Thanks for your help. blkdiscard -f was the command needed to get the drive back into a working state.

Ah mounted it to pull the data. Will unmount and try again. The gui just cycles over and over, doesnt give too much to go on.

New diag attached. Re did commands above and then tried to format drives but unsuccessful. unraid-diagnostics-20260313-1823.zip

Have tried that. Even did a new config.

How do I get unraid to accept the disks as brand new like they've never seen them before?

How would that break the pool and btrfs? I tried to just go nuclear and did the new config and wiped the disks but it still won't mount the drives. This is as a brand new pool with wiped disks but it just loops and asks to format the drives over and over. It's like unraid has blacklisted the disks? unraid-diagnostics-20260311-2053.zip

OK, so that has at least allowed the fs to mount but I think the 54GB is correct as thats what it was originally before all of this. Not sure what the extra 30GB is? Or I could be wrong. Things aren't working though as docker wont start. unraid-diagnostics-20260311-0913.zip

So I can successfully mount /dev/sdh1 from the unassigned device and browse this. But mounting /dev/sdg1 give this error: Mar 11 00:49:44 Ragnarok unassigned.devices: Mounting partition 'sdg1' at mountpoint '/mnt/disks/S2R9NX0J522893R'...

Even if I redo the Pool on reboot it has a mare: 19Z was in slot one whenever I create the pool and then on reboot it says it is wrong because it drops that disk completely on array start up. The "wrong" is wrong or more so unraid is very confused.

Initially had what looked like a faulty sata cable, removed the disk and re-balanced back to the one disk. Have replaced the cable and on adding the drive back in, it's all turned to custard. Initial steps were: Re-added drive to appdata cache pool, prompted for a format of the disk. Ticked Yes. Array started and says the appdata cache pool is unmountable/readable fs. I thought it should automatically pick this up and set it up as raid1, it's done this for me in the past. Assume it as a v7 bug, which on googling looks like it might be? Rebooted the array and then got this: Wrong Pool State appcache - too many wrong or missing devices Found a few posts about this to remove the pool and re-add it back but in doing so when the array starts, it just comes back with no drive found in the 2nd slot(the original good disk with data) which is assigned to slot one but shows as missing from slot 2. If i remove the pool again, I just get the same.

Also occurs for 6.12.15 Flagged all my Array shares with this error. As suggested dummy change fixes it.

I'll do a manual disconnect and grab logs again.
