I've been trying to set up my Raspberry Pi B+ as a HTPC that also shares a USB HDD over Samba and AFP. The latter is working just fine, and the Samba share seemed to be working too for a moment. However, whenever I try to connect to the Pi now (no modifications AFAIK) it shows me the folders with small stop icons. The following links unfortunately didn't offer me any help.


sudo mkdir /mnt/Data
sudo chown osmc:osmc /mnt/Data
sudo chmod -R 777 /mnt/Data
sudo apt-get install exfat-fuse exfat-utils


/dev/sdb2 on /mnt/Backups type hfsplus (rw,nosuid,nodev,noexec,relatime,umask=22,uid=1000,gid=0,nls=utf8)

/dev/sdb3 on /mnt/Data type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other,blksize=4096)

cat /proc/filesystems | grep fuse

nodev   fuse
nodev   fusectl

I've tried the following:

  • changing "exfat" in /etc/fstab to "fuse-exfat", "exfat-fuse", "fuseblk". All without luck.
  • manually mounting using:

    • sudo mount /dev/sdb3 /mnt/Data
    • sudo mount -t exfat /dev/sdb3 /mnt/Data
    • sudo mount -t exfat-fuse /dev/sdb3 /mnt/Data
    • sudo mount.exfat /dev/sdb3 /mnt/Data
    • sudo mount.exfat-fuse /dev/sdb3 /mnt/Data


   workgroup = HOME
   server string = %h server
   dns proxy = no

   log file = /var/log/samba/log.%m
   max log size = 1000
   syslog = 0
   panic action = /usr/share/samba/panic-action %d

   security = user
   encrypt passwords = true
   passdb backend = tdbsam
   obey pam restrictions = yes
   unix password sync = yes

   passwd program = /usr/bin/passwd %u
   passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
   pam password change = yes
   map to guest = bad user

   usershare allow guests = no

   comment = OSMC
#  browseable = no
   path = /home/osmc/
   valid users = @users, root, osmc ###this seemed necessary according to a guide
   force group = users
   create mask = 0777
   directory mask = 0777
   read only = no

The funny thing is, on every single one of these commands. The /mnt/Data privileges change to (drwxr-xr-x, root:root) and go back to normal when I unmount the volume. I'm guessing OS X won't let me browse into any directory as it is owned by root and I'm connecting as osmc. What seems to be going wrong here?

I noticed that by default, OSMC also shares external HDD's over Samba. On connecting to the Raspberry via Samba, I get the following options:

  • osmc
  • homes (not relevant in this case)
  • Data (ExFat partition on HDD)

When connecting to osmc, from my understanding, it serves me /home/osmc which has symlinked folders that I put there, e.g.: /home/osmc/Movies -> /mnt/Data/Movies

This results in the behaviour I mentioned before, giving me red warning circles on the folders. However when connecting directly to 'Data', everything works fine. I figured this would suit me and couldn't be bothered waiting for an answer here as I'm really impatient.
