I was able to try the disk on another computer today and it would not mount either. Weird that it failed so early. I guess I have to RMA it. Thanks for the help.

Thanks for the quick reply. I swapped the cables but I'm still getting errors when trying to format via unassigned devices.

Hi Guys, I had a cache pool of 2 MX500 500GB SSDs running in Raid1. About a week ago my Docker containers stopped working and after logging in the webUI I found out that the Docker.img was corrupted because the pool had no space left at some point during the night, probably because of some download. At the same time, one of the drives in the pool experienced some SMART errors (Data attached). After having problems with btrfs before and btrfs scrub indicating uncorrectable errors I decided to delete the pool after transferring the data to the array temporarily and use the disks individually with xfs. One drive is working perfectly normal since reformatting and moving the files back. Unfortunately, the drive with SMART errors cannot be formatted, mounted or otherwise accessed. When creating a new pool via the webUI, the drive shows as "Unmountable: Unsupported partition layout" and after confirmation "Yes, I want to do this" the page is only refreshed, but it still shows as unmountable. As filesystem it now shows xfs, so some formatting did happen. To be clear, the data on the drive does not matter, as I could transfer it from the RAID1 pool, and everything is currently running fine on the other drive. I just want to be able to use it again with xfs as the new file system. Other things I already tried after some research: xfs_repair wipefs -af blkdiscard deleting and creating partitions via fdisk Formatting and Mounting via Unassigned Devices Having my roommate check the connections (I could not yet try another cable) Since i currently have no physical access to the system, i have not yet been able to try the disk on another computer. Any other ideas how to fix this? Has the drive just gone bad? Thanks a lot in advance. Diagnostics and SMART Data from today are attached, unfortunately the logs from the first event are gone, as I restarted multiple times since then.
