Hello @Randall ,
Welcome to the forum!
You can follow this guide: How to migrate the Windows GUI node from one physical location to another? - Node Operator
Since it’s the same PC, you do not need to share disks. It would be simple as (cmd or PowerShell):
robocopy /MIR D:\storagenode E:\storagenode
Just need to repeat this several time while node running until the difference would be negligible, then stop a service (elevated PowerShell):
Then run the robocopy command one more time to copy remaining pieces.
Modify a path to data in the config file: How do I change values like wallet address or storage capacity? - Node Operator and allocated space, save the config (menu File - Save, it could ask for administrative rights, confirm and click menu File - Save again), then restart the storagenode from the elevated PowerShell:
Then check your dashboard and make sure that all data in place. Otherwise stop the storagenode service and check your path.
Please also check your logs: How do I check my logs? - Node Operator
I would not recommend to use WiFi for network connection for your storagenode - you likely lose the race for pieces more often than others, because WiFi is not designed for massive data transfers or access to storage.
