Thanks for the tips. I rebooted the LS with the drive attached but it didn't help. Its an external powered USB drive.
Also, some further information. I bought a second SATA enclosure. Completely different make and model. Same problem. But I have now noticed that the enclosures are being recognized. If I look on "System status" > "USB details" I see the two enclosures appear and disappear when I plug/unplug them.
USB class > Manufacturer > Device Name > USB 2.0/2.1
==========================================
Storage > Generic > External > USB 2.0
Storage > JMicron > USB to ATA/ATAPI Bridge > USB 2.0
However, as before the "USB Disk 1/2" says disk is "Disconnected"
Any more thoughts? It looks like it should work..
Damon.
