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.

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.

UPDATE 09/2020: Above link is official ext2fs informational microsite (non https protected), lastest sources are securely hosted on https://sourceforge.net/projects/e2fsprogs/. BTW author announced: "All users of e2fsprogs are urged to upgrade to the 1.45.6 version as soon as possible".

    While this may be an excellent answer otherwise, please note that the SourceForge link to the latest version uses the insecure HTTP protocol and as far as I am concerned it would be highly advisable to replace it with a more secure option (replacing the protocol part of the url doesn't work unfortunately). Partly flagging this up as I'm just humbly looking for the solution while you might have a slightly better looking link at hand :)

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.
