Reason for asking is I have a stack of HGST 2.5 drives that were all totally raw, no file system that had to be initialized and formatted. If the quick format (GPT) is used you get a HEALTHY (Basic Data Partition) immediately in Windows but partition 2 of that drive is still formatting. In this state if you eject the drive it's not recognized by SpinRite. So my guess is fully formatted is required. Yes or no.
