By file system checks do you mean a SMART self test? If you are referring to a built-in diagnostics tool, where abouts will I find this? If so, see attached logs for DISK 1 and DISK 3 Thanks mate - I'll have a look into this, is it possible to automate this? I did read in the doc's that its best to stop the array before making a backup of the config. ST2000DM001-1CH164_Z1E4L0GQ-20190609-1925.txt ST2000DM006-2DM164_W4Z2XYVD-20190609-1928.txt

It's very possible I didn't which probably means files are gone... Never felt so stupid not backing up the flash drive itself. I'll just have to recover whatever I can find from the backups I guess 🤷‍♂️

I recently had the USB Flash Drive fail while moving houses, the USB was actually severed in half (see pic), so no way I was going to recover the necessary config files In summary I have 1x 60GB SSD Cache and 4x 2TB Drives, my understanding was once I've setup a new USB Drive this should've just come back online O.K. given it is a 4x Disk setup with 1x Parity... which it did to some extend except for Disk 2 (see below) Cache KINGSTON_SV300S37A60G_50026B723301B685 - 60 GB (sdf) - btrfs Parity ST2000DM001-1CH164_Z1E4L0GQ - 2 TB (sdb) Disk 1 ST2000DM001-1ER164_Z4Z0JPET - 2 TB (sde) - xfs Disk 2 ST2000DM006-2DM164_W4Z2XYVD - 2 TB (sdd) - Unmountable: No file system Disk 3 ST2000NM0033-9ZM175_Z1X5GSAQ - 2 TB (sdc) - xfs I've gone to Tools > Diagnostics and did an export of the disk having problems (see attached), I'm not very good at reading these output logs, can someone please help and point in the right direction as I can see chunks of data missing which will probably be on this drive. Please let me know if you need anything else to assist with this problem, happy to provide it ST2000DM006-2DM164_W4Z2XYVD-20190609-2316 disk2 (sdd).txt
