Sorry, but I agree with Sydney Polk.  Image backups are *NOT* the way
to go.  It is my understanding (after talking to Chinook's Technical
Support) that you can not restore an image backup to your hard drive
if the size of the partitions changes even slightly.  Moreover, it is
very likely that the size *WILL* change if you have to have your
drive itself replaced (as I had to do recently).  Fortunately, I had
a file-by-file backup taken by ProSel-16's Backup program.
