I downloaded the free Shadowsurfer 2.5 from here. http://www.storagecraft.com/download.html Installed,used and liked it very well. I also use Casper XP 3.0 http://www.fssdev.com/products/casperxp/ to make full hard drive backups every other day and like it well also. My problem is Shadowsurfer will not let itself be backed up to a different hard drive by Casper even when Shadowsurfer is taken out of startup and is not active,just used on demand. Any others ran into this problem and if so is there a work around for it as I would like to keep using both programs? Thank's for any input.
