Disk usage graph discrepancy in v1.69.2

when v1.69,it told me 1.3tb when i hover mouse above graph

i check my all databases,and it`s all right.

will its because of im in china, the country firewall prevent some connection, so it happened?

It should not. What’s filesystem on this drive?
And did you check it with Earnings calculator (Update 2022-12-08: v12.3.0 - Now compatible with node version 1.62+ - Detailed earnings info and health status of your node, including vetting progress)?

Also, when you check databases, there should not be / before the Windows path, otherwise it will try to create databases with a such name and of course newly created databases will not have any issues.
So please replace /G:\ with G:\
