I have issue mounting an usb drive.

After inserting the usb drive, I format disc via Disks app and then create partition ext4.

After confirming the Disks app close.

Then I am trying to mount but without success.

The command that I run is below:

sudo mount -t ext4 /dev/sda1 /media/usbdrive

Error appear:

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.

Disks details: https://ibb.co/cPJLk8

What I am doing wrong?

I want to use this as backup using deja dup.

The error usually appears when the drive is corrupted.
The kernel is unable to read the filesystem superblock, which contains important information regarding the structure of the filesystem.
I suggest you to try formatting the drive once more, using GParted.
Also try creating a smaller partition towards the end of the drive.
It may be that the blocks of the drive at the beginning is damaged.

Reformatting the drive did not fix the issue.
Using GParted, a new msdos partition table (also called MBR) was created.
Created a new partition and formatted it as Ext4 (quick format).
The drive was able to be mounted successfully.

  • Thanks for tip.. But when I open gparted, I don't even see on the list the usb... This was clean usb, I have installed IOS of ubuntu for install. Then I try format and partition, and failed on mount.
