DIR-835 smb share issue

Hello, I new to openwrt and I am using the 23.05.5 on a DIR-835. I tried to follow some of the steps

I could not install luci-app-samba4 because I don't have enough storage.

I did add a user via the SSH. I installed several packages.

Under System-> Mount Points
image

Services-> Shared Directories I added Name: Usb Path: /mnt/sda1/

When I click on the usb folder in the router in windows explorer I get a Windows cannot access the folder. Error code 0x80070035.

I checked and tried from things from Need Help for setting up NTFS USB Drive using SMB for Windows usage - #30 by nextnomura

I searched online and tried to install windows sm1 and I still have the same problem. Please.

can you list the content of /dev/sda1 from the router itself ?

what is / in your screen shot ?
the share name ? if that's the case, it's a bad one.
the mount point ? then it's equally bad.

Thank you. How do I list the contents of /dev/sda1?

The / in the screenshot is the moint point. I changed to the /mnt/sda1/. Let me know what it should be please?

Now I can get into the usb folder but the folder is empty.
