I have a USB drive mounted to /media/usbdrive on my Ubuntu 20.04 box. I can write files to any share except the root share. Meaning, I have these shares set up in smb.conf:

[usb]
path = /media/usbdrive
valid users = @samba
force user = shareuser
writable = yes
read only = no
browseable = yes

[apps]
path = /media/usbdrive/Apps
valid users = @samba
force user = shareuser
writable = yes
read only = no
browseable = yes

[music]
path = /media/usbdrive/Music/MP3
valid users = @samba
force user = shareuser
writable = yes
read only = no
browseable = yes

From Windows 10 (192.168.0.229), I can access the shares by providing a password for shareuser. Then I can write files to any directory in the apps and music shares, but not usb - I get an "access is denied" error. The same directories that are inaccessible through usb can be written to when accessed through the apps and music shares.

Any ideas? I've tried playing around with different owners for the /media/usbdrive directory but it doesn't seem to help (but maybe I'm missing something).

  • What are the permissions and ownership on /media/usbdrive ? I wonder if it chown shareuser /media/usbdrive is all thats required? – davidgo May 10 '20 at 22:02
  • I changed it: drwxrwx---+ 11 shareuser samba 4096 Apr 9 12:07 usbdrive And it still doesn't work. – loosenut May 11 '20 at 05:15
