I just brought an 8GB Sandisk Cruzer USB stick. Unfortunately whenever you plug it in, it comes up as both an emulated CD-ROM drive and the removable disk. the emulated disk comes up as “U3 System” and it tries to run backup/sync software called U3 Launchpad.
Some people enjoy these extra “benefits”, but I’m not a big fan of the bundled software and just want 8GB of storage space I can call home.
If you want to remove the built in software and just use it as a memory stick, you’ll want to use the U3 LaunchPad Remover from Sandisks’ Website. The link to it is: http://www.sandisk.com/driverdownload/download.asp?driverId=2
