Recently, after a sudden power failure, my 1tb hard drive (/dev/sda1) failed and will not mount. It says, Error mounting /dev/sda1 at /media/zangar_/4b84d62b-520d-408e-addc-7a2bf52cc4e3: Command-line ``mount -t "ext4" -o "uhelper=udisks2,nodev,nosuid" "/dev/sda1" "/media/zangar_/4b84d62b-520d-408e-addc-7a2bf52cc4e3"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error

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

I tried e2fsck but it asks me to Get a newer version of e2fsck! Then, I looked at all the other posts about updating e2fsck (here and here.) These answers did not work for me. My problem!

Any help is greatly appreciated, as i have time sensitive documents in the unmountable drive.


Boot to a Ubuntu Live DVD/USB 16.10 (prefer DVD). It must be 16.10 or higher.

Open a terminal and type sudo fsck -f /dev/sda1.

Now you may be able to mount the drive as normal.

Using a live CD/DVD/USB seems like a workaround that may not be always applicable.

I believe that the correct answer how to have e2fsck updated is to compile latest version from the sources.

  1. Download the latest version (1.44.3) from http://e2fsprogs.sourceforge.net/ and unpack in a directory and cd into it.

  2. According to the INSTALL document:

    mkdir build; cd build
    sudo make install
  3. Check that you have new version now:

    $ e2fsck -V
    e2fsck 1.44.3 (10-July-2018)
    Using EXT2FS Library version 1.44.3, 10-July-2018

Note: you may need to install compiler and tools with apt get install gcc.
