I just spoke with Sandisk Technical Support and they stated that they DO NOT RECOMMEND that ANY of their flash drive products be used as bootable drives. Which I wish I'd known before I shelled out money for this 16 GB Cruz. I wonder if there are any flash drive brands which ARE recommended?
Several Sandisks I have owned has software on it that loads when you stick the drive into your PC. Its been a while and I forgot what they call it. You will need to get rid of it, they have a utility to do it, and reformat the flashdrive as just a normal flashdrive and it will work fine.
