You're starting with a 500GB 970 Evo and upgrading to a 2TB 970 Evo Plus. When installing the larger drive, it doesn't appear in Device Manager beyond the general Disk Drives section. Your first action should be to check the drive's status using Disk Management or another utility to confirm it's detected properly. Regarding transferring data from your motherboard without additional hardware, it’s not feasible—you’ll need a dedicated external drive or a compatible interface for that purpose.
