Can read but cannot write to Samba share

I'm trying to set up a Samba share that is only accessible by a particular user. I'd like that user to have read/write access to all files in the share.

The smb.conf file below will let me access the share through the one user 'patrick' but I can't get write access to work - I cannot modify or delete files on the mounted share via windows. The user does have the proper permissions set for the directory per below.

How can I enable read/write access? I do not want to change the directory/file permissions to 0777 like many of the other forum posts would suggest.

Directory permissions:

drwxr-xr-x   6 patrick patrick  4096 Jul  3  2015 ./
drwxr-xr-x   3 root    root     4096 Jul  1  2015 ../
drwxrwxr-x+ 15 patrick patrick 65536 Jan 22 00:01 music/

The smb.conf file:

[global]
   workgroup = WORKGROUP
        server string = %h server (Samba, Ubuntu)

#   wins support = no
   dns proxy = no
   log file = /var/log/samba/log.%m
   max log size = 1000
   syslog = 0
   panic action = /usr/share/samba/panic-action %d
   server role = standalone server
   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 = never

   usershare allow guests = no

[Music]
   comment = Music on Ceres
   path = /mnt/largemarge/music
   valid users = patrick
   browseable = yes
   guest ok = no
   read only = no
   create mask = 0775
   directory mask = 0755
   force user = patrick

Solution 1:

After hours of searching, I discovered that the share name and the share directory cannot be the same (and it's not case-sensitive, either). See this post on serverfault.

So, if I change my share name in smb.conf from:

[Music]

to

[Tunes]

I can both read and write to the share. No other changes to my smb.conf were necessary, and no need to chmod 0777.
