I am trying to access a full disk encrypted hard drive (sda) on my computer that holds a Linux Mint 18 install but I am unable to get it to mount. My current installation is on the same computer but on a different drive. (sdb)

I cannot boot from this drive. If I try the message is that it has no file system to boot from.

lsblk shows:

e2fsck:

sudo e2fsck /dev/sda1
e2fsck 1.42.13 (17-May-2015)
/dev/sda1: clean, 305/124928 files, 77714/498688 blocks

sudo e2fsck /dev/sda2
e2fsck 1.42.13 (17-May-2015)
e2fsck: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda2
Could this be a zero-length partition?

sudo e2fsck /dev/sda5
e2fsck 1.42.13 (17-May-2015)
/dev/sda5 is in use.
e2fsck: Cannot continue, aborting.

I can mount sda1 but when I try to mount sda2 the terminal shows:

sudo mount /dev/sda2 /mnt
mount: wrong fs type, bad option, bad superblock on /dev/sda2,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

and sda5:

sudo mount /dev/sda5 /mnt
mount: unknown filesystem type 'crypto_LUKS'

So I don't really know what I am doing which is probably why I have this problem in the first place but I was hoping somebody could help me to be able to mount the hard drive, if only read only, so I can pull some important files from it. I know my crypt password. Is there a way I can recover this data. Perhaps I can rebuild the file system?

Edit: I tried to mount sda5:

sudo cryptsetup luksOpen /dev/sda5 samsung
[sudo] password for user: 
Enter passphrase for /dev/sda5:

then:

/media/samsung $ sudo mount -t ext4 /dev/mapper/samsung /media/samsung/
mount: wrong fs type, bad option, bad superblock on /dev/mapper/samsung,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

Your drive is a LUKS container which most likely contains a LVM volume group. Before proceeding, make sure that you have cryptsetup and lvm2 installed.

  1. Open the container:

    sudo cryptsetup luksOpen /dev/sda5 samsung

  2. Activate the LVM logical volumes:

    sudo vgchange -aay

  3. Check what you now have in lsblk:

    sudo lsblk
