I am selling my IPAQ and want to clear all the data. I have tried hard resetting (holding down the two outer keys - calender and itask and pressing the reset button for five seconds) to no avail. I get the default Compaq screen plus a chime after five seconds but the data does not clear. I suspect that I must have previously selected an option to store data in ROM but cannot figure out how to clear it. Any suggestions would be greatly appreciated.
