I am unable to access the rest of my D: drive while using my dual booted Ubuntu. It doesn't show in other locations and it just doesn't mount. keeps saying " not found in /etc/fstab". I realize that my C: drive is encrypted but I should be able to access my non encrypted D: drive as my Ubuntu partition is also in D:

    C: and D: are probably single partitions in Windows, try the lsblk command in linux to "see what it can see". And what command were you using to try mounting it, that gives the error "not found in /etc/fstab"? – Xen2050 Mar 2 '19 at 13:49

You must provide a mount point in order to mount a disc. The mount point can be any directory in your file system, but Ubuntu by default uses /media/ for its mount points.

In its simplest form the mount command is:

mount Source Directory

Here Source is the device address of the disc to be mounted (eg /dev/sda6) and Directory is the mount point.

If you add an entry for the disc in /etc/fstab this has two effects:-

  1. The disc is mounted automatically during the boot process.
  2. The mount and umount commands do not need both the Source and Directory commands: either can be used, and the other is inferred from the fstab entry.

You can also use the GUI Disks program to see your disc layout and mount individual partitions. In this case a mount point is created automatically in /media/UserName/, where UserName is the currently logged-in user. You can also dismount discs that you have mounted with Disks, but not fstab entries.

Disks layout

This is a powerful utility and it's easy to use, but maybe too easy to use, as next to the Mount button is the Delete button, which will lose your partition. Use with care!

You should look at the manual pages, man mount and man fstab. There is also a man gnome-disks page, but this has little information: use the in-program help F1 instead.

  • thanks a lot, i figure out that the issue was actually with bitlocker encryption on the drive that i was able to see with GUI disks – Arijit Gupta Jul 17 '19 at 8:51
