Add existing hard disk ans see all data

Hello, I'm newbie openmediavault user.
I would like to add my old personnal HD to openmediavault, share this HD to samba ans see all old data, no new folder share.
I dont see a gold reply.
For you information, i'm 16 years old and i want to lean more .
I now it is possible to create a new folder "share" and After add alias link in this folder but its only this bash script.
Thx

What filesystem is on that drive? What have you used it for?

NTFS, i used this HD with Windows 10 and i use OMV Raspberry Pi.
I think, i will create a new folder share in HD root and i will cut all my data in this folder
