I've written:

/dev/sda2 /win ntfs-3g rw,dev,exec,auto,async,users,umask=777,uid=1000,gid=1000,locale=en_US.utf8,  errors=remount-ro 0 0

but I still can't access /win as a user (corresponding to uid/gid specified). As root I can access /win and can see that no permissions are set at all (I supposed umask=777 is meant to set all permissions).

Why dev,exec,async? – karthick87 Dec 19 '10 at 14:58
@karthick87 exec because I want to be able to execute, dev and async because they are included in default and I don't know what's their actual impact is. – Ivan Dec 19 '10 at 15:08
Try this /dev/sda2 /win7 ntfs-3g defaults,user,noauto,uid=1000,gid=1000,umask=022 0 0 – karthick87 Dec 19 '10 at 15:20

With umask you define the options that should not be set. So umask=777 is the same as octal permission 000.

For some examples on how to convert between octal permissions and umask, see this Wikipedia entry.
