Do not have premission to write to internal media?

I have a 190gig data partition on my hard drive and it mounted just fine (gave it my password and it appeared in nautilus) how ever I have to be root to send files to it… Why is this and how can I change it so my default user can also write files to it as normal?


Who is the owner of the mount point? What are the access bits there?

The owner of the mount is who ever the default owner is when I select the drive in “computer”. What are “access bits”?

If you do not know where your partitions are mounted do:


it shows what partitions are mounted where and with what options.

Access bits are the bits that belonging to a directory/file and that say who may do what with them. The who part of this is user,group, others (or world), and the what part is read, write, execute/search. You see them when you do ls -l command of a file. E.g.

henk@boven:~> ls -ld /home/wij
drwxrwxr-x 10 henk wij 4096 jun 21 18:07 /home/wij

(the d is added because /home/wij is a directory, wthout the d it would show all the files inside the directory).
I showed this from my system because /home/wij happens to be a mount point. It shows that it is owned by the user *henk *and that the group *wij *is also connected to it. The drwxrwxrwx part shows:

  1. the d that it is a directory
  2. the first rwx that the owner (*henk *in this case) may read. write and search in the directory;
  3. the second rwx that users that are member of group *wij *may also read/write/search;
  4. the third r-x that other users may read and search, but not write.
    This is a very important concept in Unix/Linux.

When e.g.the mountpoint is something like:

drwxrwx--- 2 root root .... /your/mount/point

only root can do anything inside the directory, irrespective if the contents is there because of it being a mount point or not.
