To resolve this you'll need to reset it using a computer.
If the Nest drive is successfully showing up on your computer, can you see a technicalinfo.PLIST file? If you get this far let me know and I'll ask a community specialist to assist with next steps, as these can't be shared publicly in the community.
Thanks for letting us know, @rmrmrmrm. We'll leave the thread open for a few more days until you get home to try the steps again. But please don't hesitate to give us a shout if you need more questions, and we'll look forward to your response on how it goes.
Thanks for assisting, Edward.
