Ubuntu: SD card content not showing up in Ubuntu


I have burned OS image (.img) into a new SD card (Sandisk 16GB) use LibreELEC USB-SD creator tool on Ubuntu laptop. I assume I don't need to format SD card before writing. Then I tried browse SD card for files, but Ubuntu not able to show the contents of sd card. It only show space available on SD card. I tried also to browse SD card on Windows PC, but it don't recognized it, when click on SD card drive icon, Windows show alert that SD card first need be formatted. There is also listed volume 537 MB, it can't be opened, when try click to mount it, error message is displayed:

Unable to access "537 MB Volume"    Error mounting /dev/mmcblk0p1 at /media/venitek/3463-3434: Command  line 'mount -t "vfat" -o "uhelper=udisks2,nodev,nosuid,uid=1000,shortname=mixed,utf8=1,showexec,flush"  "/dev/mmcblk0p1" "/media/venitek/3463-3434"' exitedd with non-zero exit status 32: mount: /dev/mmcblk0p1: can't read superblock  

Edit: here is output fdisk -l command:

$ sudo fdisk -l  Disk /dev/sda: 465.8 GiB, 500107862016 bytes, 976773168 sectors  Units: sectors of 1 * 512 = 512 bytes  Sector size (logical/physical): 512 bytes / 4096 bytes  I/O size (minimum/optimal): 4096 bytes / 4096 bytes  Disklabel type: dos  Disk identifier: 0xb45e11b8    Device     Boot     Start       End   Sectors   Size Id Type  /dev/sda1            2048    718847    716800   350M de Dell Utility  /dev/sda2          718848   7010303   6291456     3G  c W95 FAT32 (LBA)  /dev/sda3  *      7010304 960389119 953378816 454.6G 83 Linux  /dev/sda4       960391166 976771071  16379906   7.8G  5 Extended  /dev/sda5       960391168 976771071  16379904   7.8G 82 Linux swap / Solaris    Partition 4 does not start on physical sector boundary.

I tried also commmand dd if=/dev/sdb1 bs=1024k count=10 | less, it show just vertical list of tilde ~ chars, not sure if it's readable.


The ability to write .img or .iso files is built into Ubuntu, don't use some weird third party tools. Either just double-click on the .img file in Nautilus (the file browser), or right-click on it and then select to pass it to the image writer. Select your SD card as target and choose to "recover" the image.

If your Windows can read the resulting USB or not depends on the file system that is written to the card.


Please follow the below steps and it should fix this for you.

  1. Remove any SD card that are inserted into the SD card reader.

  2. Launch the terminal.

  3. Run the following command to reinstall udisks2.

    sudo apt-get install --reinstall udisks2  

    You will have to enter root password to complete reinstallation.

  4. After the installation is complete, close the terminal and reboot the PC.

  5. Try inserting a SD card into the SD card reader slot. It should work now.
