Thank you very much for the explanation - its a bummer but at least I understand the reasons. In my scenario after parity rebuilt, the drive was identical to the previous and the repair had the same result. I'm currently going through the lost+founds - my biggest fear of course is that the files in here could be incomplete. I haven't seen any evidence of that (most of these files were movies or tv shows), and although individual files/seasons may be missing, anytime a file is there it appears to be complete. I am hoping that the repair tool would only put files here that were intact so I can trust them without having to watch them all haha. I am in the process of implementing better backups to prevent the sting of something like this in the future. I'm still not sure how this happened since there was no unclean shutdown and the drive was fairly new and precleared. It even seems like I can use the drive that failed again after another preclear - would that be a bad idea in your opinion? I attached my logs in case it helps anyone else. Thanks again for explaining everything to me. unraid-diagnostics-20220325-1501.zip check-2

Hello, I woke up this morning to a bunch of movies missing from my media library and I noticed one of my drives was unmountable. I attempted the repair steps and it sort of completed successfully, but the lost+found folder had tons and tons of files and some without any extentions, so I really didn't trust the drive contents anymore. I stopped the array unassigned the disk, swapped in a new drive, and parity is in the process of building. But even though its writing, it still says the new disk is unmountable. I was hoping that after parity that would be fixed but I'm growing less confident as I read about this. Is this a scenario where Parity won't be able to help? Would parity rebuild with the unmountable disk, effectively erasing the backup of the dead drive? Or would parity stay intact and allow me to replace the unmountable drive and save the contents? I'm very nervous about a scenario where a disk died and parity is no help, so I'd appreciate any info.
