May 25, 20233 yr Hi all, it's been a while... While updating my sever from 10.x (can't remember which version) to 11.5. After the update the server wouldn't boot, and it appears that my flash drive is corrupted. Of course, I didn't follow the instructions and failed to create a flash backup before the upgrade, so I'm wondering if the upgrade process does anything to automatically back up the flash drive contents somewhere. It's probably a long shot, but my other choice is to restore to the last flash backup I have from 2018 and try to remember what I changed since then. If anyone has any tips for accessing a flash drive that Windows doesn't even recognize ("D:\ is not accessible. The file or directory is corrupted and unreadable."), I'm all ears. Attached is what I see on the console during server boot:

May 25, 20233 yr Author Thanks @JorgeB! Between chkdsk and those instructions, I was able to get the server back up and running. I need to fix a few things, but so far it looks stable.
