How to stop mounting all hard drives at startup in Ubuntu?
 
I am running Ubuntu precise (12.04).
I installed and ran ntfs-config because I was an error while trying to copy files from my hard drive to a usb device. After checking the
'enable write support for external file'
box that issue was fixed; however, all my hard drives got mounted for some reason. I unmounted them with:
$ sudo umount /dev/...
but when I restart the computer they are all monted again. Is there a way to make sure that they don't mount upon startup?

If they are in /etc/fstab, you could set the mount to "noauto."

Here's a line from my fstab. Where it says "auto," substitute "noauto." Then you will have to mount them manually, either from the command line or through the file manager:

Code:
UUID=7900ade7-de36-41e5-88b5-2d7aaa8adcd4      /media/sdb5    ext3    rw,user,auto    0      1
If the entry in your fstab is significantly different, post it here and we'll help you.

You can learn more about fstab here: http://pclosmag.com/html/Issues/200709/page07.html

Thanks for your quick reply; unfortunatelly, I don't see 'auto' option anywhere, so would really appreciate your help. Here's the file's contents. Out of the once listed I only need sde5 mounted.

Code:
# /etc/fstab: static file system information.
#
# <file system> <mount point>  <type>  <options>      <dump>  <pass>

proc        /proc        proc        nodev,noexec,nosuid        0        0
#Entry for /dev/sde5 :

defaults is actually many options i.e.
rw, suid, dev, exec, auto, nouser, async, and relatime

The simplest would be to use defaults,noauto. The noauto takes precedence over the defaults.

I was thinking I should have said more, and I see that michaelk has added a most useful post.

If you are not sure which partition is represented by a particular entry in your fstab, you can use the blkid command. For example:

Code:
$ /sbin/blkid
/dev/sda1: UUID="ad52eed9-c80c-41fe-81a6-e8a9a71e6f19" TYPE="ext3"
/dev/sda5: TYPE="swap" UUID="35f7217b-f73b-4cd1-b513-571bd0482a18"
/dev/sdb1: UUID="1655a198-15a7-471f-9e99-e3fc9fd92ca0" TYPE="ext3"
/dev/sdb5: UUID="7900ade7-de36-41e5-88b5-2d7aaa8adcd4" TYPE="ext3"

Isn't there something about automounting usb media?

michaelk 06-20-2014 09:50 PM
Yes... You can disable the gnome automount setting via gui dconf-editor or the CLI tool gsettings. I assume that you are using gnome.

settings set org.gnome.desktop.media-handling automount false

I tried installing dconf-editor and unchecking the box for 'org.gnome.desktop.media-handling automount' but to no avail. I'm afraid to mess with /etc/fstab file without really knowing what I am doing. From the posts above I gather that I can substitute
Code:
defaults,noauto
where ever I have
Code:
defaults,nls=utf8,umask=0222
that is do I do change the previous line to example 1:
Code:
defaults,noauto,nls=utf8,umask=0222
or to example 2:
Code:
noauto,nls=utf8,umask=0222
Also I think that the problem that I am experiencing now is a result of installing ntfs-config which overwrote my original /etc/fstab is there a way to get those settings back?

UPDATE: Okay I looked in the /etc and found a file called fstab-ntfs-cofig-save so I just replaced the fstab file with it and everything started working as desired :)
