First issue with Unraid Plus for me. Can't add 10th data drive. It finished pre-clear successfully and shows unassigned. When I try to assign it it fails. Error in log is already assigned. but it isn't assigned. It sits in unassigned. What is my next stop. Diagnostics attached. Thanks,

Your problem is the USB enclosure you're using it's reporting the same serial for several disks:

To be honest I don't know how you got the other 3 working.

 

 

The other 3 are in a different usb enclosure. This is the first drive in a new usb enclosure. I've been using Sans Digital but this one is mediasonic but looks just the same...

So I need to buy a different vendor enclosure? Recommendations? Sans Digital has been very reliable for me.

My recommendation would be not to use USB enclosures, if you really need external use a SAS enclosure.

Thanks
