I had the a San Disk reader that I bought shortly after I got my KN7000. It worked fine on my Win 98 machine. However, it started acting weird a while ago. I'm not sure if it had to do with WinXp or if it just went bad. It started taking forever for backup and retores. One of my 64SD cards always locked up my machine. I thought the card was bad, but then I found out it worked fine in my KN7000. I bought a new car reader a little while back and suddenly all the slow tranfers went away and my 64meg Sd card worked again.
