Every (uncommented) line in /etc/fstab relates to a call of the 'mount'
command. The fourth column of the file contains the options.
The options to set the permissions depend on on the filesystem that is
mounted. Obviously, the file system you mount is of the type NTFS. According
to 'man mount', you must use "uid=value" to set the owser, "gid=value" to set
the group and "umask=value" (given in octal) to set the actual permissions.
The IDs of the owner and the group can be read in the advanced settings of
"System/Administration/Users and groups" or directly in the /etc/passwd and
/etc/group files. Are you familiar with the permissions in octal? Like 775
for "owner and group can do anything, whereas other can only read and execute
(not write)". If you want to know everything about permissions:
$ info coreutils 'File permissions'
The subsection focusing on the octal numbers for permissions is directly
accessible in this way:
$ info coreutils 'Numeric modes'
