when I plug in my usb hdd, ubuntu 13.04 will mount it to /media/myname/label, but the umask is 700, I try to change it by "chmod 755 xxxxx", but no effect.
So, how to change default umask?
BTW: my usb hdd is stored some movies, I want to use plex media server to scan them, but pms cannot find anything from hdd path, so I think it is a umask issue.
This answer from UbuntuForums is sort of right:
You'll need to create an fstab entry that uses auto mount, I haven't done this in a long time but you could try adding the following to /etc/fstab:
/dev/sdx /path/to/mnt ntfs-3g auto,users,uid=1000,gid=100,dmask=022,fmask=133 0 0
Then umount and try plugging it back in to see if that works. If you just want the same permissions for file/directory you could replace f/dmask with umask.
The sort of wrong part is that it uses disk indices instead of UUIDs or disklabels. The point does, however, remain the same.
You can actually do the same entry with disk UUID.
Simply change the above thing into
UUID="" /path/to/mnt ntfs-3g auto,users,uid=1000,gid=100,dmask=022,fmask=133 0 0
sudo blkid will show you the UUID of the desired disk. PS- pay attention to the double quotes.
