I just sent the following to Acronis support. "After installing 9.0 (home) I could not restore an image made with 8.0 that was on a 300gb external Maxtor drive. It stalled out about 3/4 through analyzing the 'D' (Maxtor) drive. I made several attempts with the same results every time. Once I left it 'analyzing' for a couple of hours with no movement in the progress bar. I reinstalled 8.0 and made the restore with no problems - except that it takes about 7 hours to do a restore from the image on an external drive."
