Thank you! Parity is valid. Are there any specific steps to emulate the disk? I ask because when I’ve had drives fail it emulates automatically.

It was previously connected to a Raid controller. I actually followed some of your other suggestions in previous threads and had to do data rebuilds on my other drives. My other 4 drives rebuilt no problem, just took about 8 hours a piece, but for some reason this one says active, normal operation and unmountable after the rebuild.

I recently moved my drives to a new server and one of my disks is not mounting "Unmountable: Unsupported or no file system" I have attempted to xfs_repair -L /dev/md4p1 but all I get is Phase 1 - find and verify superblock... bad primary superblock - bad magic number !!! attempting to find secondary superblock... and then endless periods (......... etc) Am I out of luck? here are my diagnostics alecstormz-diagnostics-20241105-1239.zip I ran fdisk -l /dev/sdk Disk /dev/sdk: 5.46 TiB, 6001175126016 bytes, 11721045168 sectors Disk model: WDC WD6003FFBX-6 Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: gpt Disk identifier: DFC2B7FF-66A4-4612-838E-DF3498F945C9 Device Start End Sectors Size Type /dev/sdk1 64 11721045134 11721045071 5.5T Linux filesystem and I ran blkid /dev/sdd1: LABEL="easystore14" BLOCK_SIZE="512" UUID="BCE44B73E44B2F48" TYPE="ntfs" PARTLABEL="easystore" PARTUUID="08dec140-4c3d-40b9-bb67-55780231c5aa" /dev/sdb1: LABEL="easystore12" BLOCK_SIZE="512" UUID="62DA13FCDA13CAE5" TYPE="ntfs" PARTLABEL="easystore" PARTUUID="29d3e6a5-5bfb-4303-95e7-c2ca993819c1" /dev/sde1: LABEL="easystore18" BLOCK_SIZE="512" UUID="9094D9D194D9BA44" TYPE="ntfs" PARTLABEL="easystore" PARTUUID="9c53af12-0f47-46d5-8726-44acd7ed7cd3" /dev/sdc1: LABEL="My_Passport" BLOCK_SIZE="512" UUID="F474B7AA74B76DCC" TYPE="ntfs" PARTUUID="98b2df82-01" /dev/sda1: LABEL_FATBOOT="UNRAID" LABEL="UNRAID" UUID="2732-64F5" BLOCK_SIZE="512" TYPE="vfat" /dev/loop1: TYPE="squashfs" /dev/sdf1: UUID="a4075403-34b9-4c9d-a300-f5b52dfc81b5" UUID_SUB="ef79d78c-2793-4ae8-a6c3-e729c054b70a" BLOCK_SIZE="4096" TYPE="btrfs" /dev/nvme0n1p1: UUID="a4075403-34b9-4c9d-a300-f5b52dfc81b5" UUID_SUB="a5157f58-37ae-46a9-93ad-a8fad727de0f" BLOCK_SIZE="4096" TYPE="btrfs" /dev/sdi1: UUID="41345b43-42a1-43fe-adde-c6bbc0aebcb1" BLOCK_SIZE="512" TYPE="xfs" PARTUUID="bcffc674-6b50-4d88-8532-7a908fe1ed45" /dev/sdg1: UUID="fb92734c-0777-4d4b-bd41-f8cc9f40eb27" BLOCK_SIZE="512" TYPE="xfs" PARTUUID="955a34c5-c8ca-4e78-90e3-0987f7a4489b" /dev/loop0: TYPE="squashfs" /dev/sdj1: UUID="2f1f49f0-da75-43fd-b4e6-4ed604ff534a" BLOCK_SIZE="512" TYPE="xfs" PARTUUID="0486784c-f748-4394-900c-e3e8feb4f9d0" /dev/sdh1: UUID="fce2b400-bda0-4fed-814a-b7f50a85a5d6" BLOCK_SIZE="512" TYPE="xfs" PARTUUID="704d604a-f864-443f-98c5-f59270ea1ce3" /dev/md2p1: UUID="fb92734c-0777-4d4b-bd41-f8cc9f40eb27" BLOCK_SIZE="512" TYPE="xfs" /dev/md1p1: UUID="41345b43-42a1-43fe-adde-c6bbc0aebcb1" BLOCK_SIZE="512" TYPE="xfs" /dev/md3p1: UUID="2f1f49f0-da75-43fd-b4e6-4ed604ff534a" BLOCK_SIZE="512" TYPE="xfs" /dev/sdk1: PARTUUID="50a4ecc7-6c1f-4b83-ae4d-78b3ac040cb5" /dev/loop2: UUID="51a4be1c-948f-4bb0-9c4a-68fb26850e99" UUID_SUB="dba694f8-5db4-46e7-8aa8-8621ef084775" BLOCK_SIZE="4096" TYPE="btrfs" /dev/loop3: UUID="4e4da922-889e-449e-b64f-681514fe10f9" UUID_SUB="098e8ed9-bb30-4dd4-814e-ae2ea6adefb6" BLOCK_SIZE="4096" TYPE="btrfs" Thank you for any assistance!
