Then I did another clean reinstall, migrating only User Data over (no Applications or Network Settings) to see if this would fix it. I retired the other older WD drive (firewire connected via a Thunderbolt adapter). Griffin replaced the G-Drive Pro Thunderbolt along with a new Thunderbolt cable under warranty. So replaced both with new USB external drives. Problem persisted with random shutdowns when external hard drives were mounted. They could find no hardware issues with the iMac. cleaned up) the iMac Fusion Drive, redid the clean install, and tested both external hard drives, reformatting one of them (at some cost). eventually bringing the iMac into my Apple Service Provider, along with the external hard drives I used for backups, both of which were connected via the Thunderbolt 1 interface (one of them via a Thunderbolt to Firewire adapter).

However, the spontaneous ejection problem has now returned on a USB 3 connected drive, which had previously been totally stable. The cleaned G-Tech drive has been stable for the last three weeks or so.

I transferred back to the reformatted G-Tech drive the folder contents from the WD drive and felt confident that an accurate transfer had occurred, so just did a few sample checks (Cost 1 man-hour).

I reconnected then erased the G-Tech drive using Disk Utility (whatever happened to Format?).

I changed to drive power supply to a spare that I had in store.

I bought a new Thunderbolt 2m cable and reconnected the G-Tech drive (which only has a Thunderbolt connection).

I then manually checked that every last byte had been accurately transferred. This was a time consuming process as I had to let the transfer process run for as long as possible before a spontaneous ejection occurred and then pick up again from where it crashed.

I transferred the folder contents of the 8 TB Thunderbolt connected G-Tech drive to the new WD USB 3.0 one.

I purchased a new external 20TB WD hard drive that connects through USB 3.0.
