I have a U3 smart flash drive that works perfect on my work computer, which is a Dell Deminsion (5 years old at that). But when I took the flash drive home to use in my "better" computer at home, the computer crashed. I had to manually reboot by pushing the off button. I did this 3 times, and it crashed my computer every time. Why doesn't the U3 smart drive work in my computer at home, but it does at work?
