Have you disabled HDD requirements in the Options page? About sharing permissions, of course you can do it, once you go to the Sharing and Security page (with Simple Sharing disabled) in the folder (or drive) context menu it will be easy. I installed XP on one of my SATA drives that I will be using for storage I followed the guide over here: http://mason.gmu.edu/~sfiorito/eXPinstall.htm I followed the entire guide and I got to the point to copying everything from my hdd to CF. I tried copying everything from my hdd to the CF but the CF would not load up windows. It says something along the lines of "Disk error, press any button to restart". So now I'm going to try and re-do the entire process of installing XP and setting up the EWF, but directly on my CF card.. As for sharing permissions, I did get to the Security page but the only issue I have is that I can't set any permissions for users on the network.
