Thanks for the information. I borrowed a friends CF card and it works
fine with suspend and resume. I will put the microdrive back in my
camera, and get a 256MB or 512MB CF card.

I was going to use the microdrive for intimate until I ran across this
problem. I would have to keep the ipaq on all the time with the
microdrive or shutdown the system each time, if I use the microdrive.
