I must remove the VCD from my My Passport Essential

It is imperative that we can remove the VCD from the above-mentioned drive (there are more than one).  It is using space that we need.  We were going to buy several of these drives to manage different sections of source code.  20 GB is just too much space to loose.  If we cannot remove this item, they will all be returned and exchanged for another brand.  Our management cannot believe that a company would be so bold as to sell a product with a piece of unnecessary software that cannot be removed.  This can only lead to a loss of sales.
