How to put the server on USB HDD? i am on 2.1.54 thx

hi,
i am using 2.1.54 qt6 win10.
i was forced to stick on this version due to IOE.

I wanna locally sync to my own server.

i saw the examples for config,
but searched the posts that seems little one talk about putting it on external HDD using NTFS.

anyone have any ideas?
thanks

ps:
not very familiar with python, only use gpt4 to help.
