Recently a friend brought me her laptop with a dead HD. She had luckily saved her data, but there was no saving the factory recovery partition which was damaged with the drive. She hated losing that since it had saved her bacon a couple times.
I had planned to just install something like TODO backup or Paragon, when I found this:
http://www.backup-utility.com/okr-free.html It's basically the same as a backup image program in that it creates a recovery partition (that can be hidden), only it is accessed on bootup by pressing a key -- just like any pre-installed factory recovery. Well, long story short, the restore worked like a charm twice! (Once for me, then for my friend who tried it to make sure it worked for her).
Personally, I prefer something like TODO, since I do a regular backups, while this utility seems more intended for factory backup/restore. But let's face it, many here don't do backup images at all, so this option would be ideal for them: a one-time, set and forget solution. Better to restore to factory setup, than have to spend a week reinstalling and activating software.
