Woke up this morning to find my shares unavailable, the GUI had reverted to the light theme, and my flash drive showing under both Flash and Unassigned Devices. Did a clean reboot through the GUI, it wanted to start a parity check, and then the system locked up at about 2%. No errors on the screen. Only option was to force reboot. Same thing happened; obviously an unclean shutdown was detected so a parity check was triggered, and the system locked up at about 2% again. Shutdown the box, swap the flash drive for a brand new one after testing it, and the same thing happens again, right around the 2% mark of the parity check. Reboot one more time, left the array down, and downloaded diagnostics, which are attached. Temps are fine, no errors in syslog, and I cannot see anything that could be causing this. Was thinking of leaving everything else in my network that uses the unRAID shares offline and starting up the array with a parity check again, but wanted to post here first. Any/all help is greatly appreciated.

It just happened again. This time with the array stopped and literally nothing happening. I made no changes and didn't perform any actions.

Ok, oddly enough it just recovered without me doing anything. Attaching new diagnostics, but I think the most relevant thing is the following from the syslog:

This would mean that your flash drive dropped offline, then re-connected itself.  Try a different port.  Ideally USB2

That's what I was thinking, but wanted to post here first since I've already rebooted a few times. Will try another port and see what happens. This system only has USB 2.0.

Alright, swapped USB ports, brought it online, mucked around in settings and whatnot for about 20 minutes to get it to read and write to the flash drive and it's been stable so I started the array. Array came online and did NOT require a parity check so that might be a better sign that things are ok. I'll take it slow with starting up other services on the network for now.
