well....turning it off and on again actually worked! Rebooted the server, started the array, formatted both disks and this time they formatted succesfully - thanks for the assist.

Unraid can't format them. Tried from the Format button after monuting them, but it does nothing. I only attempted to use partition 2 in the cli as an example of two different errors, to show it thinks it has a writable file system, however they don't format and cannot seemingly be rapired either. As stated, as a test i removed them from unraid (plus all trace of them from historical devices) formatted and tested in Windows and they work perfectly, no SMART errors either so i know the disks are working. Plug back into Unraid, mount (no pre-clear options) set as xfs FS and they immediately come back as Unassigned Unsupported or no file system. This is also setting them up under new Pools As you can see from the screenshots both discs don't have any partition format info

sorry, should have mentioned i also tried the 'partition' and that garnered same results. ~# xfs_repair -d /dev/sdc1 Phase 1 - find and verify superblock... bad primary superblock - bad magic number !!! attempting to find secondary superblock... ...Sorry, could not find valid secondary superblock Exiting now. --------------------------------------- ~# xfs_repair -d /dev/sdc2 xfs_repair: /dev/sdc2 contains a mounted and writable filesystem However, the drives don't appear to have partitions

Hi all, Very strange issue with x2 of my drives Both cache - 1 SSD 1 NVME Both drives, within a day of each other changed to Unassigned Unsupported or no file system Unmounted, erased, mounted, formatted (which fails) etc Removed both from the array and deleted the pools Removed from historic devices Rest of the array works fine Took both drives and tested and working perfectly in a Windows machine - no disk errors, SMART issues. Added back to the unraid server ,set format to BTRFS - no change Erased and changes to XFS - no change Attempted reapir on both disks whilst in XFS of: xfs_repair -d /dev/sdc Phase 1 - find and verify superblock... bad primary superblock - bad magic number !!! attempting to find secondary superblock... xfs_repair -d /dev/nvme0n1 Phase 1 - find and verify superblock... bad primary superblock - bad magic number !!! attempting to find secondary superblock... i'm now at a loss, both discs ar eworking perfectly but unraid will simply not accept them.
