I have a USB dockingstation (2 harddisks). I'd love to add these as unassigned device. Somehow does not seem to be possible? No disk shows up as unassigned device. I tried various disks (formatted NTFS and XFS), but nothing works.

 

Curious whether this is even possible? If so, what do I need to do? Attaching diagnostic log. Thanks!

Can drives be either XFS or NTFS? Can I plug in/out the disks or does it need to be connected when starting Unraid?

Before thinking of that I would worry about disk13 read errors:

Looks like a connection problem.

My connection issue is the reason why I am looking for USB. I'd like to test something by shifting disks to USB. This will allow me to understand what's really happening. I keep having connection issues for many years and never found a sustainable solution.

 

Any thoughts why my USB disks are not showing up?

Harder to find when the log is full with other issues, reboot and after array start connect the USB drive, then post new diags.

Thanks. I removed disk 13 and rebuild the array (without parity). Now only 14 disks as I removed 2 for trouble-shooting. I plugged in the USB after starting the array (only one USB disk to keep things simple). I refreshed UD, but doesn't show up. Any thoughts? Thanks for your help!

There's a problem detecting the USB device even after multiple tries:

Try a different port but it's likely some problem with the enclosure itself.

Got it. It does work with my notebook, so the USB dock is per se not broken. It may not be compatible with Unraid / Linux though?

Possibly.
