Format a USB Device after using Ubuntu Startup Disk Creator
Using the Ubuntu Make Startup Disk to create a bootable Ubuntu USB stick is one of the best ways to try or install Ubuntu.
However, formatting the USB device afterwards may prove troublesome for some users. This HowTo covers a simple solution if you ever encounter an error formatting the volume.
This partition cannot be modified because it contains a partition table; please reinitialize layout of the whole device. (udisks-error-quark, 11)
From your Desktop, open the application search (Super Key), type Disks and launch the application.
Select the USB device you want to format.
Leave the selected defaults, click format and confirm.
After formatting, the drive volume will be unallocated space. Next you'll need to create a partition by using the + button. Default values are fine here, optionally name the device by filling in the field and then click on create.
The device is now ready to used.
