How to format a booteable usb made by Startup Disk Creator

Question

I've made a usb booteable to install ubuntu with Startup Disk Creator, I want restore it to normal state and delete all files inside. When I try to format my usb i get the following error:

Solution 1

Install mkusb

sudo add-apt-repository universe  

sudo add-apt-repository ppa:mkusb/ppa  
sudo apt-get update
sudo apt-get install mkusb

Run mkusb and select restore to a standard storage device

Solution 2

I found a solution.

1. Open Disks from your dash

2. Select your pen drive

   I took this picture after deleting the partitions

   

   there will be 3 partitions.

3. Format the 1st partition by clicking the settings icon

4. Delete the other 2 partitions by clicking the - (minus mark/dash)
5. After that, format the whole pen drive again.

This will fix your problem.

Solution 3

Well I recommend to install GUI application gparted from the software center. Use this software to delete all the partitions you made in your USB and make it as a whole sole partition.

Note: GPARTED is a powerful application which requires root privileges to operate, so while formating if you choose your hard disk partition instead of USB for formating, then all your hard disk will be wiped off. So use it carefully if you are new to it.

Thats all.

No, nothing to do with it. exfat* just provides support for the Microsoft proprietary exFAT file system, typical of 64GB+ flash drives. It has nothing to do with the reported problem .

Right click, unlock it and delete all partitions before making new ones. For faster and better results install and use MKUSB (wipe menu).

Your answer could be improved by including more detail about the steps needed to remove or overwrite a partition table on a USB memory stick that has been through the Make Bootable Disk process. The warning is a good idea though.
