Recently, some OWC customers have reported experiencing a situation where their new SSD will not show up in Disk Utility in High Sierra. Although Disk Utility should always be tried first, a Mac’s Terminal can be used to format the drive in these cases. These steps permanently delete all data stored on the drives that make up your Fusion Drive. Make sure that you have a backup before continuing.

Turn on your Mac, then immediately press and hold Command-R to start up from macOS Recovery.
