Bug Description

I used your Image Writer software in a 4GB usb pendrive to write an image of a live version of ubuntu. Everithing went fine. Thankyou.
The problem is now, after the test. When I'd like to return the pendrive to its FAT-32 original format.
I tried to format the device with Vista and XP and both only allowed me to format as 640Mb capacity. I couldm't find any place to say that the capacity is 4GB.
Could you please help me?

Thank you for using Ubuntu software. After using your usb drive to boot/install Ubuntu, to revert back to a normal USB drive, you can do one of two things.

In Ubuntu Linux, you can install and run gparted, and use it to delete and reformat the partition(s) on your USB drive in any format supported by Linux (fat16/32, NTFS, Ext2/3/4, etc).

In Windows, you will need to download and install the "HP usb disk storage format tool". You can find numerous links by copying the term within the quotes and pasting it into search. This utility should also reformat the drive, but it may have some limitations, and is not supported here.

Hope this helps.

Had the same problem.

My solution was to write a 4GB image to the USB key and then format it in windows.
This way I got back full capacity of my USB stick.

I also had the same issue but you can get the full capacity back by formattting the USB from "Computer Management-Disk Management"
1-Right click "My computer" & open "Computer Management"
2-Go to "Storage" -Disk Management
3-Format the USB

RMPrepUSB will allow you to format a USB device as FAT32 even larger than 32GB. Works under XP and later OS's.
