Thanks for the help!

To confirm I have avoided writing any new data to the array since the swap of disk 3. Old disk 3 was bad and had a red icon so I needed to be changed (it will be discarded). I added a new 3TB drive and moved the current parity to replace disk 3. Once that was completed I rebuilt the parity drive as part of the process. This all seemed to go as expected Can I complete the following knowing that some data on disk 3 may be corrupted? 1) Create a new config with disk 4 removed and setting everything else as it is now? E.g. parity WDC_WD30EFRX-68EUZN0_WD-WCC4N4US4V96 (sde) disk1 /mnt/disk1 WDC_WD30EFRX-68EUZN0_WD-WCC4N0482416 (sdc) disk2 /mnt/disk2 WDC_WD30EFRX-68EUZN0_WD-WCC4N0477615 (sdd) disk3 /mnt/disk3 WDC_WD30EFRX-68EUZN0_WD-WCC4N0460577 (sdb) 2) Start the array and complete a parity sync --> is this the same as a parity check?

At least that disk was only 1TB. What is the best way to remove the bad drive from the config? Disk 3 was rebuilt using the parity swap and I installed a new drive as parity. I have checked the data and been able to access all data in the array. That said I have not completed a parity check since rebuilding disk 3. Should I remove disk 4 from the config before completing a parity check?

Thanks for following up! Here is the smart report for sdf - disk 4. If I can provide anything else let me know. When you say corrupt rebuild are you referring to rebuilding data from disk 4 only? The reason I ask is the data rebuilt to disk 3 appears intact and accessible. Let me know if you can see anything or any opportunity to restore the file system to reiserfs?

Hello All, This is my first time posting here so if I have left out anything let me know. I am running unRAID version 5.0.5 and discovered an unformatted disk after a power loss (disk 4) (sdf). I booted the system once power was restored and found the disk in the unformatted condition. Also going to add that during this time I had another disk that had previously failed (disk 3) (sdb)and I completed that replacement first using the parity swap process here - https://lime-technology.com/wiki/index.php/The_parity_swap_procedure In general my question. Is there a way to attempt to recover disk 4 by updating the the file system? Currently it shows the file system as unknown and I am not able to use the disk. Screenshots and syslog are attached. I have the full syslog and can provide if needed. Is there a fix within this FAQ - 7.4 Why is a disk showing as Unformatted? I wanted to confirm with some experts before I attempt anything. https://lime-technology.com/wiki/index.php/FAQ#Why_is_a_disk_showing_as_Unformatted.3F If you need anything further let me know.
