The Impossible Drive

When I was hired to recover data from one Hunter Biden’s liquid damaged laptops, I was successful in recovering a reported 300GB of data.  Of that data about 220GB was visibly accessible while the remaining data consisted of invisible, inaccessible and cloud related files. When Hunter failed to collect and pay, the laptop became my property. On August 28th 2020, mailed a copy of the drive to Rudy Giuliani’s office.  The drive was 60% full with a little less than 200GB remaining.    
 
In recent days I have heard discussions in reference to an additional 450GB of data recently recovered from a copy of the laptop.  A copy based on a drive that supposedly was in my possession over a year and a half ago.  I can not speak to the chain of custody for the drive in question, but I can state that I doubt that it i s identical to the copy I created. There are two glaring issues that lead me to believe that the drive in question is not a faithful representation of the original.  
 
First, it is technically impossible to recover 450GB of erased data from a 500GB drive with only 200GB free.  When you delete a file from a computer, you are basically telling the computer to forget the location of that file on the drive. It is possible to recover a deleted file as long as the computer hasn’t decided to write new data to that file’s previous location. If 450GB of data was un-deleted from the drive, that would leave 250GB of data recovered beyond the original 500GB drive capacity. The newly discovered 450GB of data combined with the existing original 300GB data would require the original copy of the drive to be at least 750GB.  The original copy was only 500GB. 
 
My second concern is that there have been multiple forensic examinations of the drive over the past year and a half. These examinations were not just to verify the authenticity of the data on the drive, but also to inspect the drive for any tampering or any compromise in its integrity. All examinations have revealed no signs of tampering and the integrity of the drives are intact. None of these examinations have ever revealed deleted or invisible files remotely close to the size of the newly discovered data. If there was an additional 450GB of data hidden on that drive, we would have heard about it before now.  

The serial number collected by the FBI shows the drive is only 265GB.
