  1. I had the same problem with my USB stick drive recently. It wouldn't re-format completely in Windows, however I tried the same on Linux since I have that installed on my laptop on it worked fine. You could try using DOS to format your drive first just be careful which drive you format ;) Alternatively a Linux Live CD or a Virtual Machine may help if you don't have any joy in DOS.
  2. The newer USB flash drives have U3 installed. Read more about it here:

    To uninstall U3, see here:

    I just don't like manufacturers making assumptions regarding my needs. If I want U3, I will request (or pay) for U3.
