The Music folder on the BM5 is meant to be writable. That’s how BeoConnect adds music. The "Read-only" box doesn't matter. However,
- The share is hidden. It won’t appear under Network. In File Explorer, choose Map network drive and enter <code dir="ltr">\\<IP of your BM5>\bm-share$ (with the <code dir="ltr">$). You can find the BM5’s IP in its network settings menu. Maybe you already did this?
- Windows 11 has SMB1 turned off. The BM5 runs an old embedded Windows and only speaks SMB1. Windows 10/11 disable it by default, which is why BeoConnect and drag-and-drop fail. Go to Control Panel → Programs → Turn Windows features on or off, tick SMB 1.0/CIFS Client, and possibly reboot
You can also rip out the HDD from the BM5 and connect via SATA/USB as a last resort :-) Or convert to bs5c!
