One more question if you don't mind. Emulated disk 5 seemingly has a large amount of data in lost+found. The folder is ~460gb according to the webgui. Do you have any recommendations on how to go about recovering that data?

Got it, thanks for the help! I have a replacement drive arriving this week and I'll rebuild once I get that installed.

Ran check on the emulated disk 5. It found errors and I ran the repairs. I started the array in normal mode after and the emulated disk 5 appears to be mounted now. Attaching diagnostics. plexserver-diagnostics-20251220-2148.zip

I followed the steps and here's the resulting diagnostics. Thanks again for the help. plexserver-diagnostics-20251220-1945.zip

Here's a couple diagnostics, one from today and one from last week when the problem started. For reference, disk 3 is the one that won't mount, and disk 5 is the one that has SMART errors and was about to be replaced.

Helllo UnRaid community, One of my drives recently started giving me some SMART errors. It's a drive I had been meaning to upgrade for a while, and I have a new disk on the way to replace it. A day or two after that started, a different disk suddenly started failing to mount. It shows "Device disabled, Contents emulated" and "Unmountable: wrong or no filesystem". However, I can't access any of the emulated contents. I have 6 total drives, with only one acting as a parity drive. I have tried to recover the filesystem both through the webgui and the command line. Each time I receive an error stating "xfs_repair: libxfs_device_zero write failed: Input/output error" during phase 7 and it fails. My understanding is that these were trying to repair the emulated filesystem, so I also tried running xfs_repair on the raw disk (/dev/sdf). It ran for a good 12 hours and then said something along the line of "failed to find secondary superblock". I was also due for a PSU upgrade on this system, and considered power issues as a possibility, so I have replaced the PSU, and tried different SATA cables, and the errors persist. I ran an extended SMART test on the disabled disk and it came back OK, attaching the results here. What should my next course of action be? The new disk should arrive early next week. Should I wait until that arrives to attempt recovery with something like ddrescue? None of this data is critical, but I'd still like to at least minimize data loss. Any advice is appreciated. Thank you in advance! WDC_WD60EZAZ-00SF3B0_WD-WX52DC1A4E93-20251214-0846.txt
