Thank you for responding @itimpi, good point. I think my issue is now resolved. Turns out my Flash drive was read-only. I wasn't able to run error check via Windows (I kept getting the device is write protected), so I followed the instructions for replacing my Flash drive (restoring from a backup & transferring my license). I was then able to select the replacement drive, start the array, and am now waiting for the rebuild to complete. 🤞

The system notified me last week there was a smart error on Disk 4 of my array. It automatically disabled the drive. I shutdown my system, installed a new drive (of the same size), and precleared the new drive without issue. The new drive shows up as an option for Disk 4 but after selecting it, the screen flashes and the assignment is cleared. Any help would be greatly appreciated.

@SimonF You were correct. I was able to verify with your steps above that it is the ASMedia device. As a result, I'm also able to add it via USB Devices. Thanks again to you both.

Success! @ghost82 Setting the controller number to match the index worked. I obviously overlooked that when looking at other examples. Thank you very much. @SimonF For (my) learning sake, I had originally tried "lsusb" but did not see it listed.

I am still new to Unraid. I have a USB ASUS BW-12D1S-U Blu-Ray burner I would like to passthrough to Windows 10 VMs. It does not show up among USB Devices in the VM "Form View" (which isn't surprising after having read a couple forums based on similar questions). When checking "System Devices", it shows up in "SCSI Devices". I confirmed its name, bus, target, & unit via the lsscsi command in terminal. Based on the same forums, I edited the XML by adding a new entry within the <devices> </devices> block. The VM boots fine and a new SCSI Controller was detected within Windows. Attempting to update its drivers via the virtio ISO added a "Red Hat VirtIO SCSI pass-through controller" but that was it. Currently I have 3 SCSI Controllers listed in "Other devices" but have not been able to find any drivers. I'm running Unraid v6.9.2. Any guidance would be greatly appreciated!

Figured it out. Turns out the flash drive was in the wrong format (exFat). Reformatted it as Fat32 and works like a charm. Thank you anyway.

I did but same results.

About 3 weeks ago I built a new home server, ASUS AM4 TUF Gaming X570-Plus motherboard, and started a trial of Unraid. Today the flash drive I was using while initially testing appears to have died. I already purchased a new flash drive to use after I purchased a license. I have a backup of my config I used with the Unraid USB creator and am having trouble booting since the prior flash drive died. I have 2 USB boot options in the BIOS: USB (15.3GB) UEFI: USB, Partition 1 (15.3GB) Booting to "USB (15.3GB)" results in: "ExF Remove disks or other media. Press any key to restart. " Booting to "UEFI: USB, Partition 1 (15.3GB)" results in a blank screen (no cursor). After the BIOS splash screen, Unraid never actually loads. The web GUI is not accessible and I cannot ping the server. To test: I tried creating the bootable USB with "Allow UEFI" enabled and disabled (though I'm pretty sure it was enabled in my original setup) using my backup. I tried a different flash drive. Tried booting flash drives from different USB ports. I tried a "clean" install, not using a backup, and am having the same results. Any help would be greatly appreciated.
