Yesterday I began using a Lexar SecureII 2GB jump drive. All was working well, until I went to update the security software on it. After I formatted the drive, it began showing up as a hard drive on Windows XP. It's not my computer, because I tested it on 2 other computers, and each time it shows up as a hard drive instead of a removable storage device, and because of that, it is not detected by the Lexar software and I can't update it. Other people in my office have the same model jump drive, and theirs works just fine. How can I fix this thing so it shows up as a removable storage device like it's supposed to.
