"Failed to mount Windows share" error in Samba
What you want to do is add a "force user" line to that share definition so that the remote user appears to be you
[share-name]
comment =
path = /media/some-name
read only = No
force user = your-user-name
guest ok = yes
Try this.
I ended up using ntfs-config. The automount feature on it solved my problem.
