Another issue: If there's any need to revert the computer to the prior 
version of Windows, there is limited time to do this. In the upgrade, 
Windows makes a backup of the prior version that eventually gets wiped out.

With a drive image backup, the needed files for reversion can be 
restored to allow doing that beyond the time limit. So there are reasons 
for drive images beyond device failure - "Whatever it takes to get the 
computer back the way it was."

Further info on Parted Magic: it's a Linux live distro, apparently based 
on Gentoo. It includes lots of software for working with hard drives, 
including GParted and Gnu ddrescue.
