Have you tried with the old fart fdisk

sudo fdisk /dev/sdh

Then delete anything that exists there, create a new partition, set type to "c", write partition table to disk and then reformat?
Myself, I have hade some problems with large sticks, in particular USB3. Using them in a USB2 port may work better, for instance.
You can also check reading/writing to the disk before running flash-knoppix, and keave the formatting out.

@Capricorny
I followed your advice but without success..
I'm not an expert in Software and I still think there is a difference in the 'flash knoppix' of the different versions, V7.03DVD/CD and V7.02!

I close the case for me and run 7.03 from 8GB or 16GB USB flash drives!
