Hi. Just bought two HGST 10TB Drives. Drives seem to be working OK. Crystal Disk Info shows no errors. Looking to REGISTER these drives.

When I try to register these drives on WD Support, I get the response:
Please correct the following error(s): No results found.

Proof of Purchase = No File Chosen
I uploaded the both the Amazon.com Order pdf and the scanned Fedex Receipt from the seller

Once logged in, you’ll typically need to input information about the HGST drive you wish to register. This may include the drive’s serial number, model number, purchase date, and place of purchase. You can find this information on the drive’s label.
