Disabling SMB auto sharing

Ciao!
I can’t turn off the auto sharing function for the attached USB memory stick.
I’ve tried

/disk settings set auto-media-sharing=no auto-smb-sharing=no
/disk set usb1 media-sharing=no

but I still get

Flags: D - DYNAMIC; X - DISABLED; * - DEFAULT
Columns: NAME, DIRECTORY, REQUIRE-ENCRYPTION, VALID-USERS
#     NAME  DIRECTORY  REQUIRE-ENCRYPTION  VALID-USERS
0  X* pub   flash/pub  no                             
1 D   usb1  usb1       no                  guest

Is there any other option I have to set?

I know I can completely disable the SMB feature, but it’s not what I’m actually looking for.

I’m using RouterOS 7.18.

Thank you!

Denis

/ip smb set enabled=no

But if that’s not what you want, have you already checked from an external device if those shares are still visible ?
It’s not because they show locally, they are being published.

Set default share on “lo” interface only.

/disk settings
set auto-media-interface=lo

By playing a bit with different boards, I noticed that the correct behaviour, that is, manual sharing partitions or volumes over SMB, works conly for microSD ports, while for all USB devices the auto sharing function cannot be disabled.
I can’t understand if it’s a correct behaviour or a some kind of bug.
