[solved] fdisk exits with 'illegal seek' error, but not on listing

I'm trying to install Arch on a new system using a cd image from 2022-11-01. The system works fine in Windows and this is meant to be a dual-boot setup. I left space for Arch during the Windows installation (no hibernation or fast boot) but when running

fdisk /dev/nvme0

fdisk immediately exits with this error:

fdisk: cannot open /dev/nvme0: Illegal seek

. cfdisk same result. The

/dev/nvme0pX

entries are there.

The drive is a Samsung MZVLB512HAJQ-000L7 with a gpt disk label, using a Thinkstation Xeon W board.

fdisk -x

and

lsblk -f

all work fine in listing the drive details and current partition layout. dmesg shows no errors relating the drive nor after running the commands. There is no disk password set and any security setting I could find in the BIOS is disabled with no result.

How can I fix this?

Are you sure you don't have a namespace? i.e. nvme0n1? Can you post a dmesg/generally the output of fdisk and the like? https://wiki.archlinux.org/title/List_o … n_services Do you potentially have RAID mode enabled in your UEFI and what happens if you switch that to AHCI?

Doh... The namespace bit was it.
