USB drive not recognized after Erase Disk

I was trying to create a bootable USB to install Lubuntu using Startup Disk Creator and I accidentally tapped on the "Erase Disk" option.

Now Ubuntu 12.04 doesn't seem to read my USB drive anymore. I tried using GParted but it doesn't seem to recognize it either.


You may have lost the partition

  1. Open Disk Utility from Dash and select click on the partition that you would like to change, or on the unallocated disk space that you will be using for a partition. If the disk space is currently unallocated, it will be labeled "Unrecognized" in the Disk Utility

  2. Click the drop-down menu next to "Create Partition Table," and choose "Master Boot Record." Click the "Create" button at the bottom of the window.

  3. Click "Create." You will see a warning reminding you that this process will remove any existing data on the partition. If you are sure that the data on the partition (if any) has been backed up, click "Create" again.

  4. Enter your root password. The label for the hard drive partition will change to "Unallocated Space." Click it.

  5. Click the drop-down menu next to "Create File System" and click "NTFS."

  6. Type a label for the partition, if you would like to use one.

  7. Click "Create." You will see a warning reminding you that this process will remove any existing data on the partition. If you are sure that the data on the partition (if any) has been backed up, click "Create" again.

  8. Enter your root password. The NTFS partition is now created.

  • This is no longer a problem with the Startup Disk Creator in Ubuntu 16.04 LTS and newer versions.

  • But Ubuntu 14.04 LTS is still supported. I suggest that you use another tool in that version, for example the built-in Disks alias gnome-disks or some other tool, for example mkusb.

  • You can use Disks or mkusb to wipe or restore a damaged USB drive or memory card,

    • wipe='overwrite with zeros' (will remove the partition table) or
    • restore='restore to a standard storage device' with an MSDOS partition table and a FAT32 file system.
