@Christopher (Drashna) I also have the same issue, with a Sabrent 10-bay device, connected over USB-C. All drives are being scanned at the same time, and I'm getting 3 dropping from the pool during the scan. Weird part is, checking the controller view, 4 are on separate "USB Attached SCSI (UAS) Mass Storage Device" while 3 are on the same "AMD USB 3.10 eXtensible Host Controller 1.20 (Microsoft)" controller. And 3 are not visible on the pool anymore - power cycling those bays or resetting the computer would probably make them visible again though. Is there any way to force only a single disk to be scanned at one time, regardless of number of controllers? A global setting for 'cap max concurrent scans to 1 disk' might solve this issue with multiplexed USB enclosures.
