Query: Can't replace U3 launchpad except with SanDisk non secure program

Nice drive but went to the U3 site to update Launchpad program for Vista as directed. U3 site downloaded a sandisk program -- no indiaction that update applies to SanDisk drives only. By the time I figured that out, it was too late to use the vista update on the Verbatim site. The Verbatim site no longer recognized the drive as a "Verbatim" device. Neither Verbatim nor SanDisk support could/would help; both referred me to the other's support site. So, I am left with a U3 (SanDisk Launchpad) Verbatim drive that apparently does not and can not have a hardware "security" enable function -- which is what I bought the U3 drive for in the first place. So, I bought a new SanDisk U3 USB drive. Operator error? You bet, but one I couldn't seem to recover from without spending more money. You can research U3 and other flash drive security issues on [...].
