When creating a bootable USB stick with Blancco USB Creator 2.3.0 and the "Format" option is selected, only a few megabytes of storage space is left on the USB device. This becomes a problem only if the USB stick is used to store data later on. It is quite common to use the bootable USB sticks also for saving Blancco erasure reports. A couple of megabytes provides plenty of report storage space, but for any other use a few megabytes of free space is not sufficient (for example storing Blancco ISO images).
If the USB stick needs to be used for other purposes than booting Blancco ISO images and the full storage space needs to be restored to the full capacity, this will require the use of DiskPart (Windows) or GParted (Linux).
During the bootable USB creation process, the USB media is re-partitioned to one partition. This partition is the same size as the files required by the Blancco software. Using the "Format" option has been known to minimize booting related issues with some systems.
The first solution is "pre-emptive" and should be used if the USB stick is needed for storing larger amounts data than a few megabytes. The second solution is for "fixing" the USB device.
