Looking to used disk imaging software to backup a marginal hard drive in preparation for replacement. I know cloning requires that I hold on to the old drive long enough to perform the clone. Disk image backup seems easier as I can do that ahead of time. Do the imaging programs install a boot loader so I don't have to an OS install before recovering the image. What about putting the image on a USB stick or on Onedrive. I experimented with Ease US Todo trying use a recordable CD and it hung up. I had to restart the computer to eject the CD. Suggestions or strategies appreciated.
