So, if I'm right I should
1. install Data Migration and Magician.
2. Connect the ssd via a USB to SATA adapter, even if the adapter appears to starve the SSD for current.
3. Run Data migration and trust the results presented.
4. Stop the computer as correctly as I can
5. Disconnect the SSD, Open the computer chassis, Swap the SSD for the HD installed. Assemble the chassis and then connect and start the computer. It should start up and let me log in.
6. Start Magician and see what it thinks of the SSD.
