September 13, 20232 yr Unraid 6.11.5 running on QNAP TS464. All in a sudden, Unraid threw me an error saying flash drive is corrupted and license key is missing. Unplugged the USB flash drive and tested in two different computers, both can successfully read the drive without any issue. Went back to Unraid, even with the USB flash unplugged, in the Main page I still can see the flash drive there. Clicked it to view and saw nothing in it. Plugged the USB flash drive to a different USB port of QNAP, the flash drive can be detected successfully as an unassigned device. The flash drive is still frozen in Unraid. Is this a hardware problem or software problem? How to get Unraid to detect the flash drive again? Thanks. eddie-nas3-diagnostics-20230913-1401.zip Edited September 13, 20232 yr by eddie_bear
September 13, 20232 yr Community Expert Try rebooting, you cannot reconnect the flash drive on a running server.
