I have bought a SanDisk Cruzer 1 GB thumb drive, which incorporates something called the ?U3 System?. I only wanted the thumb drive to be a data repository, and have found the U3 to be distracting and very annoying with all its pop-up windows and menus that appear when the drive is inserted into the computer. The thumb drive appears within Windows as a removable disk and also a CD-ROM drive. In an attempt to remove U3 I found a program called ?Launchpad Removal Program? on SanDisk?s website, but this does not seem to work. Subsequently, I also tried formatting the drive but this also did not remove U3. Looking through Disk Management I found that the removable drive and CD-ROM drive portions of the thumb drive are classified as partitions on the thumb drive, but cannot be removed (as the ?Delete Partition? button is disabled). Can you please explain how U3 can be removed from the thumb drive?
