller if available. Quote Link to comment
Solution phren0logy Posted May 22, 2022 Author Solution Share Posted May 22, 2022 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. 1 Quote Link to comment
