I was able to resolve this via pulling the drive out and running it in Windows Disk part with just the Clean command. Honestly should of tried this sooner but I assumed that something similar was being done initially when you hit the "Format" button. Why is this not the case? Also what would the Linux equivalent be to DIsk Parts "clean" command which removes all volume and partition data and uninitialized? Thanks

Here is the .zip, are you looking for a specific section? Happy to post that in text if so. Thank you EDIT: The syslog had some personal info after browsing.. Here is what I found, if there is something else that could help please let me know... : mkdir -p /mnt/cache Apr 24 21:33:21 Tower emhttpd: shcmd (5553): mount -t xfs -o noatime /dev/sdb1 /mnt/cache Apr 24 21:33:21 Tower kernel: XFS (sdb1): Invalid superblock magic number Apr 24 21:33:21 Tower root: mount: /mnt/cache: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error.

blkdiscard: cannot open /dev/sdb: Device or resource busy

Any assistance is appreciated. I am evaluating Unraid as a potential NAS / VM & Docker host solution for my home lab. I have a few drives in (just as a trial concept) and my 250 GB WD Blue SSD which is set as a cache device will not format. All I keep seeing is "Unmountable: not mounted" Things I have tried: Format with "File system type" set to Auto, xfs, btrfs Stopping the array, stating and trying again Different port on mobo & new sata cable Tried blkdiscard blkdiscard: cannot open /dev/sdb: Device or resource busy Drive is verified functioning when I plug it into an external dock to my windows box. Any assistance is appreciated. Update: I was able to resolve this issue after pulling the drive and running it through Disk Part with the "Clean" command using an external docking station with my windows box. Steps: 1.) Install drive into computer or use external dock to mount 2.) Hit Window + R and in the run box type diskpart than hit ctrl+shit+enter 3.) In the new terminal windows type List Disk 4.) Select your disk typing out the command select disk X where X is your number of disk, be careful not to select your operating system or other disks. 5.) Type clean 6.) Type exit. 7.) Remove the drive and re-install in Unraid box. I hope this helps someone else.
