I am a data forensic and recovery expert, and this is very common in my field. This is known as data scraping or data carving. There is specialized software which can look bit by bit (A BIT is a block of data on a hard drive or data storage) looking for "pieces" of data and putting it back together LOST or DELETED files from raw data. (An example of this is a product known as "TestDisk", and Law Enforcement/forensic analysts quite commonly use a software called "EnCase" or "Cellebrite". It is actually very rare to see data truly deleted unless someone really knows how to delete it. And even if you cannot reconstruct a file in it's entirety, you may be able to reconstruct a large viewable portion of it. Assuming there was EVER data on this device or "In the Cloud" (Which in itself is just a collection of storage drives and data storage), odds are they can recover something.as per cnn, they’re doing just that. they used a term that’s basically “scraping the layers” to retrieve the data. imo they’re using specific language because google is inundated with lawsuits regarding customer privacy, so they don’t want to outright say that they have data that’s not kosher
but that’s speculation in my part (though partially emboldened by cnn’s current reporting with the google/nest rep)
IMPO (In my professional opinion)
