That seems to have worked, thanks! I'll be making a backup this time, so as long as the change persists I think I should be ok from here.

oops, missed one: root@BlackPearl:~# wipefs /dev/sde1 DEVICE OFFSET TYPE UUID LABEL sde1 0x0 xfs 56d319b6-e333-49dc-8aeb-5f59bc102f7e sde1 0x44000 zfs_member 16696117445970530796 disk2 sde1 0x7470b44000 zfs_member 16696117445970530796 disk2 sde1 0x7470b84000 zfs_member 16696117445970530796 disk2

Assuming I just type that into the Unraid terminal in the web ui - though I'm not sure if I did it right. root@BlackPearl:~# wipefs /dev/sdX1 wipefs: error: /dev/sdX1: probing initialization failed: No such file or directory root@BlackPearl:~# wipefs /dev/sdX2 wipefs: error: /dev/sdX2: probing initialization failed: No such file or directory root@BlackPearl:~# wipefs /dev/sdX3 wipefs: error: /dev/sdX3: probing initialization failed: No such file or directory root@BlackPearl:~# wipefs /dev/sdX4 wipefs: error: /dev/sdX4: probing initialization failed: No such file or directory

After following the guide and mounting all drives as data drives, they are all showing up as unmountable - unsupported or no file system. Is there a way to fix that without formatting the drives?

Hello, my old flash drive broke and I had to replace it, but the guide says that if I can't remember how my drives were assigned I should make a forum post. How can I make sure my data isn't lost?
