Hey folks I picked up the new MacBook Air and was planning on using it in conjunction with a 2TB Samsung T5 SSD external drive. The new default for Disk Utility Show Only Volumes (a formatted partition of a drive) as seen below keeps the SSD from being seen. From the utilities window in macOS Recovery, select Disk Utility and click Continue. The order of repair in this example was Macintosh HD - Data, then Macintosh HD, then Container disk4, then APPLE SSD. Keep moving up the list, running First Aid for each volume on the disk, then each container on the disk, then finally the disk itself.
