April 3, 20242 yr Situation 3 Disk + Parity Array One of the disked 'failed'. I believe this is due to a SATA controller issue. I move the failed drive to another controller. The drive showed as unusable, but could be formated formated the drive drive is formated, but still a red X beside the drive and no rebuilding of the data.
April 3, 20242 yr Community Expert The procedure is https://docs.unraid.net/unraid-os/manual/storage-management/#rebuilding-a-drive-onto-itself But... you NEVER format a drive you need to rebuild, there are plenty of warnings about that. Now you can see the emulated drive is empty since it was freshly formatted. Hopefully the data is still on the actual drive. What is the exact situation now, is the drive connected, is it assigned to the array? Do not do anything else. Edited April 3, 20242 yr by Kilrah
April 3, 20242 yr Community Expert If formatted or not, does not matter. If the emulated drive still shows the old contents, follow the mentioned procedure PRECISELY and the old drive will be rebuild in place. Nothing lost.

April 3, 20242 yr Author Thank You ALL How do you know that it was the emulated disk from the screen shot? Also, all of the data is backed up. Trying to get the server stable from used parts, so at this time, it is a clone, and a learning box. Edited April 3, 20242 yr by kcossabo

But @itimpi is right, the physical drive could still have the data. In this case you have to use a different procedure. But first check the drive with unassigned devices.

Yeah, one nice feature of UNRAID: even if you do it wrong, usually there is a way to recover without loss. So in your case, you need to delete the array config and reassign all drives like before again. parity needs rebuilding (because of your format action) read about "new config" in the manual. it is the same like you did at the beginning. Hint: write down the serial numbers of the drives before. Use the same ones for the new config (don't put a data disk as parity or vice versa!!!)

When using New Config I nearly always recommend using the option to keep all assignments so serial numbers do not need re-entering. You can then make changes (if any are required) from that position. Minimises the chance of error.
